Cuba is skipping its November 1, 2026 clock change and staying on DST until 2027(timeanddate.com)

This article mentions that Cuba tried permanent summer time in 2004-06. This makes me wonder, has anyone ever tried permanent summer time and not given up? I know Russia attempted in 2011-2013[1] (before switching to permanent standard time), and the US did it in 1974[2] before going back. I know British Columbia did it this year, but I wonder how long that will last. BC is pretty North, and I wonder how local Canadians will feel about the very dark mornings in winter.

Edit: Updated comment to say "permanent summer time", since "permanent DST" is rather incompatible a statement.

I'm very much the kind of person that prefers the sun extending in the afternoon than the downside waking up in the night. The current "normal" makes the days feel more easily as "lost".

[–] irdc 20 hours ago

There is likely a minority of people who are not significantly affected by a lack of morning light and therefore prefer having light in the afternoon. However, the way we set our clocks must work for society as a whole, and there is an abundance of medical research demonstrating the importance of morning light.

[–] mhitza 19 hours ago

Glad to hear that the tyranny of majority works at a societal norms level. Hopefully at some point that will be the case with democracies as well, instead of serving the privilege of few very wealthy individuals :)

I'd like to imagine a parallel universe where society has decided that given shorter days, as law, working hours must be reduced during the winter period to allow people to wakeup and leave work while the sun is still up. And for those unfortunate ones that work during night shifts the bonuses are significant for their added Vitamin D deficiency and life disruption.

[–] bryanlarsen 19 hours ago

The stated preference of the majority in surveys is permanent daylight time, more sunlight in the evening and less in the morning.

The revealed preference is the opposite. Most people, when given the option for flex time, will start and end work later, increasing their morning sunlight and decreasing their evening sunlight.

Voting works on stated preference, so we'll likely end up with permanent daylight time.

[–] Izkata 17 hours ago

I see that example as the opposite, people just like to sleep in in general, and later sunrise/sunset gives them more light in the times that matter. They don't cancel out, doing both gives the best result.

You have to know ahead of time whether people value their sleep over sunlight, or sunlight over sleep, to know which version makes the most sense.

[–] zamadatix 17 hours ago

I've started to despise revealed preference for precisely this scenario. When it's applied accurately it rarely says anything normal reasoning couldn't already make abundantly apparent but it's soooo easy to inaccurately apply and then the conversation goes off the rails to focus on what the revealed preference does/doesn't say.

[–] vintermann 19 hours ago

Why is it so hard to set our schedules instead of our clocks? Can't we just agree that school starts an hour later in winter, for instance?

[–] sokoloff 19 hours ago

Then parents who do morning routine or drop off have to come in an hour later, and their partner also wants to wake an hour later so they can stay up with the family an hour later, which means they don’t want to open the coffee shop until an hour later, so now the random commuter wants to start later so their coffee shop is open, and pretty soon it’s just as easy to say “ah screw it, we’re just going to change the clocks twice a year…”

[–] christophilus 19 hours ago

Or, we come up with a system that actually follows the rhythms of nature, rather than forcing a standard schedule year round. Like, I get up later and go to bed earlier in the winter like pretty much every other mammal on the planet, and the 9-5 can shove it. This has nothing to do with clocks changing. Just our patterns changing.

I’d like a single, consistent way to mark time, but that shouldn’t dictate my seasonal schedule and rhythms.

The clock-driven day is one of humanity's greatest inventions. You can't build a spacefaring society on "following the rhythms of nature."

[–] nozzlegear 15 hours ago

Parents already have to make adjustments to their schedules for when their children are out of school in the summer, right? It's not like society isn't used to parental schedules shifting based on the time of year.

[–] uludag 18 hours ago

One of my favorite life hacks (which really isn't a hack) is to not change my clock, go to sleep and wake up at the exact same time (solar wise, not wall clock), and just view the shift as a shift in schedules as opposed to time.

[–] diskzero 15 hours ago

This is somewhat what it is like for me in Arizona. There is no clock change here, so I just watch my out of state meetings shift around twice a year.

[–] 1718627440 14 hours ago

Because the opposite is true. Schedules used to be earlier in the past. People simply want them later, despite stating otherwise.

[–] seanmcdirmid 15 hours ago

It’s a majority of people who aren’t farmers and don't wake up at 6AM to feed the chickens in the dark (chickens would wake up with the sun anyways). They’ve done polls on this and it comes up to cities want permanent summer time, and farming communities don’t.

[–] 1718627440 14 hours ago

There is no absolute value of when to do things. People used to get up at 6am or even earlier. Over the past century everything became several hours later, so the opposite of the stated preference of doing everything an hour earlier.

This just seem to be another case of people tell you different things, than they do.

[–] tzs 8 hours ago

> They’ve done polls on this and it comes up to cities want permanent summer time, and farming communities don’t.

...and then when they actually try most of the people who said they wanted it find out that they don't actually want it.

[–] rolosa 20 hours ago

The best part of winter for me is waking up in the dark, going to work in the dark, and driving home in the dark. I don't get affected by SAD and it's much more pleasant to me when it's not sunny.

[–] thousand_nights 20 hours ago

i mean us night owls have been used to society fucking us over with their schedules for our whole lives, it's nothing new

[–] OroPla 19 hours ago

Just go to sleep with the sun. Whatever we do to your clocks won't affect the sun.

[–] nonamesleft 18 hours ago

4h 40m in midwinter, 20h 20m in midsummer :D (plus nearly permanent twilight) - i suppose that might work if i was a bear that hibernates (and i believe the bears are right about this).

