I guess it's an unpopular opinion on HN, but I like switching back and forth between daylight saving and standard time twice a year. I live relatively north and I like having very long days in the summer when more daylight is available for both the morning and evening. Without DST, the sun would rise at 4am for me in the summer - what on earth am I going to do with that? I'd much rather it rise at 5am, and I get an extra hour in the evening. On the other side permanent DST would be awful in the winter because then the sun wouldn't rise for me until 9am.

Maybe countries and states should choose based on how far north or south they are because that seems to be a key factor for how useful DST is?

But beyond that I don't fully understand all the complaints specifically about changing. It's an hour shift twice a year? Maybe I get slightly worse sleep for a day or two but then I am fine. It's no different than changing one time zone while traveling. People travel all the time cross country or over the Atlantic or Pacific and that's a much bigger shift in time yet they're all able to cope? I don't see articles regularly decrying the health disaster of jetlag, so what is it about changing the clocks that really gets people worked up?
