You need to set up 2 conditions. First condition (default) has to be:

=(A1-TODAY())<365

and format Red. Then click Add to set up the second condition:

=(A1-TODAY())<300

and format Yellow.

The first condition has priority over the 2nd (and 3rd). This assumes
that A1 is the cell selected.

Hope this helps.

Dear All,

I am looking for some help formatting cells with date entries using excel
2003.
I have tried using 'formula is' and '=(A1-TODAY())<300', and have seen
variations on this theme in other threads, but don't seem to be able to get a
formula to work with the following;

Date entered into cell (not necessarily 'todays' date). Cell turns yellow
when 300 days have elapsed from the date entered, cell turns red when 365
days have elapsed from the date entered

(I have the cells formatted for date)

Grateful for any help. Thanks.
