Halloween feast

The Halloween Feast at Hogwarts occurs on the 31st October every year. Usually the Halloween Feast is festooned with candy filled pumpkins, bats, orange streamers, water snakes and all sorts of Halloween-related decorations. There is usaully some entertainment at the end, this may be by the Hogwarts Ghosts who pop out of the walls and do formation gliding.

In Harry's first year, the feast was interrupted by Professor Quirrell, who came in yelling that there was a troll on the loose and then fainted. The feast was cut short and all the students had to finish the feast in their common rooms.
