Businesses don’t care how much sun you get

The government doesn't set the opening hours of businesses though either.

The government? Or your government?

Because there are countries where national or state governments do.

So change it... just permanently. GMT+2 will always be there for you.

Then you will have the opposite problem in winter. Sunrises would be 9am-10am for about three months.

> Sunrises would be 9am-10am for about three months.

At least you'd get some sun after work. Here in Norway, the only way to get sunlight during a workday in winter is to go out during lunch break. While I do acknowledge that getting sunlight in the morning is more important than in the afternoon, I feel like subjectively I'd have more use for a little bit more sunlight after work than before work.

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…

They do, which is why only 45 countries observe DST.

25 observe it partially.

And the rest, roughly ~125 countries do not.

Historically, ~140 countries did.

To put this into perspective, only about 1.2B people out of 8.3B observe it today. Which puts you into a very small <15% minority.

That means waking up for work 2-3 hours before sunrise, and starting work before dawn.

I'd very gladly have a more natural sleep schedule than some sun in the afternoon.

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".

I live in a hot desert climate where most of the daytime during summer is inhospitable to human activities.

We also do not observe DST at all, and that makes us a red-headed stepchild in America.

I have longed for a system here where summertime means a 12-hour DST: everyone sleeps all day and then goes to work/school in the coolness and darkness of nighttime. I absolutely love chilling outside in the dark when the lows are in the 70s, 80s.

Time zones were invented because of railroads, and all of the time/date related troubles we have today is because modern urban technology is 100% fake artifice that denies the contours of the natural world, not to mention globalism that denies contours of local culture and seeks to cram everyone and everything into rigidly defined boxes.

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…

You can still wake up earlier and enjoy your sunrise even if your working hours are fixed.

Are you seriously suggesting I wake naturally at sunrise (4 AM), then start work 5 hours(!) later? I can't change my work start time.

That's an unproductive use of my time.

Appealing to population is a stupid argument. DST as a policy is designed for places at higher latitudes, and the the majority of the planet do not live at higher latitudes. DST exists to maintain a more consistent time of sunrise across seasons.

DST is moronic in any part of the world close to the equator. There is not enough seasonal adjustment in the time of sunrise to justify adjusting the clocks. And in places of the world such as the middle east, they have an active policy of avoiding the sun and a policy of DST (which maximizes sunlight while awake) is antithetical to how society functions.

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.

The government sets the hours of the schools, which in turn drives the schedules of a fair chunk of society.

Oh my God, just move it by half an hour permanently!

That doesn't fix anything, the reason DST exists is because at higher latitudes, the sun rises too early in the summer, and too late in the winter. DST exists to make the time of sunrise more consistent across seasons. DST only functions if hours are shifted seasonally, once for summer, and again for winter.

Have a look at a sun graph to understand why https://www.timeanddate.com/sun/usa/seattle
