SUMMARY

This article describes how to create a formula that returns the last or first day of the current month in Microsoft Excel.

MORE INFORMATION

You can use the EOMONTH function to return the last day of the current month. For example, the following formula

=EOMONTH(TODAY(),0)

returns the last day of the current month. Because the second argument (the MONTHS argument) is 0 (zero), the function assumes that the month that you want to use is the current month. If the second argument is 1, the function returns the last day of the following month.

To find the first day of the following month, use the following EOMONTH function:

=EOMONTH(TODAY(),0)+1



This function is part of the Analysis ToolPak add-in. If you do not click Tools, and then click Add-ins to install and enable the Analysis ToolPak add-in, the formula will return a #VALUE error. You will also receive a #NAME error if either of the function arguments is nonnumeric.
