How does Excel allow for leap years?

[Guest]

I am trying to calculate the number of years in a person's age by reference
to date of birth and today's date.
When I put DoB as 12/5/2003 against today's date of 11/05/2006, it comes
back as 3 whole years, when in fact it is 2 and 364 days. Excel seems to be
ignoring the leap year in 2004. If I use 13/05/2003 as DoB, it comes back
correctly as just 2 years.
How can I correct fro this via a simpel formula?

Many thanks in advance for all help received?

Thanks Peo, this basically helps me to solve it (as I only want the number of
complete years, I just need the first part of the formula).
By the way, I am not familiar with DATEDIF and it does not appear to be on
my list of available formuale in my version of Excle (Office Xp) (yet it
still works).

Alos, whilst I know what TODAY() is and I assume that, in your example, the
date for comaprison is in cell A1, what would be in cell A2?

Many thanks again.
