IMO, having the sun set later is better because it means I get to enjoy a bit more sunlight in the evening, after the work day. But I'm also really not a morning person.
It is the default. That's why it is called Atlantic/Eastern/Central/Mountain/Pacific Standard Time in North America.
(The more legitimate argument is for western regions to align to summer time to be closer in clock time to their eastern neighbors.)
> The light/dark cycle of the sun has a powerful effect on the circadian clock, sleep, and alertness. If you understand these effects, you can manipulate light exposure to help yourself sleep better at night and be more alert during the day. Keep in mind your circadian clock uses light and dark signals to predict what to do in the future: when to prepare you to be active and when to prepare you to sleep.
Noon corresponds to light. Traditional time keeping has been built around light forever for reasons that are still relevant even though we now have plenty of artificial light. There is no reason why we cannot adjust when we work, keep places open, and share waking hours around the sun, but we cannot adjust the sun.
This is the entire point of DST. To adjust when we work, keep places open, and share waking hours around the sun.
> but we cannot adjust the sun.
Of course, but we can adjust the angle of the hour hand on a clock. So we do that.
Perspective may vary here, but it seems to me it's to avoid having to adjust when we work by having the government enforce an artificial aberration on top of the normal social construct of time, a construct that at least hinges on the objective reality of Where The Sun Is. It's to avoid moving "a 9-to-5" to "an 8-to-4", to avoid it by pretending that noon isn't noon and making all of us mess with our clocks to keep up that pretense.
Exactly. In our modern lives, noon itself is not very significant. Sunrise and sunset are much more so. So when the sun starts to set "too early", we fight back by pushing the clocks forward an hour. Some people don't like it because maybe they want the sun to rise earlier. Or maybe they hate the lost hour of sleep. Or they're a distributed database programmer :)
But there's no solution that pleases everyone, so we all get on these long threads about DST twice a year and yell at each other. My preferred timekeeping would have me join the "America/Phoenix" time zone (I'm in California). But 2nd-best is the current system.
Gotta coordinate things like this, otherwise it won't happen.
I think this is really the crux of it, it's just a matter of personal preference and there's no one right answer. When I was younger I used to wake up later and I thought permanent DST was a no-brainer for the extra hour of light in the evenings. Now in my 30's for whatever reason my body clock has shifted a lot and I pretty much always wake up by 6:30 am. The last few weeks with the sun not rising until 7:30 in northern CA have been kind of depressing and I can't wait for DST to end, I'd now rather have that extra hour of light in the morning than the evening.
Ideally, each region would have their summer time adapted to their latitude, but that would be more chaotic than simply scrapping it.
I’ve learned a huge amount of sleep lately and every cell in our bodies is regulated by our circadian rhythms.

The reason we don't all use UTC is because it is useful to be able to figure out roughly what time of day it is somewhere else on the planet. If we collectively agree that is no longer necessary then we are giving up a fundamental part of timekeeping.
If you want an example of how crazy this is, just look to China, which only has a single time zone. It is so large that in some parts of the country the sun doesn't set until "midnight".
Time actually means something, don't mess with it.
And during the Spanish Civil war Republicans had already moved to GMT+1 in 1938, a change that was undone after the war before switching again to GMT+1 in 1940.

That would be great advice for not changing the clock every six months.
Not clear. Those you call «winter hours» are supposed to be the actual, real hours: noon equals zenith, midnight equals nadir. You can have some reasonable exception, but to call "midnight" all year what is not midnight makes no sense. It amounts to "falsehood", where it would be just social agreement to just wake, work, dine sooner or later.
People in Paris know they have a pretty severe offset, ~50m (those in Vigo even ~95m). If you added a sticky +1h, the offset against solar time would increase to ~110m and ~155m.
Chicago has the opposite problem, where it's dark at 4:30pm in the winter.
13 years of rising hours before dawn and walking and waiting in darkness is enough.
I would suggest that the government of any state or nation not be allowed to ever say what [civil] time it is, and require that they take technical timekeeping information--for TAI, UTC, UT1, and the like--from non-political scientific bodies.
I don't really remember waiting for the bus in the dark until I was in high school, when they started earlier and due to the need to use the same bus for later runs to elementary schools, we arrived at school 30 minutes before class started. I'm thinking my elementary school started at 8:30 or 9:00am? But I can't really remember.