[–] vintermann 19 hours ago

Around here, that would be pretty much hibernation.

[–] watwut 19 hours ago

That is too soon. I would go to sleep before kids come back from after school activities. Most of the colleagues would still be at work when I go to sleep too.

[–] OroPla 19 hours ago

The sun won't be affected by what you set your clock to. If you want to optimize your schedule for sun exposure, you can do so. You can even travel twice a year near the poles to get sun all day everyday. Or no sun ever, if that's your jam.

[–] Izkata 17 hours ago

...so go to sleep while I'm still at the office at 4:30pm?

[–] bluGill 21 hours ago

Alberta is doing the same November 1st as well - they are even getting their own timezone...

(lots of rush work, Microsoft is still "validating" this new TZ in M365/SPO/OneDrive, users who tried to use that new TZ yesterday, changing their SPO sites end-up broken and unable to load without hitting system pages via URL... users who had changed their desktop OS TZ couldn't edit List items... it was a "fun" day...)

[–] lucideer 20 hours ago

(assume when you say "permanent DST" you mean "permanent Summer Time" since "DST" is just a description of the overall switching convention, not any particular season)

Interestingly, in Ireland, the time definitions are reversed from most places - summer is standard, "Winter Time" is the deviation. This has the effect of aligning the "official" time with mainland Europe (Irish Standard Time = Central European Time) in theory, but never in practice.

Given that, if Ireland were to adopt the EU's plans to drop DST, there's a reasonable chance they could keep summer time.

[–] jprjr_ 20 hours ago

In the US we switch between "(zone) standard time" to "(zone) daylight time" - Eastern Standard Time to Eastern Daylight Time.

So "permanent daylight saving time" makes sense to us since we use the term "daylight time" where Europeans tend to call it "summer time."

Still true that DST really just describes the overall time-changing process, just giving some insight into why the phrase makes sense to us.

[–] throwaway27448 19 hours ago

I think daylight time refers to the winter because it's emphasizing daylight? Always struck me as terribly named and never learned to differentiate until now

[–] Izkata 17 hours ago

In the US, I also only say summer time/winter time because I can never keep straight which is which.

[–] andy81 18 hours ago

You have it backwards, DST is for the Summer.

Winter is the standard clock. DST would be pointless in Winter - at latitudes where it matters you'd be shifting daylight from one active working hour to another.

[–] dubcanada 22 hours ago

Mornings are still dark doesn't really matter

[–] birdsongs 21 hours ago

Norway. Same.

At the peak of the shift (usually when DST comes into or out of effect) we're either losing or gaining an hour of daylight per week.

Throwing an hour shift one way or the other does nothing for us. And in peak winter the sun isn't up for me until 10 anyway, and it's down by 3, so what are we even saving?

[–] mrweasel 21 hours ago

It apparently mattered enough that Russia reverted it's decision to stay on DST.

[–] dubcanada 15 hours ago

Russia reverted to stay on PST, permanent standard time aka winter timezone. Which is what most people recommend for northern places. Southern places you'd probably want the reverse of that.

[–] konimex 20 hours ago

Ah, the perks of living on the equator. Sun rises at 6, and sets at 6 (give or take 15-30 minutes).

I was a bit surprised when I visited a country in the northern hemisphere in the winter since it's still dark at 7.

[–] gus_massa 19 hours ago

Here in Argentina we are in permanent summer time GMT-3 since a long time, but we should be in GMT-4. For some time during summer we had double summer time GMT-2.

But 20% of the surface of Argentina should be at GMT-5. It's easier fot transport and communication to ignore it, instead of splinting the country in two time zones in particular because it includes there are only a few big cities there. Anyway, they usually have double summer time but during that period they had triple summer time! There were a lot of complains from Mendoza and other cities there, and for some time we had a few actives time zones.

It was a nightmare to configure the time in the computer, because we didn't have a timezone and Greenland was not making random funny changes. We also canceled one of the switches a week before the date, so whoever is in charge of that in each OS still hate us.

I'm not sure if it's related, but we had very popular TV shows at "midnight".

[–] froh 18 hours ago

the closer you are to the equator, the less DST makes a difference. further north if anything you'd want permanent winter time. there (i.e. here, de_BY) DST gets you 1h more light in the afternoon evening when there is plenty of daylight available, i.e. March-Oct.

[–] jefftk 21 hours ago

Many places are permanently ahead by at least an hour, including Spain, western China (+2), and Argentina.

https://en.wikipedia.org/wiki/Time_zone#/media/File:Solar_ti...

[–] Svip 20 hours ago

In China it's due to the state wanting all of China to be at Beijing time, and for Beijing, it is standard time. As for Spain, Franco switching to German time, because he liked Hitler, and Spain never switched back. Besides, Spain observes DST like the rest of the EU. Argentina is however an example of a country that switched to permanent summer time and sticking with it (since 2009).

[–] jefftk 20 hours ago

Whether we call it "permanent summer time" or "aligning with the political region to the east" it's the same thing: late sunrise, late sunset.

(Spain is effectively using single-double DST, based on the delta from solar)

[–] ralphm 19 hours ago

Well, most of western Europe stayed on CET after World War II. Initially the Nazis forced this upon The Netherlands, Belgium, Luxembourg and occupied France in May 1940, including DST. Double summer time! As The Netherlands was on Amsterdam time before the war, it went from +00:20 to 02:00 in one go. Spain followed as a gesture of political solidarity. DST remained year round until 1942.

After the war DST was abolished again, and then reintroduced in 1977 because of the energy crisis.

