The Yule Ball is a tradition of the Triwizard Tournament. It is a formal dance held on Christmas night of a tournament year and is opened by the tournament champions and their partners in the Champions Waltz. At Hogwarts, where the Yule Ball was held in 1994, only students of fourth year and above were permitted to attend, though younger students could also go if an older student invited them to accompany them. The ball begins at 8:00 p.m. and ends at midnight.
