I have a database whith family records on, when our date of births are put in

1) All you should save in your table is the date of birth, not the
age. Any age saved in your table is going to be wrong within a year.

2) When you need that person's age, calculate it, in a query, form, or
report.

3) Here is an expression you can use to accurately calculate a persons
age. It takes into effect whether or not that month and day has
already passed.

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

Directly as the control source of an unbound control:
=DateDiff("yyyy",[DOB],Date())-IIf(Format([DOB],"mmdd")>Format(Date(),
"mmdd"),1,0)
