How do I compute the age of someone from their birthdate?

Copy and paste the function Dave posted - or if you want to avoid code, put
a calculated field in a query:

Age: DateDiff("yyyy", [DOB], Date()) - IIF(Format([DOB], "mmdd") >
Format(Date(), "mmdd"), 1, 0)

Replace Date() by a literal date in # delimiters or by another field or form
reference if you want the age as of some selected date.