There has been talk about having permanent (double) summer time again, but the problem is that in winter, sunrise would be around 10 am.

[–] wafflemaker 22 hours ago

If they still move time back in spring, they will gain 1h per person.

If they keep doing it indefinitely, they're looking at some serious profits and boost to GDP.

[–] throw-qqqqq 22 hours ago

Haha I know a skit from 1990, where the comedian makes this exact point.

He even takes it a step further:

“Why settle for turning back time just one hour? Think about how much we f*cked up the world in the past 30 years! Let’s turn time back 30 years and fix that mess!”

[–] Leonard_of_Q 20 hours ago

Not to mention they'll need far fewer candles cause it'll be light at night. Nobody burns candles during the day, sun's up at night so no need for them, profit.

[–] jamesbfb 20 hours ago

This made me giggle. Living in Australia，being from a state where we do have DST, we loved to make the joke that Queenslanders (who do not have daylight savings) would enjoy the lack of daylight due to their curtains (drapes for those across the ditch) lasting longer.

This is Cuba we're talking about. Profits only matter if they go to the ruling family and friends.

[–] berkes 22 hours ago

That's unnecessary political stereotyping.

But what does matter in Cuba, is Savings.

The country is in shambles, beyond bankruptcy, in cases literally starving. Because of it"international" sanctions. Severe shortages of petrol, water and energy.

So it wouldn't be surprising if, by moving the clock every year in just one direction, petrol, water and electricity is saved. And it wouldn't even be suprising if that actually happens.

[–] stavros 22 hours ago

It's not stereotyping when it can be applied to basically every country in the world, including the US.

[–] w3ll_w3ll_w3ll 22 hours ago

In EU it's currently stalled because some countries want to stay permanently on their DST time (south europe) and others (north europe) want to stay on their solar time.

It's better to make a common decison about this, so we are stalled.

[–] mcv 22 hours ago

It's weird to standardise on summer time instead of standard time. It moves you one timezone to the east. And in western Europe, a lot of countries are already on central European time. Permanent summertime would put them on eastern European time, same as Kyiv. In winter the sun wouldn't come up until 9:30.

[–] LluisGerard 22 hours ago

In Spain most people I talk to want permanent summertime because they like having sun late at the evening during summer, and they can't stand it when in winter the sun sets at 17:00. I think the issue is that a lot of offices work from 9:00 to 13:00 and 15:00 to 19:00. I remember when working on an office in Barcelona and having to drive 1 hour. I would leave home in darkness and drive back home in darkness.

[–] CiaranMcNulty 22 hours ago

It’s also because Spain being on CEST makes little sense, with its longitude

[–] cromka 21 hours ago

I personally think we'd be better off without summer time but with more timezones in EU.

[–] mdlxxv 21 hours ago

Spaniard here. I'm one of those few weirdos that desperately need daylight in the mornings to properly function, especially in autumn and winter, and couldn't care less if it gets dark earlier in the evening. I might even welcome it, especially in summer. We are rare, but we exist!

Spain is already in the wrong time zone for standard time, and when DST hits, it's two hours off the time we really should have. It's unnatural for daylight to last until 22:00 or nearby in june and july in Spain's latitude. A bit more and we'd end up with some kind of midnight sun, like we were in the Arctic Circle. It's ridiculous.

I mean, it's usually so hot, and getting hotter every year, that you can only go outside somewhat comfortably after nightfall anyway, so I'd actually prefer if it got dark at 20:00 or earlier in the summer, as it should be. On the other hand, it's horribly demoralizing for me when it's almost 8:30 in the morning in mid-october and it's still so dark. Going back to standard time, like we did a few days ago, gives me a brief respite, but unfortunately dark mornings will soon return in a month or so.

[–] mrweasel 21 hours ago

> Spain is already in the wrong time zone for standard time

That's probably even more of an issue for Spain, made even stranger by the fact that Portugal is in the "correct" timezone.

[–] atherton94027 20 hours ago

This is a consequence of WW2, Spain and France moved to CET to align themselves with nazi germany. Portugal and the UK didn't.

[–] pjmlp 19 hours ago

Yeah, it is even more weird when going from Portugal to Galicia, as the longitude kind of doesn't change.

Even if it was a political decision, as answered on sibling comment, moving east at least makes some sense for the common person.

[–] wongarsu 22 hours ago

Moving time "east" of our actual timezone is pretty appealing to me because of how evening-heavy standard schedules have gotten. The sun might behave symmetrically around 12:00, but most people don't get up at 4:00 and go to bed at 20:00. Most people's days are shifted 2-4 hours to the evening compared to that symmetric schedule, which makes sunlight in the evening more useful than it is in the morning

[–] bryanlarsen 19 hours ago

That's natural. Without clocks and artificial light humans wake up with the sun and gather around the campfire when the sun goes down.

[–] tedodor 22 hours ago

I would rather stay on permanent summer time and give up one hour of sun in the morning for one more hour of sunlight in the afternoon, even if it places us "wrong" geographically. The recent change from summer to winter time was brutal moving the sunset from 17:30 to 16:30, meaning it's dark when going home from work.

[–] matwood 22 hours ago

Maybe I’m an outlier, but I’d rather it stay light later. Sunset at 16:30 in the winter is horrible and depressing IMO.

[–] Thlom 21 hours ago

By end of year the sun comes up around 10 here. If we were on permanent summer time it wouldn't come up until 11. But at least the sun wouldn't set until 16:00 instead of 15:00 as it does now in December. :D

[–] Yizahi 18 hours ago

It is not weird when the standard is either outdated or meaningless. Why exactly a sun high point "must" match precisely 12:00 mark? Literally no one needs that precise match for any valid reason (if it were the case then DST would be impossible, and it is obviously just fine).

