With the last formula, if you format the cell to only show the whole number, it will round it up a couple days before the birth day and you won't have the good person's age. Here's the exact formula you should use to find a person's age:

=DATEDIF(birthdate,now(),"y")

You won't find anything better than that ;)

If you remove the remainder using your method it will round UP if a person is 21.5 years old it will say they are 22.

Make sure you use =Floor(your_function,1) to round down.

George, so you're saying that formatting the cell to only show the whole number will automatically round it at the same time?

I was under the impression that it simply drops the remainder, without doing any rounding.

So, 21.5 would be 21.

Is this an incorrect assumption?
