The existing standard times already work? For Seattle on PST that puts sunrise at 7:54AM and sunset at 4:20PM in Seattle during winter solstice. Which gives almost an hour of sunlight on either side for a standard school day of 9-3:30.
For Bangor on it's 7:06AM and 4:03PM. It'd work better for an 8:30-3:00 school schedule. But for a 9-3:30 they'd unsurprisingly be better off on Atlantic Standard Time.
Now convince the parents that the kids should go to school at 9 and convince the companies that parents should start work at 10. I’m not really the one you need to bat around.
School start time is already 8:50AM in Seattle, no convincing needed.
They start earlier in Bangor, but the sun rises earlier in Bangor, so again everything already lines up quite well.
My kid’s elementary school in Seattle starts at 7:50 AM
Yeah, you can't have kids walking in daylight during the winter solstice unless all schools start at the same time. You can pick a time zone to match the school start time, or you can pick a school start time to match the time zone. But any school more that 30 minutes different has kids walking in the dark during the winter solstice.
