It says in the last book that his parents died on halloween of 1981. Harry was a year old so that means he was born in 1980. The last book takes place when he was 17. 1980+17=1997. FAIL
I remembered the "19 years later" part after I posted this so nvm.
you're very stupid
Sorry that I forgot about one three page section at the very end of the last book. But you're right, it's not like I didn't realize my mistake and correct myself immediately after or anything. Because if I had done that, then you would just look like a dick.
