What Is Last Day Of The Month In Excel?

Last day of the month in Excel, as the name suggests, is used to find the last date of the given data. To find the last date of the month, we will use the inbuilt function of Excel called the EOMONTH. This function will help us to return the last date of the month. The functionality of this function is not only restricted to knowing the last date of the current month. But, we can choose to know the last day of the previous month or next month. We can also choose to know the last day of the month at the custom-defined gap of months.

For example, suppose we need to achieve the month's end date from the selected dates in the Excel worksheet in the below example.

  • The result of the EOMONTH function needs to be formatted as a date in "MM_DD_YY" format.
  • If the format of the “Date” is incorrect, a #NUM error will occur. To calculate the last day of the month, one can use Excel's TEXT function.
