Example formula	Output

Notes

This function is not available for compatibility mode date types.

When using MONTH, QUARTER, or YEAR parts, if the resulting date is at (or near) the last day of the month, DATETIME_ADD returns the last day of the month. This can happen when the month in the resulting date has fewer days than the month in the starting date.

For example, if Date = August 31, 2020, DATETIME_ADD(Date, INTERVAL 1 MONTH) returns September 30, 2020.
