This articles mentions that Cuba tried permanent DST in 2004-06. This makes me wonder, has anyone ever tried permanent DST 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.
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.
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.
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.
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.
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 when it gets dark earlier in the evening. 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.
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
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.
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.
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:
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/
> 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.
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
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.
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.
I hate DST switching, and since last 3 days I've tried to live as if DST didn't happen, go to sleep super early etc.
It completely fails when you account for everyone else around you. Could work if you live alone with flexible working hours. But having a semi-active social life and kids makes it impossible.
> Every single time adjustment (or jet lag) is a drama for me
As a counter-point, I personally don't even notice it. Also, I live in Romania, so every trip West of the border, even just to Hungary, means a one-hour change, so, again, no big deal.
Yeah same here, I don't even noticed the time switch this time. I remember it was worse as teenager, so maybe it affects young people more than old farts ;)
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.
well https://www.iana.org/time-zones/releases/2026f has the right info. If they stored everything in the DB as UTC... this is like a DNS change. Downstream partners need to have a TTL on it.
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.
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.
That's 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.
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!”
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.
I hope the EU will follow soon. Or at least my home country. Since the EU already has different time zones, the stalling because "all should have the same time" doesn't make sense.
Does anybody what's the status with solar power there? Seems like the country would have plenty of sun to use. I know that some private people in the island are running almost 24x7 on solar and batteries, but most private people, companies and specially the government are still in blackout.
(Unfortunately, it always gets derailed by highly-polarized discussions about whether to stay on DST forever or get rid of it forever. They'll be showing up here again soon enough.)
It is a reasonable take but it is not the _only_ one - I think it is arguably more reasonable to transition away from DST to ordinary "best TZ granularity approximation to zenith-occurs-at-noon" time once, and then stay (and manage) that time over the millenia to come.
But can we... uh... can we keep that as some kind of tertiary issue to solve later after we successfully stop screwing up the clocks twice every year? We don't really need to build a singular omnibus clock overhaul that will most assuredly never come to fruition, do we? :)
This makes sense given all of the power outages largely caused by U.S. sanctions. You would in this scenario want to have more daylight extending into the night time hours.
I don't understand the obsession with keeping the perfectly vertical sun at noon given we all work from dark to dark under winter time. What would actually help us experience daylight would NOT be moving the clocks or moving work an hour earlier or a few hours later
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.
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.
I remember reading somewhere that we see an increased incidence of heart related ailments around the clock change, hypothesized due to this change in sleep patterns.
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.
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?
I don't know it this will be the case for Cuba, as it's somewhat differently placed on the map, but Russia tried DST only and had to switch to standard time and then stayed there.
Some people absolutely loves DST for some reason, but it creates stress and mental problems for people, especially in the north. The long mornings are somehow worse than the short evenings. Technically it shouldn't matter what the clock shows, but when society insists on things happening at a certain time, whether or not the sun is out becomes important.
We don't care about the people living in the North, there are more of us living not in North and as we live in a democracy (the EU) the majority vote should cound on this.
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.

Much better than having sunset before 16:00.
