5 Easy Ways To Calculate Months Between Two Dates In Excel

Calculating the number of months between two dates in Excel can be crucial for various tasks, whether you're analyzing project timelines, calculating age, or managing financial data. Thankfully, Excel offers multiple methods to achieve this calculation efficiently. Let's explore five easy ways to calculate the months between two dates, complete with practical examples and tips.

Method 1: Using the DATEDIF Function

The DATEDIF function is one of the simplest ways to calculate the number of months between two dates. This function is not widely known, but it can be extremely helpful.

Syntax

=DATEDIF(start_date, end_date, "M")

Example

Assume you want to find out how many months are between January 1, 2020, and April 1, 2021. You would use:

=DATEDIF("2020-01-01", "2021-04-01", "M")

Result: This will return 15, indicating there are 15 months between the two dates.

<p class="pro-note">💡Pro Tip: Ensure your date format is consistent to avoid errors in the calculations!</p>

Method 2: Using YEAR and MONTH Functions

Another method involves using the YEAR and MONTH functions. This technique is a bit more manual but gives you complete control.

Formula

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

Example

For dates January 1, 2020, and April 1, 2021:

=YEAR("2021-04-01") * 12 + MONTH("2021-04-01") - (YEAR("2020-01-01") * 12 + MONTH("2020-01-01"))

Result: Again, this will return 15 months.

<p class="pro-note">📝Pro Tip: This method is particularly useful when you want to see individual components, like years and months.</p>

Method 3: Using EDATE Function

The EDATE function can also help you calculate the months by adjusting your start date forward by a specific number of months.

Syntax

=DATEDIF(start_date, EDATE(start_date, number_of_months), "M")

Example

If you want to calculate the months from January 1, 2020, to April 1, 2021, you can set it up like this:

=DATEDIF("2020-01-01", EDATE("2020-01-01", 15), "M")

Result: You will also get 15 months, as expected.

<p class="pro-note">🚀Pro Tip: Use this method if you want to find a new date by adding months to an existing one!</p>

Method 4: Using TEXT Function with Concatenation

If you prefer a more visual approach, you can concatenate the dates and use the TEXT function to manipulate the output format.

Formula

=TEXT(end_date, "mmm") & " " & YEAR(end_date) - (YEAR(start_date)) & " years " & MONTH(end_date) - (MONTH(start_date)) & " months"

Example

Using the same dates:

=TEXT("2021-04-01", "mmm") & " " & YEAR("2021-04-01") - YEAR("2020-01-01") & " years " & MONTH("2021-04-01") - MONTH("2020-01-01") & " months"

Result: You will receive a textual output like "Apr 1 years 3 months".

<p class="pro-note">🔍Pro Tip: This method allows you to present your findings in a more human-readable way!</p>

Method 5: Using the MONTH Function with Intuition

If you’re comfortable using basic arithmetic, the MONTH function can also be your best friend in calculating the difference.

Formula

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

Example

Again, with January 1, 2020, and April 1, 2021:

=(MONTH("2021-04-01") - MONTH("2020-01-01")) + 12 * (YEAR("2021-04-01") - YEAR("2020-01-01"))

Result: This formula will yield 15 months.

<p class="pro-note">🎯Pro Tip: This method is straightforward and particularly effective when working with large datasets.</p>

Tips for Troubleshooting Common Mistakes

When working with date calculations in Excel, certain pitfalls are easy to fall into. Here are some common mistakes to avoid:

1. Incorrect Date Format: Excel can be sensitive to date formats. Ensure that both your start and end dates are formatted the same way.
2. Text Instead of Dates: Sometimes, dates may appear as text. Use the VALUE() function to convert text dates into recognizable date formats.
3. Negative Values: If the end date precedes the start date, Excel will return a negative number. Make sure your dates are in the correct order.
