Forum:Harry Potter Timeline

On Harry Potter Wiki it classifies the books by the year they are supposed to take place in. The first book which was released in 1997 is said to take place in 1991, but how was this decided?? Can someone please explain why the books take place from 1991 to 1998 and how this came to be? 67.190.217.36 08:31, 11 July 2009 (UTC)LarryPotter
