Should I Ask Her Out on My Birthday?

Hi, i am 16m and i like this girl 17f in my college, But IDK if its the right time to ask her out. We are good friends, usually chat everyday, and its my birthday on 13th so i wanna ask her out on 13th, but i am not sure that would she be comfortable with it. Coz she could think of it as going out with a friend alone, and the worst part is that on 14th there is a exam. But i really wanna spend my 17th birthday with her.
