Calculating the number of months between two dates in Excel can be essential for various tasks, whether you’re tracking project timelines, calculating ages, or managing financial data. While Excel has built-in functions that can help with this, there are some simple ways to achieve this without getting bogged down in complex formulas. In this article, we’ll explore five straightforward methods to calculate the months between two dates, alongside helpful tips and potential pitfalls to watch out for.
Method 1: Using DATEDIF Function
The DATEDIF function is a hidden gem in Excel that calculates the difference between two dates. It’s perfect for finding the total number of months between two dates.
Steps to Use DATEDIF Function:
- Enter Dates: In cells A1 and B1, enter your start and end dates, respectively.
- Apply DATEDIF: In another cell (say C1), use the formula:
=DATEDIF(A1, B1, "M")
- Hit Enter: This will return the number of complete months between the two dates.
Important Notes:
<p class="pro-note">💡Pro Tip: Make sure your start date is earlier than your end date; otherwise, you'll get an error!</p>
Method 2: Using YEAR and MONTH Functions
You can also use the YEAR and MONTH functions to break down the dates and calculate the months manually.
Steps to Use YEAR and MONTH Functions:
- Enter Dates: Place your start date in A1 and your end date in B1.
- Calculate Months: In C1, use the formula:
=(YEAR(B1) - YEAR(A1)) * 12 + MONTH(B1) - MONTH(A1)
- Hit Enter: This formula calculates the total months by considering both years and months.

Method 3: EDATE Function
If you want to find a future date after adding a certain number of months, the EDATE function can come in handy. It can also indirectly help in determining the difference between two dates.
Steps to Use EDATE Function:
- Enter Start Date: Input your start date in A1.
- Calculate End Date: In B1, use the formula to find the date after adding months:
Here, C1 is the number of months you want to add.=EDATE(A1, C1)
- Compare Dates: To find out how many months are between, apply the DATEDIF function similarly to Method 1.
Important Notes:
<p class="pro-note">🗓️Pro Tip: EDATE is great for financial projections, but make sure you understand its context!</p>
Method 4: Using YEARFRAC Function
The YEARFRAC function calculates the difference between two dates in years, but you can easily convert that into months.
Steps to Use YEARFRAC Function:
- Input Your Dates: Place your start date in A1 and your end date in B1.
- Calculate the Difference: Use the following formula in C1:
=YEARFRAC(A1, B1) * 12
- Hit Enter: This will return the difference in months, including any partial months as decimal points.
Important Notes:
<p class="pro-note">📊Pro Tip: The decimal values can be useful for detailed analysis, but you might want to round them off for a cleaner report!</p>
Method 5: Manual Calculation
If you prefer a more hands-on approach, you can also manually calculate months by tracking the number of months from the start to the end date.
Steps for Manual Calculation:
- List the Months: Write down each month between the two dates.
- Count: Simply count the months to get your answer.

Common Mistakes to Avoid
- Input Order: Always ensure the start date is before the end date to avoid errors.
- Incomplete Dates: Make sure your date format is consistent (e.g., MM/DD/YYYY or DD/MM/YYYY).
- Ignoring Partial Months: If you need exact months, remember that some methods might not count partial months.
Troubleshooting Issues
If your calculations don’t seem right:
- Check Date Formats: Ensure dates are formatted correctly in Excel.
- Re-evaluate the Functions Used: Sometimes a small mistake in the formula can lead to incorrect results.
