5 Ways To Calculate Months Between Two Dates In Excel

Calculating the number of months between two dates in Excel can be surprisingly simple and incredibly useful, whether you're handling financial data, project timelines, or personal planning. Excel provides a range of functions to make this task easier, and in this article, we will explore five effective methods to calculate the months between two dates. 🗓️

Method 1: Using DATEDIF Function

One of the most straightforward methods to calculate months between two dates is to use the DATEDIF function. This hidden gem in Excel allows you to find the difference between dates in various units, including years, months, and days.

Steps to Use DATEDIF:

1. Select the Cell: Click on the cell where you want the result to appear.
2. Enter the Formula: Type =DATEDIF(start_date, end_date, "m"). Replace start_date and end_date with the actual date cells or dates.

Example: If you want to find the months between January 1, 2020 (A1) and July 1, 2020 (B1), you would enter:

=DATEDIF(A1, B1, "m")

This will return 6, as there are six full months between the two dates.

<p class="pro-note">📝 Pro Tip: Ensure your dates are formatted correctly, or you might encounter errors!</p>

Method 2: Using MONTH and YEAR Functions

If you're looking for a more manual method, you can leverage the MONTH and YEAR functions to perform your calculations.

Steps to Use MONTH and YEAR:

1. Select the Cell: Choose where the result will display.
2. Enter the Formula: Use the formula:

=(YEAR(end_date) - YEAR(start_date)) * 12 + MONTH(end_date) - MONTH(start_date)

This formula calculates the difference in years, converts that to months, and adds the difference in months.

Example: To find the months between dates in A1 (Jan 1, 2020) and B1 (July 1, 2020):

=(YEAR(B1) - YEAR(A1)) * 12 + MONTH(B1) - MONTH(A1)

This will also yield 6.

<p class="pro-note">📅 Pro Tip: This method counts complete months, but won’t factor in partial months!</p>

Method 3: Using EDATE Function

The EDATE function can also be a helpful tool in calculating month differences by counting how many months you would need to add to a date to reach the other date.

Steps to Use EDATE:

1. Select the Cell: Where you want the result.
2. Enter the Formula: To find the end date after adding months, use:

=DATEDIF(start_date, EDATE(start_date, months_to_add), "m")

Example: To check how many months you can add from Jan 1, 2020 (A1) to reach July 1, 2020 (B1):

=DATEDIF(A1, EDATE(A1, 6), "m")

This tells you how many complete months it takes from the start date to reach or exceed the end date.

<p class="pro-note">⏳ Pro Tip: EDATE is very useful for forecasting end dates based on start dates and intervals!</p>

Method 4: Calculating with NETWORKDAYS and Days

Another method involves calculating the total days between two dates using NETWORKDAYS, and then converting that total into months.

Steps to Use NETWORKDAYS:

1. Select the Cell: Click on where you wish the result.
2. Enter the Formula:

=NETWORKDAYS(start_date, end_date)/30

This will give you the number of months based on a 30-day approximation.

Example: For dates in A1 and B1:

=NETWORKDAYS(A1, B1)/30

The result will give you a rough estimate of months between the two dates.

<p class="pro-note">📈 Pro Tip: This method is an approximation and may not give exact months due to varying month lengths!</p>

Method 5: Using YEARFRAC

Lastly, the YEARFRAC function can also calculate the fraction of a year represented by the number of whole days between two dates.

Steps to Use YEARFRAC:

1. Select the Cell: Where the result will show.
2. Enter the Formula:

=YEARFRAC(start_date, end_date) * 12

Example: To find the months between the dates in A1 and B1:

=YEARFRAC(A1, B1) * 12

This provides you the number of months as a decimal, which can be useful for finer calculations.

<p class="pro-note">🌟 Pro Tip: YEARFRAC can be precise and allows for fractional months to be easily identified!</p>
