Description

ADD_MONTHS adds an integer months to a given date (DATE, DATETIME or TIMESTAMP), returning the resulting date.

months can be positive or negative.

The resulting day component will remain the same as that specified in date, unless the resulting month has fewer days than the day component of the given date, in which case the day will be the last day of the resulting month.
