For those who have grown up with the Harry Potter books and movies, today is the day you start to understand what it is to feel old. In the epilogue of the final book/movie of the series, Harry Potter and the Deathly Hallows, Harry and his wife Ginny are shown sending their son Albus off to Hogwarts, 19 years after the story ended (and 26 years after Harry and his friends began their education at Hogwarts). Ron and Hermione are also sending their daughter Rose to wizarding school. In the Potterverse, that date is September 1, 2017. JK Rowling sent a Tweet to remind fans of the date.
