Earlier quoted context omitted.
It's dark when we go out. It is dark when we come home. We get down to about 8 hours of daylight, I'm pretty sure. 8:15, I think? I could Google that. I'm at about the 47th.
8:25 is the shortest day in Seattle (a tad north of the 47th), which is further north than anywhere else that isn't in WA (except for that little piece of MN). That's being nit-picky, though, as the practical outcome is that anything less than nine hours means you'll go to work in the dark and come home in the dark.
The point of fussing with time zones (or the start-time for school/work, if you're in some weird place where people are capable of that) is so that you can go from "no morning or afternoon sun" to "morning or afternoon sun". You could tweak your 8.5 hours of daylight so that the sun rises at 6am and most people go to work/school in the sunlight and the sun sets at 2:30, or you could tweak it so that the sun rises at 10am and most people get some evening sun until 6:30.
It's not great but it's an option, instead of demanding the sun rises at 8am and sets at 4pm so that noon is noon and no one gets to enjoy it.
