alt Hacker NewsI don't understand what you're trying to say.
The northernmost tip of the continental US gets about 8 hours of daylight during winter solstice. School is normally about 6.5 hours, so it's possible to give kids at least 45 minutes of daylight on either end of school any day of the year. Obviously not possible in Alaska, but possible in the other 49.
If you insist on your time zones being an hour wide, that makes it 15/75 and 75/15 on the edges. 15 minutes isn't a lot of time to walk to/from school, but that's only the week of winter solstice which is often during Christmas break anyways. Every week away from solstice adds about 15 minutes.
Okay, you do understand what I’m trying to say, so what am I supposed to respond? Tell me what your calculations for the school day year-round would best be in Washington State, and Maine.
