I have a date (1/31/08) and I need to add 25 years to it. I know the formula
to do this (=Date(YEAR(A4)+B4,MONTH(A4),DAY(A4)) where the answer is
12/10/2033. No problem. However, does this account for a leap year?

Leap years are already incorporated into the serial calendar used by Excel,
so you don't need to account for them. It's a done deal.

Yep.

But if your starting date were Feb 29, 2008, then since there isn't a Feb 29,
2033, your suggested formula would return Mar 1, 2033.

Is that what you'd want returned?

Easy enough to try - put 29 Feb 2008 in A4 and 25 in B4 and your
formula will return 1st March 2033, as there is no 29th Feb that year.
So, the formula does account for leap years, but when you start with
Leap Day you will get 1st March of the year 25 years hence. If you
start with 28th Feb, you will still get 28th Feb but 25 years on.

I'm not sure how you get your answer though - what did you have in B4?

Hope this helps.

If you have the Analysis ToolPak add-in installed, you could shorten your
formula:
Assuming B4 has 25
=EDATE(A4,B4*12)

I am curious as to what is in B4, as if you are just adding 25 years to the
date in A4 (given as 1/31/2008), and B4 is 25 years, my excel comes up with
1/31/2033, not 12/10/2033. The advantage of the EDATE function also is it
does take into account leap years.
Your formula, with date of 2/29/2008 in A4, the result would be 3/1/2033,
the EDATE formula results in 2/28/2033. So it wholly depends on what your
desired response would be.
