Nah, it also sounds terrible on paper.

I'll correct myself: it sounds good for about 5 seconds before you think about it and realize it's an unworkable idea which creates more problems than it solves.

I have all my clocks set to UTC. Works for me

That's a myth. Farmers have to wake up early because their animals wake up at sunrise and some tasks are best performed at that time. So they wake up before sunrise regardless of the clock time. Human, like farm animals, are better off if they wake up at sunrise and go to sleep in full dark. At the equator that's easy, wake at 6, bed at 10PM. And standard work hours are 7-3 or 8-4.

So, it sounds like you're actually arguing that the numbers are just a construct and that we should all just use UTC and set appropriate work hours to the times that most correlate to the solar day in our region rather than adjust the clock approximately 1 hour per 15 degrees around the equator and have an International Date Line. I think this would make way more sense, when they say the Olympic Opening Ceremony star…

Yes.

No. that does not follow. Abstraction is useful. Having commonly understood terms (in this case hours of the day) that share certain traits regardless of where you happen to be in the world facilitates communication.

I'm in BC. The astro-nerd in me would have preferred to see permanent Standard Time instead of a permanent +1 offset. Instinctively, I think morning light is important to our biology for a daily reset and the solar cue of "high noon" is also a real thing. I'm sure I've read that sleep health experts have historically supported a change to permanent Standard Time, not DST. I respect there are economic arguments for pe…

I've seen arguments about kids going to school in the darkness being thrown around a lot, but I've never understood why that (against fresh drivers) is always taken to be worse than kids coming home in the darkness (against exhausted drivers).

I agree with you. I also need to shout at the clouds on this because the experts who make the argument for time changes drive me crazy.

I live in Calgary. At a previous grade school my daughter went to, school started early enough that she left in pitch black conditions in winter, regardless of "experts" and their precious daylight savings time.

'You need sunshine when you wake up' is really a ridiculous argument, there is no sunshine even with DST.

Get rid of it. Maybe egg the houses of the "experts" too.

(As for my kids, thankfully, they did remote school during Covid (hence late mornings) and then I moved to a place where the school starting time was later than 8.)

Thankfully, this is a situation we don't need to speculate about without evidence. Spain is on de facto permanent DST, serving as a natural experiment. I bet the results support you.

So would the folks who study circadian rhythms:

> Over much of the highly-populated areas of Canada, the sun would not rise until about 9 am in winter under DST, and the daylight will linger an hour later in summer evenings than under Standard Time. As a Northern country, Canada includes higher latitudes where the effects of late winter dawns and late summer dusks under DST would be felt more profoundly. What long-term effects on health can we expect from year-round DST? As predicted from our understanding of the human biological clock, our brain clock will try to synchronize to dawn and push us to go to bed later. However, our social clock will force us to wake an hour earlier in the morning. Will this have any health effects?

> We have good evidence for the negative impact of being an hour off of biological time, and this comes from studies on the health of populations living on the edges of time zones. We have arbitrarily divided the earth into one-hour time zones, so that people on the east side of a time zone see the sun rise an hour earlier (according to their social clocks) than people on the west side of the same time zone. Researchers have analyzed the health records and economic status of those two populations, and have found poorer health outcomes on the west side: increased rates of obesity and diabetes, heart disease, and cancer (Gu et al., 2017). Moreover, people on the west sides of time zones earned 3% less in per capita income (Giuntella and Mazzonna, 2019). What could account for this? As predicted, people on the west sides of time zones go to bed later than people on the east sides, but then have to get up at the same time in the morning because of fixed work and school schedules. Therefore they lose sleep: about 20 minutes per weeknight, which adds up to a significant sleep debt over the week. We know from other research that sleep deprivation negatively impacts health and workplace performance. We can already see the negative impacts of a one-hour difference across a time zone, and year-round DST would put our social clocks another hour out of alignment with our biological clocks.

Reminder that a few hundred years ago when clocks were oddities we didn't have to deal with any of this madness because everybody used True Solar Time as a sundial would read it. What time do kids go to school? After the sun rises. Simple. Now that we have clocks it suddenly becomes difficult to schedule simple things like sending kids to school in sunlight.

In germany the terms are Sommerzeit (summer time) and Winterzeit (winter time). Of course everybody would chose the former as summer sound better than winter but the latter is "better" as it corresponds more to "wake up when there is light" which is favorable to health, performance etc.

That's a very dishonest take, as I'm sure you know that Sommerzeit proponents have reasons other than "summer sounds better than winter".

For example most people just wake up and go to work in the morning, but in the evening they meet friends, BBQ, hike/run through nature, do sports etc., and prefer doing those activities while it's bright outside.

It's not just a measure for the state of sun in the sky, it's also a measure for the state of society on the ground. It's an arbitrary number in a sense, but it also strongly influences my schedule. And yes, we could have all the schools and everything else open later in the winter than the rest of the year, but it turns out it's easier to change the clocks.

But the school schedule does already shift and it shifts later, so in the opposite direction. The policy trend is going in the opposite of what you want to achieve with year-long DST, you could instead vote for the status quo and have the same effect.

Do BC schools have a different winter schedule? That's not how it is where I live, at least. It seems like it would be pretty annoying to have to reschedule activities around getting to/from school twice a year.

Why now? From the Govt of BC press release: "The Interpretation Amendment Act, which is the legal framework that enables the Province to adopt permanent DST, became law in 2019. At the time, government chose not to bring it into force in order to co-ordinate timing with neighbouring U.S. states in the same time zone. Recent actions from the U.S. have shifted how B.C. approaches decisions that merit alignment, includi…

Notably Washington state legislated the same change to DST years ago (instead of standard time, the morons!) but the federal government never approved the switch. AFAIK it's still pending. I remain unclear what authority the federal government has over such a matter and why Washington (or any other) state has opted to respect it. What are they going to do if a state just ignores them and switches their clocks?

Sometimes I get the impression that the spirit of states rights in the US has died.
