Harry Potter's class schedule isn't laid out in a single, neat timetable like you'd find in a school handbook—it's scattered throughout the books, pieced together from various scenes and offhand mentions. The most detailed glimpses come from 'Harry Potter and the Philosopher's Stone' and 'Harry Potter and the Order of the Phoenix,' where Harry's daily routines at Hogwarts get more attention. For example, in the first book, we learn first-years have classes like Potions with Snape, Transfiguration with McGonagall, and Herbology with Sprout, usually scheduled in blocks (morning or afternoon). The 'timetable' itself is mentioned when the Gryffindor first-years receive theirs during breakfast, but J.K. Rowling doesn't dump a full spreadsheet on us—it's more about the vibe of juggling magic subjects while dodging Filch.
Later books sprinkle in extra details, like the nightmare that is double Potions with the Slytherins or the rotating schedule for Divination. 'Order of the Phoenix' gives us a taste of Harry's O.W.L. year stress, with back-to-back classes and Umbridge's useless 'theory-only' lessons. If you're trying to reconstruct a full schedule, fan wikis like the Harry Potter Lexicon or Pottermore (now Wizarding World) have done the heavy lifting, compiling mentions from all seven books. Personally, I love how messy it feels—like real school, where you’re constantly referencing your planner but still end up in the wrong corridor half the time.
