I am using the following

=DATEDIF(C6,C5,"m")

If I enter the exact same dates the answer is obviously 0, but I want it to
be 1. I only want to add 1 if the dates are exactly the same.

In case it helps I am trying to figure out how far behind an account is, and
if the dates are the same a payment was not made and one more payment would
be due.

Any help would be great!
