How to Use the EOMONTH Function in Excel

Welcome to our tutorial on the EOMONTH function, available in both Excel and Google Sheets. This handy function determines the last day of the month for a specified number of months away from a base date. Whether calculating past or future end-of-month dates, EOMONTH simplifies date management in your spreadsheets. Let’s explore its usage more deeply.

Basic Syntax

The EOMONTH function is structured as follows:

EOMONTH(start_date, months)
  • start_date: The reference point or initial date. This can be either a direct date value entered through the DATE function or a cell reference that contains a date.
  • months: The number of months to move from the start_date. Positive values compute future dates, while negative values refer to past dates.