[–] sdevonoes 19 hours ago

Yeah but the sun would set later in the evening. That’s a nice tradeoff

[–] fossilwater 21 hours ago

Every summer, DST destroys my sleep. I find it hard to get into "sleep mode" when there is still some sunlight at 22:30

[–] watwut 19 hours ago

I dont care when it goes up. What sux is that it goes down too soon. I would gladly take a shift where it goes up later if I get to have more sun afternoon.

[–] karlosvomacka 22 hours ago

> In winter the sun wouldn't come up until 9:30.

Much better than having sunset before 16:00.

[–] nkmnz 22 hours ago

P.S.: it's not even a question of personal preference. It's a question of scientific evidence. Even if you don't believe that most of these benefits apply to most people, you're free to bring evidence about the benefits of early-evening light exposure...

Evidence-backed benefits of morning light exposure:

Advances the circadian clock, helping shift the body's biological night earlier. Randomized controlled study: https://pubmed.ncbi.nlm.nih.gov/24179293/

Promotes earlier sleep timing and may improve subjective sleep quality. Systematic review of 45 studies: https://pubmed.ncbi.nlm.nih.gov/30670164/

Improves alertness, attention, and reaction times, although average effects are small. 2025 systematic review and meta-analysis of 150 studies involving 5,401 participants (daytime light, not exclusively morning): https://doi.org/10.1080/15502724.2025.2493669

Helps treat seasonal depression (SAD). Systematic review and network meta-analysis of 17 randomized trials involving 773 patients: https://pubmed.ncbi.nlm.nih.gov/40629637/

Can improve outcomes in nonseasonal depression when bright-light therapy is added to treatment. 2024 meta-analysis of 11 randomized trials involving 858 patients: https://pubmed.ncbi.nlm.nih.gov/39356500/

Natural daylight exposure helps synchronize the biological clock with the solar day. Experimental research found that exposure to natural light-dark cycles advanced circadian timing compared with modern indoor lighting environments: https://pubmed.ncbi.nlm.nih.gov/23910656/

[–] watwut 18 hours ago

There is no morning light exposure either way. Seriously. You are talking about "scientific evidence" from completely different time zone with completely different light conditions and completely different lifestyles. There are multiple hours of dark between sunset and going to sleep in the winter anyway. You are waking up into dark and going to school/work anyway.

And only very few people are like leisure or outside sport activities in the morning before going to school or work. It is just not that relaxing when you have to watch the clock or take longer shower after.

[–] nkmnz 12 hours ago

> You are waking up into dark and going to school/work anyway.

You're spot on. Now change the problem, not the symptom.

[–] nkmnz 22 hours ago

Depends on your personal preference. It's ridiculous that the politic topic is the question "should most of us suffer in the morning or should most of us suffer in evening", instead of "how could we allow for more flexible individual schedules", especially when it comes to school, opening hours of public services, and store hours.

How, specifically, would you solve for "just show up like, whenever you want" for kids in school?

[–] simonra 12 hours ago

School is where we show people that society will sacrifice them for others without consideration. So it would be on brand and efficient to let it be up to the parents convenience. And now that it's said that large swathes of employment will be displaced by language models, surely there will be enough manpower going around to have two or three shifts of teachers?

[–] nkmnz 12 hours ago

Exactly like that. Open office hours from the current start of school (Ts) -2h with supervision, self study, project work. Then regular classes from Ts +2h until the current end of school (Te) -2h, with the same offering of study time until T2 +2h. Total time in school can be reduced by 2h or increased by 2h compared to today, based on grades. Of course it will cost money. But don't get me started on the cost of having many children not fulfilling their academic potential because they are tired due to biological incompatibility with the Prussian ideal of the morning person. And now let's speak about childhood depression... or about the fact that 60% of ADHD diagnoses amongst teens vanish once their sleep is fixed.

[–] flohofwoe 22 hours ago

[–] flohofwoe 17 hours ago

How early it gets dark in winter depends on how far up north you are of course. On my latitude (Germany) it gets dark around 4:30pm and 5:30pm in winter, which for me is late afternoon (6:00pm would then be early evening)

I think there is also an issue with Ireland needing to stay in the same time zone as Northern Ireland.

[–] bloak 20 hours ago

That's right. I think for political reasons Northern Ireland has to have the same time as Ireland and the same time as Britain.

And Scotland has to have GMT in the winter so that school children don't have to walk to school in the dark. (Suffering and deaths were caused when they experimentally tried UTC+1 in the Scottish winter.)

Therefore, if you want to get rid of clock changes it really has to be GMT for the whole of the British Isles. I think that would work for me. But I'd rather stick with the current system than make any other change, like UTC+1 all year or Britain different from Ireland.

[–] ninalanyon 20 hours ago

> Scotland has to have GMT in the winter so that school children don't have to walk to school in the dark.

This gets brought up every time the discussion happens, yet we manage perfectly well even further north here in Norway.

Also why should people need government permission to vary the time at which they do things?

As far as I'm concerned I just want the clock to not change every spring and autumn. Institutions can surely be left to decide for themselves what working hours they have? After all shops, cafes, restaurants, bars, etc., already do that.

[–] Hamuko 19 hours ago

>This gets brought up every time the discussion happens, yet we manage perfectly well even further north here in Norway.

Yeah, try going to school in Lapland. If school starts at 09:00, you're walking to school in the dark. If school ends at 14:00, you're walking home in the dark.

