I was born in early February 1997. I'm trying to calculate between what dates I was in 5th grade. This is for the sake of recovering my runescape account, which I remember I played in 5th grade.

I tried looking up a calculator online for this, but surprisingly could not find one. I think it was in 5th grade from August 2007 to May 2008, but I don't want to be wrong on this.
