I am trying to calculate someone's age on a date that is after their
birthday. I know how to do the calculation if I am going from a later date
to an earlier date but how do I go from an earlier date to a later date? for
example,
birthdate visit date
1 12/25/72 8/28/2007

Is there a calculation that can show how old the person was on the visit date?

Thank you!
