I'm in Canada but I'm pretty sure colleges and universities in a lot of places schedule classes like this. I can have days with no classes just because that's how it so happens that the classes I've enrolled in are scheduled. A couple years ago I had no classes until like 2pm on a certain day etc
Unless you mean my high school start time, which.... Canada? ?\_(ツ)_/? lol also in my last semester of grade 12 I had a spare first period and we used a block schedule so I didn't start until 10:30, good times
