Google Sheets is an incredibly powerful tool for organizing and analyzing data. One of its most helpful features is its ability to perform date-based calculations, especially when you need to work with month-end or month-offset dates. The functions EOMONTH and EDATE are two essential tools for performing these calculations, helping you quickly and efficiently manage dates across months.
Whether you’re calculating due dates, projecting timelines, or tracking financial data, these functions are crucial for ensuring that your date calculations are accurate and easy to manage. In this article, we’ll explore how to use EOMONTH and EDATE in Google Sheets, provide examples, and show you how they can improve your workflow when working with dates.
What Are EOMONTH and EDATE in Google Sheets?
Both EOMONTH and EDATE are date functions in Google Sheets that allow you to perform month-based calculations. Here’s what each one does:
- EOMONTH: The EOMONTH function returns the last day of the month, a specified number of months before or after a given date. This is helpful for calculating deadlines, payment schedules, or the last day of the month in financial planning.
- EDATE: The EDATE function returns a date that is a specified number of months before or after a given date. This function is particularly useful for finding future or past dates based on a certain number of months.
How to Use EOMONTH in Google Sheets
The EOMONTH function can be used to find the last day of the month, given any starting date. This is particularly useful for accounting, planning, and tracking periods that end on the last day of the month.
Syntax for EOMONTH
=EOMONTH(start_date, months)
- start_date: The initial date from which the calculation will begin.
- months: The number of months before or after the start date. Use a positive number to find a future date, or a negative number to find a past date.
Example: Using EOMONTH for a Due Date
Let’s say you have a payment due every 3 months, and you want to calculate the next payment due date based on today’s date. If today’s date is January 15, 2025, the formula would look like this:
=EOMONTH("2025-01-15", 3)
This formula will return April 30, 2025, which is the last day of the month, 3 months after the given date.
Sample Data for EOMONTH Calculation
| Start Date | Months Ahead | Calculated EOMONTH |
|---|---|---|
| 2025-01-15 | 3 | 2025-04-30 |
| 2025-05-01 | -2 | 2025-03-31 |
How to Use EDATE in Google Sheets
The EDATE function allows you to calculate a date that is a certain number of months before or after a given date. This is especially useful for calculating due dates, subscription renewals, or project timelines.
Syntax for EDATE
=EDATE(start_date, months)
- start_date: The starting date from which you want to calculate.
- months: The number of months to add or subtract from the start date. Use a positive number for a future date and a negative number for a past date.
Example: Using EDATE for a Subscription Renewal
Imagine you have a subscription service that renews every 6 months, and you want to find the renewal date based on today’s date. If today’s date is February 10, 2025, the formula would look like this:
=EDATE("2025-02-10", 6)
This formula will return August 10, 2025, which is the date 6 months after the given date.
Sample Data for EDATE Calculation
| Start Date | Months Ahead | Calculated EDATE |
|---|---|---|
| 2025-02-10 | 6 | 2025-08-10 |
| 2025-06-01 | -3 | 2025-03-01 |
Real-Life Example: Financial Planning with EOMONTH and EDATE
