Conditional formatting to exclude weekend and Bank Holidays
 

Hi All

I am trying to use conditional formatting to show the difference between a
due date and a forecast date. For example, if the forecast date is up to 5
days from the due date the cell is green, if is between 6 to 10 days it
turns yellow and if it is 11 days or more it turns red. How can I
conditionally format(or any other way) so Saturday & Sunday, and if possible
Bank Holidays as well, aren't figured in as days?

Any help would be appreciated

Thanks

Paul
