# Calculate Number of Months Between Two Dates in Excel Have you ever needed to calculate the number of months between two dates in Excel? Whether you're working on a project, managing finances, or analyzing data, knowing how to calculate the month difference can be incredibly useful. In this tutorial, we'll explore different methods to calculate the number of months between two dates in Excel. Let's dive right in!

## Method 1: Using the DATEDIF Function

The easiest way to calculate the number of months between two dates in Excel is by using the `DATEDIF` function. This function calculates the difference between two dates in various units, including months.

The syntax for the `DATEDIF` function is as follows:

``````=DATEDIF(start_date, end_date, "M")
``````

Here's an example to illustrate how to use the `DATEDIF` function:

``````=DATEDIF(A1, B1, "M")
``````

In this example, `A1` represents the start date, and `B1` represents the end date. The third argument, `"M"`, tells Excel to calculate the difference in months.

Let's say we have the following dates:

Start Date End Date
2022-01-01 2022-12-31

To calculate the number of months between these two dates, we can use the `DATEDIF` function:

``````=DATEDIF(A2, B2, "M")
``````

The result will be `11`, indicating that there are 11 months between the start and end dates.

You can use the `DATEDIF` function in various scenarios. For example, you can calculate the number of months between a project's start and end dates, track the duration of a subscription, or analyze the length of time between two events.

## Method 2: Using the YEAR and MONTH Functions

Another way to calculate the number of months between two dates in Excel is by using the `YEAR` and `MONTH` functions. This method involves extracting the year and month components from the dates and then performing calculations based on those components.

Here's an example to demonstrate this method:

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

Let's use the same example as before:

Start Date End Date
2022-01-01 2022-12-31

To calculate the number of months between these two dates using the `YEAR` and `MONTH` functions, we can use the following formula:

``````=(YEAR(B2) - YEAR(A2)) * 12 + (MONTH(B2) - MONTH(A2))
``````

The result will be `11`, just like in the previous method.

This method provides more flexibility as you can perform additional calculations based on the extracted year and month components. For example, you can calculate the number of years and months between two dates by modifying the formula accordingly.

## Method 3: Using the EDATE Function

The third method to calculate the number of months between two dates in Excel is by using the `EDATE` function. This function adds or subtracts a specified number of months to a given date.

The syntax for the `EDATE` function is as follows:

``````=EDATE(start_date, months)
``````

Here's an example to illustrate how to use the `EDATE` function:

``````=EDATE(A1, 1)
``````

In this example, `A1` represents the start date, and `1` represents the number of months to add. The result will be the date that is one month after the start date.

To calculate the number of months between two dates using the `EDATE` function, you can subtract the start date from the end date and divide the result by the number of days in a month:

``````=(end_date - start_date) / 30
``````

Let's use the same example as before:

Start Date End Date
2022-01-01 2022-12-31

To calculate the number of months between these two dates using the `EDATE` function, we can use the following formula:

``````=(B2 - A2) / 30
``````

The result will be `11`, just like in the previous methods.

• When using the `DATEDIF` function, keep in mind that it may return unexpected results if the end date is earlier than the start date. To avoid this, you can use an `IF` statement to check if the end date is greater than or equal to the start date before calculating the difference.

• If you need to calculate the number of months between two dates excluding the partial months, you can use the `INT` function to round down the result.

• Remember to format the cells containing the formulas as numbers to ensure the correct display of the results.

• Excel stores dates as serial numbers, with January 1, 1900, being the starting point (serial number 1). This allows for easy calculations and manipulations of dates.
