It really would not be difficult to move school later - school hours are already out of sync with 9-5 of 9-6 or the other hours parents work, if anything it’d be welcome.
Of course it would. School starts at roughly the same time as normal work hours. Most schools start a little before here to allow parents get to work after dropping off their kids.
You couldn't just change school hours in isolation without causing a lot of disruption.
School hours are 9-3:20 where I live, so they are nowhere near in line with working hours as you need time to get to work and not many jobs finish that early. Most schools run breakfast clubs and after school clubs as a result.
School began at 7:50 am for us. So that time worked well for parents and 9-5 sort of times. It gave enough room for 8-4 or 8-5 parents and long commute parents. Or parents who want to drop off and come back home first. If you make the school start time 9 am as well, if a parent helps their kid get ready and/or has to be around until the kid leaves for the bus and/or has to drop them off, they wouldn’t be able to unless their commute is short.
I don’t think school times can be pushed much. Maybe 30 min max without seriously disrupting parent’s schedules if that’s a concern.
