If you’ve ever found yourself needing to calculate the number of months between two dates in Excel, you’re not alone! 📅 Whether you’re working on a project timeline, tracking employee tenures, or analyzing data, having the ability to calculate the months between two dates can save you tons of time. In this guide, we’ll walk you through some effective methods to achieve this, share handy tips, and highlight some common mistakes to avoid.
Why Count Months in Excel?
Understanding the number of months between two dates can be crucial for various reasons, including:
- Project Management: Keeping track of project durations.
- Finance: Calculating interest or loan durations.
- HR: Managing employee benefits or service periods.
- Personal Planning: Tracking events, deadlines, or anniversaries.
Different Methods to Calculate Months in Excel
Excel provides various methods to count the number of months between two dates. Let’s dive into a few easy methods that you can implement right away.
Method 1: Using the DATEDIF Function
One of the easiest ways to calculate the number of months between two dates in Excel is by using the DATEDIF function. Here's a step-by-step breakdown:
- Choose Your Cells: Let’s assume you have the start date in cell A1 and the end date in cell B1.
- Enter the Function: In another cell (say, C1), type the following formula:
This will give you the total number of complete months between the two dates.=DATEDIF(A1, B1, "m")
Example:
If A1 is 01/01/2020 and B1 is 01/06/2020, the formula will return 5
.
Method 2: Using YEAR and MONTH Functions
If you prefer not to use the DATEDIF function, you can also calculate the number of months using the YEAR and MONTH functions. Here's how:
- Enter the Formula: In cell C1, input the following formula:
This will calculate the total number of months by first calculating the years and converting them into months, then adding the months directly.=(YEAR(B1)-YEAR(A1))*12 + MONTH(B1)-MONTH(A1)
Example:
Using the same dates as before, the result will also be 5
.
Method 3: Using NetworkDays Function (For Working Days Only)
If you’re interested in counting working days within a specific range, the NETWORKDAYS function can come in handy, although it doesn’t directly calculate months. However, you can derive insights about months worked in business scenarios.
- Enter the Formula: In cell C1, use:
Note that this function counts the number of working days between the two dates, which you can then analyze further.=NETWORKDAYS(A1, B1)
Important Notes on Using These Methods

Common Mistakes to Avoid
- Date Formats: Always ensure your dates are in a recognizable format by Excel (e.g., mm/dd/yyyy or dd/mm/yyyy).
- Understanding DATEDIF: Remember, DATEDIF is not officially documented in Excel, but it works in the background. Sometimes users may forget the “m” argument, leading to unexpected results.
- Date Order: Ensure the start date is earlier than the end date. Otherwise, the result may not make sense (it could return a negative value).
- Leap Years: If you are counting from February to March, consider how leap years may affect your total month count. For instance, February 29 in a leap year should be handled accurately.
Scenarios Where This is Useful
Scenario 1: Tracking Employment Tenure
Imagine you are an HR manager calculating how long a team member has been with the company. By entering their start date and today's date, you can quickly find out how many months they have been employed.
Scenario 2: Project Timelines
When managing a project, knowing how many months it has taken can help you assess timelines and make adjustments accordingly. Input your project start and end dates to get accurate figures on project duration.
