Calculating the months between two dates in Excel is a common task that many users encounter, whether it's for business reports, project timelines, or personal planning. While Excel offers built-in functions to handle date calculations, understanding these methods will greatly enhance your efficiency and accuracy. Let’s dive into the seven simple ways you can calculate the number of months between two dates in Excel! ⏳
Method 1: Using the DATEDIF Function
One of the simplest methods to calculate the months between two dates is by utilizing the DATEDIF
function. This function is specifically designed for calculating differences between dates.
Step-by-Step Guide:
- Click on a cell where you want to display the result.
- Enter the formula:
Replace=DATEDIF(Start_Date, End_Date, "m")
Start_Date
andEnd_Date
with the actual cell references or dates.
Example:
=DATEDIF(A1, B1, "m")
In this example, A1 could contain the start date and B1 the end date. This will give you the number of complete months between the two dates.
<p class="pro-note">📝Pro Tip: Ensure that the start date is earlier than the end date, or you might get an error!</p>
Method 2: Using YEAR and MONTH Functions
If you want to calculate the difference in months while taking years into account, you can use a combination of the YEAR
and MONTH
functions.
Step-by-Step Guide:
- Use the formula:
=(YEAR(End_Date) - YEAR(Start_Date)) * 12 + MONTH(End_Date) - MONTH(Start_Date)
Example:
=(YEAR(B1) - YEAR(A1)) * 12 + MONTH(B1) - MONTH(A1)
This method gives you the total months between the two dates, including any partial months based on the day of the month.
<p class="pro-note">📅Pro Tip: This method works best when your start and end dates span multiple years!</p>
Method 3: NETWORKDAYS Function for Workdays
In scenarios where you only want to count business months (ignoring weekends), the NETWORKDAYS
function can be useful. While it won't directly calculate months, you can tweak it.
Step-by-Step Guide:
- Use the formula:
(22 is an approximation of the number of business days in a month.)=NETWORKDAYS(Start_Date, End_Date) / 22
Example:
=NETWORKDAYS(A1, B1) / 22
This will give you a rough estimate of how many business months are between the two dates.
<p class="pro-note">⚖️Pro Tip: This method does not consider months in terms of their actual lengths. Adjust the divisor according to your business days.</p>
Method 4: TEXT Function for Displaying Difference
If you want a quick text-based result (e.g., "X months"), use the TEXT
function.
Step-by-Step Guide:
- Combine it with the previous
DATEDIF
formula:=TEXT(DATEDIF(Start_Date, End_Date, "m"), "0") & " months"
Example:
=TEXT(DATEDIF(A1, B1, "m"), "0") & " months"
This will convert the numeric result into a string, making it more readable.

Method 5: Using EDATE to Generate a Series of Dates
If you're interested in generating a series of dates by adding months to a start date, the EDATE
function is perfect.
Step-by-Step Guide:
- Enter the formula:
=EDATE(Start_Date, Months_to_Add)
Example:
=EDATE(A1, 3)
This will give you the date that is three months after the start date in cell A1.
<p class="pro-note">📆Pro Tip: This is useful for creating a timeline or schedule based on starting points!</p>
Method 6: Combining IF and DATEDIF for Conditional Calculations
Sometimes, you may want to impose conditions on your calculations. The IF
function combined with DATEDIF
can be useful here.
Step-by-Step Guide:
- Use the formula:
=IF(Start_Date > End_Date, "Invalid Dates", DATEDIF(Start_Date, End_Date, "m"))
Example:
=IF(A1 > B1, "Invalid Dates", DATEDIF(A1, B1, "m"))
This formula checks if the start date is later than the end date, preventing errors.
<p class="pro-note">🔍Pro Tip: Always validate your date inputs to avoid mistakes!</p>
Method 7: Using a PivotTable for Dynamic Calculations
For more complex data sets, a PivotTable can help summarize the months between dates dynamically.
Step-by-Step Guide:
- Select your date data.
- Go to Insert -> PivotTable.
- Drag the date fields into the Rows and Values areas to analyze the time between dates.
This approach allows you to interactively analyze large datasets and see trends over time.
<p class="pro-note">📊Pro Tip: PivotTables are powerful tools that can uncover insights beyond simple date calculations!</p>
