Age is just a Number, Not a Reminder...
As wise as an owl that I am here, dear, this not a Big difference so it makes no 'Difference' With... Asking her out.
You both are about the same age, going to the same college, I am assuming, so find out if there might be more in store and with the weekend, Ask her out to find out what it is all about, and if you have Something in common that will show you that there is great chemistry.
Good luck. xx
