Adds or subtracts months to a Date/Time value, with optional adjustment to the day of the month.
Description
The EDate and EOMonth functions move a Date/Time forward or backward by a specified number of months.
After the month adjustment, EDate leaves the day portion unmodified unless the new value would be beyond the end of the month. For example, moving July 31 backward by one month yields June 30. Use EDate to calculate the maturity dates or due dates that fall on the same day of the month as the date of issue.
After the month adjustment, EOMonth changes the day potion to the last day of the resulting month. Use EOMonth to calculate the maturity dates or due dates that fall on the last day of the month. EOMonth can be used to move a Date/Time to the end of the month by adding zero months.
All functions return a Date value. No time component is included, even if one was present in the input Date/Time.
See working with dates and times for more information.
