Plenty of countries have moved away from DST. Over half who previously used it IIRC.

Please name some of these countries. Europe is stuck with this nonsense and there is no hope in sight despite yearly polls showing majority people being against it.

Do the anti-DST people understand what they're advocating for? Have a look at the sunset/sunrise graph for northern parts of the US https://www.timeanddate.com/sun/usa/seattle In Seattle, without DST, sunrise happens at 4:11am. Because of DST, it's pushed back an hour later to a more reasonable 5:11am. I am not awake at 4am, I have no use for sunlight at 4am, and I don't want the sun appearing that early. That hour o…

You can have your own household clock.

Are you Yanks seriously not going to get this sorted out before winter? BC has moved - can at least the rest of Cascadia get their asses in gear? Come on, California, I do not want to be dealing with a north-south time zone difference with my coworkers

We don’t really get much of anything sorted these days.

This just seems like a backwards justification. There is nothing wrong with a 9am sunrise or a 4:11am sunrise. People in Anchorage deal with both just fine. > I am not awake at 4am, I have no use for sunlight at 4am Most people aren’t awake at 5am either. Your use for the sun when there is an excess of it that goes well past your bedtime if you get up at 5am is irrelevant.

My work starts at 9am, therefore I wake up around 7am. My work start time does not adjust based on the seasons. Any sun before 7am is wasted for me. Under DST, at summer solstice, the sun rises around 5am, giving me 2 hours of wasted sunlight. Without DST, at summer solstice, the sun rises around 4am, giving me 3 hours of wasted sunlight. I enjoy having additional hours of sunlight when I am awake, so for me I actual…

I still don't understand why you don't just wake up earlier.

It's not like without DST you have to work so late that you don't have enough hours for sleep, right?

Queensland Australia, a single state moved away from it. It is glorious.

https://www.timeanddate.com/sun/australia/brisbane Queensland Australia is relatively close to the equator, and the length of day does not change dramatically between summer and winter. DST is intended for places at higher latitudes.

No, it is intended for a small band of places where the latitude is big enough to make winter and summer daytime length significantly different, but not so different that DST does nothing. In Sweden, with DST, the sunrise is at 4am in summer and 8am in winter. Just set it so noon is actually noon.

Between this and the "Sunset time and the economic effects of social jetlag: evidence from US time zone borders" paper [0], it seems like the issue is the size of the discontinuous jump in time, not necessarily that we change the clocks. So why not "smear" the DST ST transitions by having four half hour transitions, once each quarter? [0] https://pubmed.ncbi.nlm.nih.gov/31030116/

If you present this as the alternative, I think there's a chance people might actually just get rid of it :)

I like where this is heading.

To that end, I'd like to propose 12 transitions. These should happen on the 16th day of every month, at precisely 05:14:33.

Let's take our seasonality more seriously.

You've said this repeatedly, but it is largely not true.

My controversial idea: midnight should be where current 4AM is because 04:00 is the lowest point of human circadian rhythm. Currently we have nonsense like "1AM is technically a part of the next day but for all practical purposes it's still the previous day". Also, 24h clock should be the standard so that we can avoid discussions "is 12AM noon or midnight".

Why should the clock be set to those arbitrary points? If you want sun in the morning, wake up later, it you want sun in the evening, wake up earlier. If your issue is when work is scheduled, well businesses set their own hours, not the government.

Working hours will not change. I will fight tooth and nail against attempts to take one hour of daylight from me in the evenings for half of the year.

"Working hours will not change". Except they have in most countries where they have got rid of DST...
