Do you want to add 180 days rather than 6 months?
=DATE(YEAR(C4),MONTH(C4),DAY(C4)+180).
Excel is like a child; it does EXACTLY what you tell it and nothing more.
Your challenge is figuring out what to tell it to do.

I am having problems wtih getting the correct date. My start date is 03/12/06
in cell C4 and I want to calculate 6 calendar months from that date into
another cell. All I end up with is 09/12/06, when it should be done in
regular calendar months. The answer should be 09/21/06 but I don't know how
to get the formula to get that date. I tried using just the date function and
then tried edate function. Please help
