Is it true that the first Harry Potter book was written in the same year that the Hogwarts battle ended in and what is the famous saying for J.K Rowling about this? I have heard about this but not clearly and want to read a more specific quote.
The Battle of Hogwarts took place on May 2, 1998. The first book, Harry Potter and the Philosopher's Stone was published some in year 1997.
I don't know about any famous saying on this.
