Thursday is Back to Hogwarts Day. The Sept. 1 anniversary marks the day where characters in the Harry Potter universe return for their first day of classes at Hogwarts School of Witchcraft and Wizardry. While the main characters may have grown up and moved on, fans everywhere still rejoice and reflect on the days when Mr. Potter, Ron Weasley and Hermione Granger walked the halls of the legendary institution.
