J.K. Rowling reminded Harry Potter fans that Sept. 1, 2015 was a very important day in the Potter universe: James Sirius Potter’s first day at Hogwarts.

The beloved author tweeted the news early Tuesday morning, asking someone to wish Potter good luck on his first day at school.

Potter fans, obviously, obliged and celebrated what other anniversaries the first day at Hogwarts marks.

Rowling was inundated with messages for Potter and joked about his arrival.

Seems like James’ first day will be a little less scary than Harry’s.
