- (Year Unknown): Cedric Diggory's check-out of Quidditch Through the Ages from the Hogwarts Library ends.
- 1997: Albus Dumbledore's memorial service takes place at Hogwarts School of Witchcraft and Wizardry. During the ceremony, Harry Potter breaks his relationship with Ginevra Weasley. Minister for Magic Rufus Scrimgeour makes one final attempt to persuade Potter to support him; he receives the same response he did on Christmas.
