Select the range say A1:A10 and use the CF formula

=AND(A1TODAY(),A1-TODAY()<=30)

Hi, i have a date in a cell (17.06.2010). I need conditional formatting to
change the cell color with 30 days before that date to expire.

Something like this. if today is 18.05.2010 and i have 17.06.2010, than the
color of that cell to change.

Can this be done?
Thanks!
