I think teachers that give students a lot of homework due or a test on Nov 1st are just being downright crabby. You can give the students a break from time to time. Send them off without homework for one day and don't schedule a test on that day. It is simple enough. Having said that, the parents need to make sure to get their kids in at a decent hour on Halloween night.

I went to Catholic school, so we always had off on November 1 (All Saints Day).
