Fanfic writers, take note.

The Harry Potter Lexicon, the go-to website for all true Harry Potter geeks, now features a Timeline of the Wizarding World. The timeline features hundreds of events in Wizarding history, ranging from obscure snippets--"1107 AD: Guthrie Lochrin of Scotland writes of the discomfort of riding broomsticks"--to more pertinent facts--Harry's birthday is July 31st. The timeline (actually, the entire site) is a conscientious fanfic writer's dream, and a testament to both Rowling's imagination and the amazing dedication of the fans that run the site.
