Hi!
A general formula for adding (or subtracting) months that allows
copying across or down is:
=DATE(YEAR(A1),MONTH(A1)+AddMons,MIN(DAY($A$1),DAY(DATE(YEAR(A1),MONTH
(A1)+AddMons+1,0))))
Making the absolute reference to $A$1 ensures that the formula uses
the date in A1 if it exists AddMons ahead or the last date if it
doesn't. If you use a relative reference when copying down or across,
you can get some unusual series of dates.
An alternative that does the same by Peter Dorigo:
=MIN(DATE(YEAR(A1),MONTH(A1)+ AddMons +{1,0},DAY($A$1)*{0,1}))
