Hi, I'm creating a database of ages on people. What I need is to create
a formula that will tell me how old they are on the current day; i.e. if
a Person A's birthday is 2/27/80, then the Age Column will read "25"
today (2/26/06). But when I open the file tomorrow (2/27/06) it will
change to "26".

I.e. I don't want to manually have to update the Age Column. Is there
a formula to do this?

So far I've come up with Column A=Birthday, Column B=Today's date (with
the formula "TODAY()") and when I subtract A from B, it gives me a year,
where the age is the last 2 digits. How can I take that number and
convert it into the person's age?

Ex. 2/26/2006 - 8/18/1967 = 7/11/38. While the 7/11 is superfulous, 38
is the age. But how do I convert that number to state that?

=ROUND((B15-A15)/365.25,0)
just subtract the two cells and round it to the nearest whole number

Hi!

Try this:

A1 = birth date
B1 = =TODAY()

=DATEDIF(A1,B1,"y")

Fidelio,

There is an undocumented Excel function called "DATEDIF" which will help you
out here. Try:

=DATEDIF(A1,TODAY(),"y")
where A1 contains the persons birthdate.

For more info on this function, have a look at Chip Pearson's topic:
