Perhaps a strange type of request however I have a list of 500 birthdates
and I need to calculate 30 days before the next birthday for each and
display that as a date. I'm using excel 2003 for windows and excel 2004 for
mac.

I can calculate the age as at the next birthday in years and of course the
current age. What I can't seem to figure out how to do is calculate the date
of the next birthday.

Any help would be most appreciated.

Thanks
