How to Calculate Date Difference in Excel: A Step-by-Step Guide

Calculating the date difference in Excel may seem tricky, but it’s a breeze once you get the hang of it. By using simple formulas, Excel can help you calculate the number of days, months, or even years between two dates. All it takes are a few clicks and a little bit of typing.

How to Calculate Date Difference in Excel

In this guide, we’ll walk you through the steps to calculate date differences in Excel using various methods. By the end of these steps, you’ll be able to find the exact duration between any two dates with ease.

Step 1: Enter Your Dates

First things first, you’ll need to input the dates you want to compare.

Enter your start date in one cell (e.g., A1) and your end date in another cell (e.g., B1). Make sure both dates are in a compatible date format.

Step 2: Use the DATEDIF Function

Next, you’ll use the DATEDIF function to calculate the difference.

In a new cell, type =DATEDIF(A1, B1, "d") to calculate the difference in days. "d" stands for days.

Step 3: Calculate the Difference in Months

To find out how many months are between the dates, modify the DATEDIF function.

Replace "d" with "m" in the formula: =DATEDIF(A1, B1, "m"). This will give you the number of full months.

Step 4: Calculate the Difference in Years

If you need the difference in years, change the interval in the DATEDIF function.

Replace "d" with "y": =DATEDIF(A1, B1, "y"). This will show you the difference in complete years.

Step 5: Use NETWORKDAYS for Business Days

For working days only, use the NETWORKDAYS function.

Type =NETWORKDAYS(A1, B1) to exclude weekends and only count business days.

Once you’ve completed these steps, Excel will automatically calculate the difference based on your chosen interval. Whether it’s days, months, or years, the result appears instantly.

Tips for Calculating Date Difference in Excel

• Always double-check your date formats to ensure they are consistent.
• Use cell references to make your formulas flexible and easy to update.
• Try the NETWORKDAYS function if you need to calculate working days.
• Don’t forget to add holidays in a separate range if you’re using NETWORKDAYS to make your result more accurate.
• Use conditional formatting to highlight date differences that meet specific criteria.