[–] Someone 22 hours ago

> and others (north europe) want to stay on their solar time.

Closer to their solar time, for quite a few. As an extreme example, most of Spain lies West of the prime meridian (some parts of it even west of Great Britain, the island), but its time zone is an hour ahead of that of London.

[–] mantas 21 hours ago

But does solar time matters nowadays? In modern day-to-day life noon is not 12:00. People wake up at 5-6-7. And go to bed at 10-11-12. Even for early risers, middle of the day is well past 12:00. Having DST time makes solar mid-day closer to factual mid-day. I'd even argue to for +2 hours DST :D

[–] _ph_ 21 hours ago

Yes, solar time matters as your biological rhythm depends on it. The most important part of it being able to have daylight when you either rise in the morning or at least have the sun get up quickly after that. Another important point is, that there is plenty of experimental evidence that shows that starting schools before the pupils are really awake is not effective.

It is a misconception, that "noon" is the middle point of your awake time. That was never the case. Our day usage most of the time is asymmetric: start the day and especially the work with the sunlight, spend the evening time off after work after sun set.

Using the high point of the sun as the reference for the daytime is a very practical choice, as this is the one easily observable time point which doesn't move much over the course of the year (a few minutes, but that is symmetric).

[–] 1718627440 14 hours ago

If solar time does not matter, why do you care about at when number you get up, go to work, come back and get back to sleep? This would be even more ridiculous. People care about the time, because it's a proxy for sun.

[–] DocTomoe 21 hours ago

IT matters when you have an economic zone in which some have 9am being 'basically mid-day', while the others have '9am being 'oh, the sun just went up'.

This traditionally has been solved in two ways:

1. do the split and accept that you will have costs associated with different time zones and sleep/wake cycles in your population (e.g.: USA / Soviet Russia)

2. don't do the split, and have the cost by putting a time/light adjustment burden on the population (e.g.: PRC, European Union)

My preferred solution would be to abandon all time zones and use something like UTC, or yet better: .beat / Biel Mean Time [1], which does not come with a 'oh, 12 means midday' penalty.

> My preferred solution would be to abandon all time zones and use something like UTC

Which means that

a) textual time references in stories would stop working unless also specifying a location, which would cause a lot of weirdness, especially in fiction

b) perhaps more importantly for day-to-day life, it causes a lot of weirdness around the change of the calendar day and the weekday. It's a rather useful property of the current system that the change of calendar day happens at a time when most people are asleep or otherwise not too fussed about the exact calendar date.

If you completely abolish time zones, that means that for everybody not lucky enough to live near wherever the meridian ends up (which would always be a significant fraction of the world's population, no matter where you'd place the meridian), the change of calendar date would happen during the middle of the waking hours, which causes a lot of weirdness (do public holidays now actually start and stop in the middle of the working day?) and makes date references vastly more cumbersome because a single calendar date can now refer to both solar n in the afternoon/evening and solar date n+1 in the morning.

So you'd have to start using rather awkward double dates for referring to a certain solar day ("the event will take place from the 22/23rd to the 24/25th", "see you on Thursday/Friday" [which isn't the same thing as "see you on Thursday or Friday" today, because that'd become "see you on Thursday/Friday or Friday/Saturday" under the new system properly]), or else develop some convention based on the local solar noon/midnight, which is basically reintroducing time zones through the back door.

[–] DocTomoe 14 hours ago

That only is a problem if you don't separate the 'time number' from the observed local time.

You could easily have a 'multiple calendar days during one solarday' situation. In fact, many countries already do this for their TV programming, in which a show might screen on "Thursday at 23:55 until 03:15".

For common things, you could just refer to as 'tomorrow morning'. If you need more precision, you can fall back to .beats. "School starts @740" Incidentally, that's exactly why I liked .beats: no false associations.

Why do we all need to have the same time? And if we do, we should just use UTC around the globe.

[–] mantas 21 hours ago

It's more complex than north vs south.

I'm quite north (but not the far north) but I'm strongly for DST. If we went for solar time, we'd loose long bright evenings in the summer but have sun at 3am. Spring/fall evenings would be much darker too. I hate time switching. But I'd rather switch then loose DST summer evenings. Otherwise we'd loose a lot of outdoorsy socialising on weekdays

But some people don't go outdoors after work. And they prefer brighter mornings for couple extra weeks. During the winter the mornings are dark with or without DST.

[–] _ph_ 21 hours ago

Well, actually not. What was voted on was the plan to end the DST shift. The reason it stalled on was, that there was no decision about how exactly to end the shift.

In my personal opinion, the only reasonable decision would be to permanently return to the standard time before the introduction of DST. Because otherwise the whole European timezone would have to be redesigned.

[–] input_sh 21 hours ago

It'd never happen of course, but I'm of an opinion that a very simple compromise would be to switch it by half an hour once and stop this "who's gonna decide on which zone" nonsense that's been dragging on for almost a decade.

[–] _ph_ 21 hours ago

I don't think this would be a good choice. The current setup of the European time zones works very well, it has been decided upon a long time ago, based on geography, the local connections. All arguments point either to returning to the standard time or keep the clock change twice a year.

Sunset isn't changed by DST. You adjust your schedule. You're free to do so on your own terms, without the government forcing everyone to do the same shift at the same time for the same amount of time.

[–] maratc 21 hours ago

It only works when you don't have children (kindergartens and schools start at 8) or spouse (who can have a different schedule) or office work (so you don't have to be at the office at 9.)

