It’s September 1st, and many kids are getting ready to go back to school. It’s an emotional time, especially if your child is going somewhere new (my own baby starts NYU tomorrow!). But it’s not just the Muggles who are readying to hit the books; the young wizards of the Harry Potter universe will arrive today at Platform 9 3/4 at King’s Cross to embark on their journey to the Hogwarts School of Witchcraft and Wizardry for the start of the new school year.

This year is particularly notable as it marks the day that James Sirius Potter, the eldest child of Harry Potter and wife Ginny Weasley Potter, begins his first year at Hogwarts, according to author J.K. Rowling, who posted her best wishes to young James today via Twitter.
