The school board I was in wouldn't close school down until it was below -40C (-40F), if blizzard conditions were obstructing the vision of school buses, or if there was too much snow falling on the ground that they couldn't clear it in time.
That would leave about three or four days of school missed, but surprisingly only because of temperatures below -40C and maybe the odd blizzard.

How often would that happen?
