California requires 180 days per year, and a lot of districts have no extra days built into the schedule. They did lower the number of hours in a "day" from 6 hours to 4. I think that is why so many districts have gone with remote learning days instead of a snow day, they don't the spare days. Just two weeks ago we had a big storm come through.....no snow, but a couple of schools didn't have electricity but they didn't close, they just switched to an early dismissal, 4 hour day. That has divided some parents who thought they should have canceled school, and others who say, it the kids could be there for 4 hours with no power, they could have stayed the extra 2 hours for a normal day.
