Assuming you select the month by giving a number 1-12, the formual is:
(assuming year 2010)
=DATE(2010,A2,1)

Or, if the drop down list is actually a list of various dates, and you're
choosing a specific month:
=DATE(YEAR(A2),MONTH(A2),1)

Hi,

I want to be able to select the month from the drop down list and once the
month is selected, I want the first date cell to change itself to the
first
date of the month selected. For rest of the date cells I have just used
the
formula "First date cell + 1"

any help will be appreciated!!

Thanks a lot in advance.

P.S. - Sorry for posting this in two forums. I realized later that this
one is probably the right place to post it. Thanks.
