Returns the serial number for the last day of the month that is the indicated number of months before or after start_date. Use EOMONTH to calculate maturity dates or due dates that fall on the last day of the month.

## Syntax

EOMONTH(start_date, months)

The EOMONTH function syntax has the following arguments:

• Start_date Required. A date that represents the starting date. Dates should be entered by using the DATE function, or as results of other formulas or functions.
• Months Required. The number of months before or after start_date. A positive value for months yields a future date; a negative value yields a past date.

## Remarks

• Microsoft Excel stores dates as sequential serial numbers so they can be used in calculations. By default, January 1, 1900 is serial number 1, and January 1, 2008 is serial number 39448 because it is 39,448 days after January 1, 1900.
• If start_date is not a valid date, EOMONTH returns the #NUM! error value.
• If start_date plus months yields an invalid date, EOMONTH returns the #NUM! error value.
