Halloween
From Harry Potter Wiki
Halloween is a holiday celebrated by both Muggles and the wizarding world on October 31. At Hogwarts, there is a feast every year on Halloween and the first Hogsmeade weekend of the year usually occurs around the same day. Rubeus Hagrid grows massive pumpkins for the feast by magic.
[edit] Halloween feast
The Halloween Feast at Hogwarts School of Witchcraft and Wizardry occurs on the 31st October every year. Usually the Halloween Feast is festooned with sweets-filled pumpkins, bats, orange streamers, water snakes and all sorts of Halloween-related decorations. There is usually some entertainment at the end, this may be by the Hogwarts Ghosts who pop out of the walls and do formation gliding. It's an highly anticipated feast which most Hogwarts students look forward to every year.
