conditional format based on date

cell C3 has a date of Mar 5, 2013. I want that cell to be green until after 90days. after 90 days I just want no fill.

so on until june 3, 2013 that cell should be green.

any ideas?

I have a similar setup on one of my spreadsheets.

Format cells that contain "Cell Value", "greater than", "=TODAY()-90". Set your format.

To test: 90 days ago from today was 12/5/12. This should appear with no fill. 89 days from today, 12/6/12, should appear in green.

I hope that helps!
