Hallowe'en

Halloween is a holiday celebrated by both Muggles and the wizarding world on 31 October. 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. On this day in 1981, the First Wizarding War ended with the disappearance of Lord Voldemort, after he murdered James and Lily Potter.

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.
