Happy 30-something birthday, Harry Potter!

Himmel Park Library celebrated his birthday and promoted the release of Harry Potter and the Cursed Child with games, appearances by Hogwarts professors, cake and dress up.

Much like this party, Antigone and Barnes & Noble will have weekend celebrations for Harry's birthday and the release of the script book, which happens to be the same day. Some things you can do on his actual birthday on July 31: attend any of these Tucson events, read the books again, watch the movies again, or play quidditch.

Check out some photos from the party and others we found (using magic):
