Rowling's "Harry Potter and the Philosopher's Stone" was published on June 26, 1997, then crossed the pond with the slightly altered "Sorcerer's Stone" title in its 1998 U.S. release.

Twitter honored the anniversary with a fancy hashtag -- #HarryPotter20 -- and fans from around the world are celebrating the milestone by sharing how much the series has meant to them.

It has meant the most to Rowling, who is not only insanely rich now, she has a world of new fans and friends. That validation has its own kind of magic. It was not inevitable that the story would play out this way, and Rowling knows that. She shared her gratitude in her own anniversary tweet:

Thank YOU!