Time has stopped being an astronomical fact, and is a social contract nowadays. It's possible that you can afford to opt out of that contract, but most people can't.

[–] nkmnz 21 hours ago

That's mostly true(*), and we should work on making the opt-out a standard procedure where ever possible.

Instead, the public discourse centers around which minority can force the majority to follow their preferred terms in the social contract. At best, it's a zero sum game - most likely, it's a net loss for everyone if we include all externalities, especially the suppression of discussions about more individuality.

(*) DST is not a social contract, it's entirely made up by the law.

[–] maratc 21 hours ago

You can take it in any direction you want, but I have pretty low expectations of schools willing to teach my kids from 10 to 16, or mechanics willing to fix my car at 20, or doctors willing to take my blood exam at 22 — all that just because that would be convenient for me.

The modern society started with the Industrial Revolution, when the people understood that there are some very tangible benefits when everyone starts working at the same hour, and started building around that. This building included discarding "local time" (an astronomical fact) in favour of standard time (social contract.)

[–] OroPla 19 hours ago

> or doctors willing to take my blood exam at 22

There used to be a system in my country where there were large doctor offices and you didn't really have your doctor, as you had your clinic. (I'm not talking hospital, but doctor's office.)

It was staffed around the day. Each doctor had a work life balance and you could come in whenever. I'm pretty sure this approach works for most service professions.

School can be transitioned to be purely online. Watch video lectures when you want and take online tests regularly. There is really no point to lock all kids up at school for hours each day if the goal is merely to teach them. People leave school illiterate these days, so it's not like it could get any worse.

[–] ninalanyon 19 hours ago

But not everyone does start working at the same hour. I went to a supermarket today that opens at 07:00 and closes at 23:00, a cafe that opened at 10:00 and closes at 18:00, and a charity shop that opened at 12:00 and closes at 16:00.

When I was working I worked from 08:00 to 16:00 with a half hour break for lunch. But several of my colleagues in the same office worked 07:00 to 15:00. All of us worked with other engineers in countries across the world. My children went to school at 08:30 until 13:30 until they were in senior high school when it was 08:00 to 15:30

The local buses start running at 05:30 and stop at 22:30.

[–] TheOtherHobbes 19 hours ago

It would be possible to split the day into shifts and have the night owls providing services for other night owls.

Medical emergency cover is 24 hours already. Some factories run 24 hours. So do some transport networks.

There would be huge benefits for commuting because traffic would be spread out.

The practical issues have more to do with noise and energy use, not the "social contract."

[–] maratc 19 hours ago

Most working adults are also parents, and so their working hours are wrapped around the daycare hours.

In any case, you’re talking about a societal change which is much broader than just a clock-setting issue.

[–] nkmnz 12 hours ago

> there are some very tangible benefits when everyone starts working at the same hour

This must come from an office worker, dropping their child off at school or day care at 8, doing some chores until 9, starting work at 9:30 - or something like that. I suggest you take the bus or the metro once at 5 in the morning. You'll see plenty of people going to work. Maybe it's a local thing, but public services in Germany often start at 6 so that they can finish work before citizens start calling (and so that they can leave early and benefit from everything else still being open).

Also, there are mechanics that fix my car in the middle of the night when it breaks down – but I have to pay a membership fee, otherwise, it would be unaffordable. There are also plenty of doctors willing to work a night shift, but since we have socialist health care in Germany, it's difficult to pay them a premium - so that leaves those who triage by acuteness, not by price.

[–] maratc 9 hours ago

> I suggest you take the bus or the metro once at 5 in the morning.

In order to do that I would need to drop the kids at 4:50 at the (closed) doors of the school, and it will end very badly very quickly.

Imo the obsession with "solar/astronomic" time is weird. I kinda get the reason - a) we humans hate any change, b) we humans reaaaally like pretty and symmetric concepts. By why exactly it is "a must" that high point of the sun matched with 12:00 precisely? Who cares about that for a valid reason instead of tradition and fear? Why not match it with 11:00 or 13:00 or literally any time point?

Countries have long singe transitioned from the rural lifestyle and should adjust life and healthcare conditions for a majority, not for minority. A majority of population should get as much daylight as possible, for the best long-term health outcomes.

It should be a pretty simple and easy task for professional statisticians. Compile average outside time for every age and every job cohort, overlay them and we will get a nice graph with two nice normal deviation peaks - morning and evening. Then shift a daylight graph (which would be a single very wide "peak" of sorts) overlaid over that outside time graph by adjusting timezone point/center. Play with it until the area matching on both graphs is maximized and bingo - that's the optimal timezone for a majority of population.

I suspect with AI help it can be done in a week by a tiny team, instead of years and decades of baseless shouting and finger pointing and name calling in press, parliament and random social networks.

[–] rayiner 18 hours ago

It's actually extremely logical. It makes sense to line up the day with the actual sunlight hours at any given time. But people have millions of events keyed to specific times.

I'd fight tooth and nail for them not to take an hour of sunlight from me during summer evenings.

It is not roughly the same if the sun rises an hour earlier instead, at 04:30 instead of 05:30.

I'm curious how disruptive this would be from a database perspective ? For eg, All the flight bookings to/from Cuba needs to be updated because it would have originally accounted for DST.

[–] williamdclt 21 hours ago

If application engineers did their job correctly, they have nothing to update because you should store future events as a wall clock time + timezone, not an instant (ie something like `2026-09-01T09:00:00, America/Havana`, not `2026-09-01T09:00:00-05.00`).

