What was Harry Potter's timetable in his first year?

Answer 1

It would be practically impossible to reproduce Harry's timetable. JKR very obviously never wrote one out when she began the story. She often contradicts herself, and the teachers would have no chance of keeping to her schedule without time-turners.

A few things seem certain, however. School starts at 9am. Every day he has two periods, followed by break, followed by two periods, followed by lunch, followed by three periods, which end at 4pm. On Friday he has the final period free, so he finishes at 3:15pm.

He studies seven subjects: charms, transfiguration, herbology, potions, astronomy, defence against the dark arts and history of magic. One of the astronomy lessons is a practical, studied after dark in the Astronomy Tower, but there is probably a theory lesson during the week as well. There are broomstick-flying lessons on Thursday afternoons, and this seems to be an "extra" subject.

There are usually about 30-35 students in each class. (There are supposed to be about 120-150 students in each year-level, but we are only ever told the names of 40 of Harry's class.) For some subjects, e.g., potions, which require extra supervision, the students are split up into groups of 20. That is how Harry ends up sharing some classes with Slytherins.
