- Between 1991 and 1998: Millicent Bulstrode's check-out of Quidditch Through the Ages from the Hogwarts Library ends.
- 1998: Harry Potter, Ron Weasley and Hermione Granger — amongst others — stay at Shell Cottage and prepare to break into the Lestrange Vault in Gringotts Wizarding Bank.
- 2014: The opening match of the 427th Quidditch World Cup takes place. The crowd is still very hostile toward the Norwegians since the unfortunate events of the opening ceremony the day before, and the match is twice halted for security wizards to stop spectators jinxing Norwegian Chaser Lars Lundekvam. Ivoirian Chaser Elodie Dembélé scores seven goals. Norwegian Seeker Sigrid Kristoffersen captures the Snitch before her counterpart Sylvian Boigny. The 128-minute-long match ends with Norway defeating Ivory Coast 340 to 100.
