To the degree kids are standing around outside, they're already in the dark in northern US states (to say nothing about Canada and areas of Europe) for part of the year even with standard time.

And, yes, dynamic school schedules don't work because they need to be synced at some level with work schedules. A one-time shift might work though.

I mostly don't have a dog in this hunt. I pretty much set my own schedule absent the odd morning appointment.

In the northern states, sure. But now you’re expanding it to southern states and places on the edge of the transition zones.

Also, 2 hour late starts for cold are a fairly common thing to happen due to cold in northern states. Now you’re talking about 3 hour late starts.

It's a continuum, not a discrete state. Even in the northern states, they're out in the dark for perhaps 4-6 weeks. Now that will get extended to, say, 10+ weeks.
