|First, a posting tip:|
When you post a question in a help forum such as computing.net, please use a subject line that tells us something about your post.
If everyone used a generic subject line such as Excel Formula, we wouldn't be able to tell one question from another.
I have edited the subject line of this thread.
As far as your question...
With your date is A1, it's as simple as =A1-90
