How can I add months?

[john.daly]

You could just add 91 days. It won't be quite correct but maybe good enough. The next_rev field is a calculation field where the calculation is:

last_rev + 91

result is a date.

I want a add 3 months from a date filed in a field calculation.

I have a date field (last_rev) and the claculation field is next_rev, in this last field i need calculate three months after.

Example

last_rev = March 3,2001

next_rev = June 3,2001

How can I do this.
