7 Simple Ways To Calculate Months Between Two Dates In Excel

Calculating the number of months between two dates in Excel can sometimes feel like a daunting task, especially if you're new to using spreadsheets. But fear not! With the right tools and techniques at your fingertips, you can easily tackle this with a few simple methods. Whether you’re managing project timelines, calculating subscription periods, or just indulging in curiosity, understanding how to calculate the difference in months can be incredibly useful. Let’s dive into seven effective methods to accomplish this! 📅

1. Using the DATEDIF Function

One of the most straightforward ways to calculate the number of months between two dates is using the DATEDIF function. This hidden gem in Excel allows you to calculate the difference between dates in days, months, or years.

Syntax:

=DATEDIF(start_date, end_date, "M")

Example:

If you have a start date in cell A1 (e.g., January 1, 2020) and an end date in cell B1 (e.g., April 1, 2020), your formula would look like this:

=DATEDIF(A1, B1, "M")

This will return 3, as there are three full months between the two dates.

2. Using YEARFRAC Function

Another method is to use the YEARFRAC function, which calculates the number of years between two dates and then multiplies that by 12 to convert it into months.

Syntax:

=YEARFRAC(start_date, end_date) * 12

Example:

Using the same dates in A1 and B1:

=YEARFRAC(A1, B1) * 12

Notes:

This method will return a decimal value. To get just the whole number of months, you can wrap it with the INT function:

=INT(YEARFRAC(A1, B1) * 12)

3. Simple Subtraction Method

Sometimes, simple subtraction works wonders! You can calculate the difference in days and then convert that into months by dividing by the average number of days in a month (approximately 30.44).

Formula:

=(B1 - A1) / 30.44

Example:

Using the dates in A1 and B1:

=(B1 - A1) / 30.44

Notes:

This might not give you an exact count of months if the days in the months vary significantly, but it's a quick and dirty method!

4. Combining MONTH and YEAR Functions

For more control, you can extract the months and years from the dates and calculate the difference manually.

Formula:

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

Example:

Using A1 and B1 again:

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

This formula gives you the total months, and it adjusts for any carryover if the end date is in a later year.

5. Using EDATE Function

The EDATE function can also help you find the difference by calculating a future or past date based on months.

Syntax:

=DATEDIF(A1, EDATE(A1, n), "M")

Where n is the number of months.

Example:

If you want to see how many months until a future date from A1, you can use:

=DATEDIF(A1, EDATE(A1, 12), "M")

This will calculate the difference in months between the start date and one year later.

6. Using NETWORKDAYS Function for Workdays

If you're calculating the number of business months between dates, you can adjust your approach to count only the working months.

Formula:

=NETWORKDAYS(A1, B1) / 20

Assuming an average of 20 working days per month.

Notes:

This method is useful for project management or tracking work hours but might require adjustments based on specific working conditions.

7. Using the EOMONTH Function

If you want to count the end of months, the EOMONTH function can help.

Syntax:

=DATEDIF(A1, EOMONTH(B1, 0), "M")

This will give you the number of months from the start date to the last day of the month of the end date.

Example:

=DATEDIF(A1, EOMONTH(B1, 0), "M")

This is particularly useful when evaluating financial periods or subscription cycles. 💰
