Their school day is divided into three blocks! Each block is two hours long. The first one is from nine in the morning to eleven. The second is from one to three. The third is from four to six. They only have classes Monday through Friday. Only ten of the fifteen blocks (spread out so there's two a day) are taken up overall.
Monday, the second of September, they have no classes. On Tuesday and Thursday they have Orientation (single House) in the first block. They have no other classes until the week of September the ninth, though, at which point their classes settle into what they'll be on non-holiday weeks.
