Comment Latitude matters (Score 4, Interesting) 232
First: I'm on the side of eliminating DST.
Second: Most discussions seem to ignore latitude. This article sort of touches on it, as Canada is mostly north of the US lower 48. Further south in US the swings in hours of daylight aren't as big as the north. In the north the days are so much longer in the summer, much shorter in the winter. ( a 7.5 hour difference in Seattle vs a 4.5 hr difference in San Diego). While both in the same time zone; the difference in daylight hours is much greater than the current time change.
You know what's the same in both cities? Solar noon. Set the clock to match solar noon, or PDT, and the localities will sort out what works best for them for operating hours, school start times, etc.
And in the WTF dept: Alaska observes DST. Juneau peaks around 18.5 hrs of daylight at the summer solstice. Do they really need more hours of daylight after work? And the days are so short in December, kids would go to school *and* come home in the dark. I guess you could shift the clock a bit so only one is in the dark?
