Adding 3 months to the date

[grant]

I need to add 3 months to the date in a date field. I've tried lots of things, but I can't get it to do it.

This should work:

Date( Month( Date_Field ) + 3, Day( Date_Field ), Year( Date_Field ) )

There are some caveats, however. First, if the month you are in has more days than the month three months ahead, and you are on one of the last days, then you're going to end up in the next month. For instance, if Date_Field is March 31, 2001 (3/31/2001) this calculation results in 6/31/2001, which FileMaker will translate to 7/1/2001 since June has only thirty days. If you want to account for this, so that it ends up at 6/30/2001, the equation begins to get a bit more complicated, but it is possible.
