There are fans of Harry Potter who are incredibly devoted to the universe which author J. K. Rowling created on a train back from Manchester in 1990. Even though the books and the movies about 'The Boy Who Lived' are finished, it hasn't stopped people across the world from enjoying the small details which exist.
For those who know the wizarding world very well, they'd know that today is very special: the day when young wizards head to Hogwarts. However, this year is even more important, because 2017 is when Harry brings his son Albus Potter to Platform 9 ¾ for the first time.
Ms Rowling's tweet has spawned hundreds of comments from fans, thanking her for the reminder.
Fans have flocked to London's Kings Cross Station to mark the occasion as well.
The first book, Harry Potter and the Philosopher's Stone, recently celebrated its 20th birthday. After being knocked back twice, Ms Rowling finally got Bloomsbury to publish the novel on 26th June 1997. She received praise from The Guardian, The Sunday Times and The Mail on Sunday, and it went on to win the National Book Award and a gold medal in the Nestlé Smarties Book Prize.
Nearly two years after first being published, the novel had sold more than 300,000 copies and was still the UK's bestselling book until December 2001.
The novel is the fifth bestselling book of all time (not including any religious, ideological, philosophical or political ones), while the seven books as a whole is the bestselling series of all time with 500 million copies sold. Incredibly, the final book, Harry Potter and the Deathly Hallows, sold 11 million copies in the 24 hours after it was first released in 2007.
