Hi,
If you have the dates in column A starting with row1, then you can use
following logic in conditional formatting:-
=IF(A1-NOW()<=30,"True","False")

Hello,

I have to track expiry dates in a datasheet. Actually, I'd like the expiry
date field to change color 30 days prior to the expiry date written in the
field. Let's say the expiry date is oct 24 2008, I want the field to change
color on sept 25 2008. The date format chosen is 24-oct-08, does it matter?

Thanks!
