How to work out someone's age on excel

Hello! I am trying to work out a person's age on excel. The DATEDIF function is not displaying and when I try (X - X / 365) I am not getting any results. Please can you advise on a formula. Also is the format of date (28-DEC-95) is correct for the formula - this how the data was provided to me.

Thank you.

RE: How to work out someone's age on excel

Hi Niamh,

Thank you for the forum question and the nice feedback after the course and the nice Trustpilot review.

I am happy the course was useful.

To calculate age the Datedif function is very useful.

=Datedif(Start date, End date, "y")

"y" in the third argument if you want the result in years.

If you have the date of birth (28-DEC-95) in A2 and the =today() function in A1 the function should look like this:
=Datedif(A2,A1,"y")

You will need to check if Excel understand your date format (28-DEC-95). If the date is right aligned in the cell, you are fine and the Datedif function will work. If the date is left aligned, you cannot do it, before you have changed the date to a format Excel understands as a date format.

Kind regards
