- ↑ In Britain, students leave primary school for high school when they are eleven. Summer break starts in the middle of July and Harry wouldn't have turned eleven until the end of July, so he was only ten when he left. Harry would have left anyway, since he recieved his letter for Hogwarts after and started there shortly after his eleventh birthday.
- ↑ Charlie Weasley was born in December 1972 according to both J.K Rowling's Official Site and the fact he was just over seven years older than Ron who was definitively born in March 1980. This means he started Hogwarts in September 1984. Nymphadora said she was in the same year as Charlie at Hogwarts in Harry Potter and the Order of the Phoenix. Therefore, they both would have left in July 1991.
