I am trying to set up a worksheet for work. I would like to have some
conditional formatting. In the date worked column will be dates going back
months if not years. I would like to set up color changes for dates that are
90, 120, 150 days older then the date at the time of opening the worksheet
=now(). Dates that are less then 90 days will have no color.

I am a fisherman and with this worksheet I could tell in a glance how long
it had been since I last worked an area.
