Harry Potter has spent July 31 many different ways: Stuck with the Dursleys in a hut on a rock in the middle of the sea; trying to convince an uninvited Dobby to leave Privet Drive; doing his homework in secret in the middle of the night while hiding under the covers; trying to ignore cruel comments from his horrible Aunt Marge. Historically, it hasn’t always been a great day for him. But it’s his birthday, and today, we celebrate another year of one of the greatest fictional characters of all time.

In honor of Harry’s birthday, we’ve made a quiz by which you can test your knowledge of the boy wizard — not the beloved and bestselling series of books about him, but the man himself. Find out how well you know Harry James Potter, ahead.
