Sorry JMB this was my first time using on-line community, and I got my
replies mixed. Your formula was perfect. Thanks again.

Which date(s) tripped up the formula?

Thanks, but seemed to not be consistent with day of month later on in the
year eg. after 6, or 9 months.

Maybe:
=DATE(YEAR(A1),MONTH(A1)+3,MIN(DAY(A1),DAY(EOMONTH (A1,3))))

I want a table of dates for every 3 months after a starting date (could be
15th, 30th 31st etc). Difficulty when it is for example March 31 . The
formula :
=DATE(YEAR(starting date),MONTH(starting date)+3,DAY(starting date))
provides July 1. The correct date should be June 30.

The above formula works fine with days in the mid-month eg. 15th

I am wanting to avoid using the EOMONTH due to some starting dates are
mid-month. Formula should also deal with February!
Thanks