Which means that flight booking systems are _probably_ fine (they're probably the domain that cares most about timezones and time changes so they've probably modelled it right), but many systems are not fine because it's such a common thing to get wrong.

[–] pwagland 20 hours ago

But that is _exactly_ the problem.

Flights take x hours in the sky, and so would have left at `2026-10-01T09:00:00, America/Havana`, and arrives at Miami at `2026-10-01T10:25:00, America/Havana`.

Now, they have to choose, do they arrive at 10:25, and leave at 10:00? Or do they leave at 9:00, and arrive at 9:25, since only _one_ of those two timezones is changing. It is extraordinarily unlikely that they'll choose to just circle in the air for an hour so that they can just keep the same departure and arrival times.

[–] jprjr_ 20 hours ago

I'd imagine the choice is driven by a whole lot of factors like which is the busier airport. It's probably easier to adjust the Cuba departure than the Miami arrival.

It's kind of like how some parts of the country should really be in a different time zone but they keep in sync with a nearby, bigger city. I'd imagine the smaller airports/airlines just say "yeah your Cuba flight is leaving an hour later so we stay in sync with Miami"

[–] williamdclt 16 hours ago

Ah, good point, I spoke too quickly (will I ever not fuck up anything that involves timezones...)

I'd guess that the Cuba side changes, so that all changes are localised to one airport, which is probably much easier than changes at every destination airport

[–] jprjr_ 19 hours ago

Going with UTC doesn't work all that well.

Time zones give a rough idea of where the sun is and whether people are more likely to be asleep or not.

Like I know if I schedule a meeting at 8am in New York, that's 5am in California so I'm unlikely get people from California to attend. Or at least it's pretty rude of me to expect people in California to attend

If I schedule a meeting at 12 UTC - that gives no indication of where the sun is in New York or California (or anywhere).

The fact is people tend to do things with the sun is up and sleep when it's down. Time zones are a compromise so your clock is still kind of in sync with the sun while still being able to synchronize with larger areas.

[–] OroPla 19 hours ago

Not sure what the position of the sun has to do with when people work. If you schedule a meeting with me before 11am, I probably won't make it, since I'm still sleeping. You can schedule a meeting with me at 11pm if you want, though.

A very useful property of the current system is that calendar days are aligned with solar days and the change of calender date consequently happens when most of the population is either asleep or otherwise not too fussed about the exact date.

UTC-only (or equivalent "global time" proposals) breaks that for everybody not living near wherever the meridian ends up, which causes a lot of weirdness when a single calendar date can suddenly refer to two completely different solar days and two completely different wake cycles.

Additionally, such a proposal would also break all clock time references in fiction, especially when reading works set abroad or in some unspecified (but still Earth-like) setting, but I guess if you don't care about the calendar date weirdness, you wouldn't care about that, either…

[–] WinstonSmith84 12 hours ago

It's very approximate. You've Spain which has almost +3 hours of offset in the west of the country with the sun during DST, while you have countries like Japan which are in the negative territory (Tokyo).

[–] jillesvangurp 21 hours ago

I wouldn't mind either. But I do see the point of different countries wanting to be in different time zones. I live in Berlin. My parents are in the Netherlands. We're in the same timezone but there's a good 30-40 minute difference between when we have our sunrise and sunset. Very noticeable when you do a video call around that time. I'll be sitting in the dark and it's still light on their side. The central European timezone spans from Spain in the west to Poland in the East. that's roughly 9 degrees west longitude to 24 east. A normal timezone should be about 15 degrees (360/24), not 33. That's more than two hours difference between when the sun sets/rises from east to west.

So, I can see that how some countries like Spain and Poland might want to make different choices when it comes to losing or keeping the hour permanently as Spain is basically in the wrong timezone. If you want to have noon occur when the sun is highest in the sky, you need to be close to 15 degrees east (roughly the Polish border with Germany).

Much of Spain is technically west of Greenwich (0 degrees longitude). Which means it should be GMT. You could make the same argument about France and the Netherlands being closer to Greenwich than the Polish border with Germany. I'm at 13 degrees east in Berlin, so pretty close.

Countries further north tend to care less about this because most of the year it's either too dark or too light most of the time. I used to live in Sweden and Finland. Daylight saving doesn't do anything useful there. There's not much to save when sunrise is just before noon in the winter and shortly after midnight in the summer. In Helsinki (not in the same timezone), the sun is already rising around 2am in the summer and it's still dark at 10am in the winter.

So e.g. putting Scandinavia in UTC +1 and Spain and Italy in UTC +2. Where we draw the line is tricky, because I doubt that nether France or Germany would want two timezones.

There absolutely is. The north is getting very little sun in the winter (about 6 hours) and very much in the summer (about 19 hours), while the south has a lot less variance (10 vs 14 hrs for south of Spain.) My argument would be that the south needs DST more than the north.

I understood that and I genuinely sympathise with the daylight-related syndromes people up there in the North have to deal with, but you also have to understand that further South we also become depressed if the Sun comes down too early, especially in the summer. So from an utility and democracy point of view the wellbeing of the majority (and the vote of said majority) should take prevalence over the wellbeing of the minority.

Or you know, you could just put countries in different timezones. Apparently that's easier than convincing people that the workday doesn't need to start at 8:00 (or 10:00 in the case of many in Southern Europe).

Because it's generally senseless, and particularly for them even more so given their location.

[–] oddIdentities 22 hours ago

Because DST is the wrong time; if you look at the legal implementation of DST, most countries carve out exceptions for fields where lying about the time can obviously lead to death and destruction - navigation being perhaps the main one.

