2 October is the 275th day of the year (276th in leap years). There are 90 days remaining.
- 1991: The Gryffindor first years had an Astronomy class at midnight, on the top of the Astronomy Tower.
- 1997: Ron becomes increasingly irritable (partly due to his possession of Salazar Slytherin's Locket) and around this time leaves Harry and Hermione to search for Lord Voldemort's Horcruxes on their own.
- 1999: A Quidditch match between the Ballycastle Bats and Caerphilly Catapults is scheduled to this day on the Ellis Moor Stadium, but has to be relocated as Muggles are spotted camping nearby.
