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 enormous pumpkins for the feast by magic.
[edit] Halloween feast
The Halloween Feast at Hogwarts School of Witchcraft and Wizardry occurs on the 31st of 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 a highly anticipated feast which most Hogwarts students look forward to every year.