What everyone missed is that DST could itself lead to much greater loss of life than we might have lost had the use of DST been mandated all the way through to e.g. large naval, air or spacecraft.

And as research into DST continues, this seems to have been not merely an abstract possibility was missed, but _the actual outcome_. DST is quite literally killing people by the thousands.

I hate daylight saving time or summer time or whatever. Can't we all just have normal time all around the year?

I have totally solved all issues. I have additional pointer on my watchface for the true position of the sun. https://photos.app.goo.gl/M95bW4XWR2NDUup46

[–] maratc 20 hours ago

You haven't "solved" anything, as the position of the sun is not more relevant to the modern lifestyle than the phase of the moon. It's "good to know" I guess but solves no actual issue.

[–] timonoko 19 hours ago

It is your lifestyle son. I don't care what-o-clock it is. I just try to stay awake when sun is up. In northern latitudes it is vitally important, they say. Or rather youtube-doctor Andrew Huberman says.

[–] maratc 19 hours ago

Not sure why you're wearing a watch then? You can just look outside.

I need a watch because the kids start school at 8, so they need to be up at 7. This is true whether the sun is already up (June) or not (December.)

[–] notabotiswear 20 hours ago

Eh. Sudan has had a de-facto, _permenant_ DST from 2000 to 2017. Had absolutely no effect iirc save for the expected confusion in the first few months, especially considering that the change was made in winter.

[–] steveBK123 13 hours ago

My proposal has always been that we adjust the length of an hour so that the sun always rises/sets at the same time. /s

Yehh Europe is loosing its mind..

I belive this whole clock fliopity flip twice a year is a huge contributing factor to people's "unbalance", and worsening mental state... Especially the northern parts....

We humans are creatures of habit... Mess with the circadian rhythm of en entire population and expect no adverse effect.... Mhm checks out.

[–] GuB-42 20 hours ago

The thing is: everyone has an opinion, but the scientific evidence that one system is better than another is weak.

And it is weak because people are different. Some people tolerate clock change better than others, some people function better in summer time, others function better in winter time. Any decision you make (keep clock change, summer time only, winter time only) will benefit some people and will hurt others. And there is not even strong evidence that one solution is better on average.

For the disruption caused by clock change itself, it is indeed noticeable, like an increase in traffic accidents, but it is just one day, but the effect of being in summer time vs winter time lasts 6 months. So if the clock change makes even a small improvement for 6 months, it may be worth the disruption for 2 days a year. I am not saying there is, it is just that there is no real consensus.

So, by default, when a change may have negative consequence for some people and may not lead to an overall improvement, you don't change.

"Days" is plenty of time, IIRC some tz changes happened hours before they had to come into effect!

Most of the world is the voice of reason actually.

This is a very European / North American problem for some reason. There are some exceptions, but in general Asia, Africa and South America don't do this.

[–] gonzus 21 hours ago

If you mean "changing time in summer", Chile has been doing this for a while, and I think other countries in South America do to.

If you mean "changing the rules a few hours / days before they should be applied", Chile (again) did this a few years / decades ago, and it wreaked havoc: all scheduled meetings were off by one or two hours, you could not rely on your calendar, etc.

Plenty of stupidity going around in Chile / South America, rest assured.

[–] input_sh 20 hours ago

> and I think other countries in South America do to

Nope, only Chile, and not even the whole Chile. Similarly, Egypt is the only exception in Africa, Lebanon/Palestine/Israel are the only exceptions in Asia, plus also New Zealand and like half of Australia.

The vast, vast majority of the world including China, India, Mexico, Russia, Iran, Turkey and so on don't move their clocks. In fact, out of 20 most populous countries in the world, only three do: United States, Egypt and Germany.

The EU again is all talk and no action on this topic. 84% said in a poll to get rid of it back in 2018, parliament voted to end it by 2021. But here we are at the end of 2026 turning the clocks back again. Next march same thing. Honestly at this point I don't think it will ever happen, they will still be "discussing"it in 2040.

[–] leipert 22 hours ago

Actually “only” Germany voted back then. Like 3.79% of Germans voted. So that comes out to ~3.18M of 4.6M votes cast by Germans.

A vote was held and a conclusion reached. Voting is not mandatory, but generally the outcome of a vote should be followed.

I voted to permanently abolish daylight saving time/summer time and am very unhappy that it isn't gone already.

[–] _ph_ 18 hours ago

So much confusion about this. There was never a "vote" about it. It was more like a poll, which wasn't advertised across the EU, and on top of it was severely plagued by server failures. To have a binding vote:

- it needs to be properly announced to all eligible voters

- be declared as binding, you can't tell people it isn't a vote and later on declare it is

- the platform for voting needs to work

[–] jansan 18 hours ago

Who cares? On 26 March 2019 the European Parliament voted 410 to 192 in favor of dropping the DST requirement in the EU by 2021.

Nothing happend. All talk, no action, as I wrote above.

[–] _ph_ 15 hours ago

Unfortunately, they left open what happens after dropping DST. If they had clearly written that the EU would return to the standard time, it would have been active back then.

How would something that has been in effect for at least 60 years still lead to a worsening mental state over time?

Yeah, because humans existed for only 60 years.

[–] echoangle 22 hours ago

Well most people haven't existed for 60 years. Where I'm from, DST was introduced 110 years ago and people still complain. When will the worsening mental state reach equilibrium? Or is there maybe a chance that the worsening mental state isn't due to DST?

Sure, but hasn’t that been the case for all the time since DST was introduced? The original comment to me sounded like DST is responsible for people being in a worse mental state now than a few years ago.
