Calculating the number of months between two dates in Excel can seem like a daunting task, but with the right techniques and a bit of guidance, you can do it in just a few clicks! Whether you're managing a project timeline, analyzing financial data, or tracking milestones, knowing how to efficiently compute the interval between two dates can save you time and improve your accuracy. In this post, we'll break down several methods to get the number of months between two dates in Excel, along with helpful tips, common mistakes to avoid, and troubleshooting advice. Let’s dive right in! 🎉
Basic Method Using DATEDIF Function
One of the simplest ways to find the difference in months between two dates is to use the DATEDIF function. This function can calculate the difference between two dates in years, months, or days. Here's how to use it:
Step 1: Input Your Dates
Begin by entering your two dates in two separate cells. For instance:
- Cell A1:
01/01/2021
- Cell B1:
01/01/2022
Step 2: Use the DATEDIF Function
Now, in a new cell (let's say C1), enter the following formula:
=DATEDIF(A1, B1, "m")
Explanation:
- A1 and B1 are the cells containing your start and end dates.
- "m" tells Excel you want the difference in months.
Result
This formula will return 12
, indicating that there are twelve months between January 1, 2021, and January 1, 2022.

Advanced Method Using EDATE Function
If you prefer a method that offers flexibility, especially if you want to calculate end dates based on a given start date and number of months, the EDATE function is perfect for you.
Step 1: Input Your Start Date
In cell A1, enter your start date:
- Cell A1:
01/01/2021
Step 2: Use EDATE to Calculate Future Date
Now, in cell B1, enter the number of months you want to add. For example:
- Cell B1:
12
(for twelve months)
Step 3: Calculate the End Date
In another cell (C1), enter:
=EDATE(A1, B1)
Result
This will return the date that is twelve months from your start date, resulting in 01/01/2022
. Now, you can easily calculate the months between these two dates using the previous method if needed.
Calculating Partial Months
Sometimes, you might want to account for partial months when calculating the difference between two dates. Excel allows you to handle this using a combination of functions.
Step 1: Input Your Dates
- Cell A1:
01/15/2021
- Cell B1:
02/28/2021
Step 2: Calculate Full and Partial Months
In cell C1, use the following formula to account for both full and partial months:
=DATEDIF(A1, B1, "m") + (DAY(B1) >= DAY(A1))
Explanation
- This formula counts the full months and adds one more if the day of the end date is greater than or equal to the day of the start date.
Result
For our example, it will return 1
since there is one full month from January 15 to February 15, but you end up including the days until the end of February.

Common Mistakes to Avoid
When calculating the number of months between two dates, there are several common pitfalls to watch out for:
- Incorrect Date Format: Ensure your dates are formatted correctly (MM/DD/YYYY).
- Misusing DATEDIF Function: Remember to input the correct arguments; the start date should always come first.
- Ignoring Leap Years: Some years have an extra day in February, which can affect month calculations.
By being mindful of these mistakes, you can enhance your accuracy and efficiency with Excel's date functions.
Troubleshooting Tips
If you encounter any issues while using date calculations in Excel, consider the following troubleshooting steps:
- Check Your Date Formats: Go to "Format Cells" and ensure your dates are formatted correctly.
- Review Your Formulas: Ensure there are no typos or incorrect cell references in your formulas.
- Update Excel: Sometimes, older versions may have bugs or issues that can affect function performance.
