Happy Birthday, Draco

Because Draco is a foil for Harry, and because his birthday doesn't seem to be associated specifically with any holiday, I think JKR picked it either because its profile matched the character well, or because she knew someone similar who she wanted to reference in her own secret way. And yeah, I still believe she used this book specifically. In all of profiles I've done, I haven't seen any that I consider to be a miss.
