How to Calculate Number of Years Between Two Dates in Excel: A Guide

Calculating the number of years between two dates in Excel is a breeze once you know the right formulas. Whether you’re a student tracking project deadlines or a professional managing timelines, Excel makes it easy to work out these time differences. Here’s a quick guide to help you get started.

Step-by-Step Guide to Calculating the Number of Years Between Two Dates in Excel

In this section, we’ll break down the simple steps needed to calculate the number of years between two dates in Excel. These steps will help you perform the calculation accurately and efficiently.

Step 1: Open Excel and Enter Your Dates

Open a new or existing Excel sheet. Enter the starting date in one cell and the ending date in another cell.

For example, let’s say you enter "01/01/2020" in cell A1 and "12/31/2023" in cell B1. Make sure that Excel recognizes these as dates (they should align to the right by default).

Step 2: Select an Empty Cell for the Result

Choose a cell where you want the result of the calculation to appear.

Let’s pick cell C1 for this example. This is where you’ll see the number of years between the two dates displayed.

Step 3: Enter the Formula to Calculate the Year Difference

In the chosen cell, enter the formula =DATEDIF(start_date, end_date, "y").

So, in cell C1, you would enter =DATEDIF(A1, B1, "y"). This formula calculates the difference in years between the two dates.

Step 4: Press Enter to Get the Result

After typing in the formula, press Enter.

Excel will calculate the difference and display the number of years between the two dates in cell C1. In our example, it should show "3".

Step 5: Verify and Format the Result

Double-check your dates and the result to ensure accuracy. You can also format the result cell if needed.

If desired, you can format the cell to bold or change the font size for better visibility. This step ensures that your data is both accurate and easy to read.

Once you complete these actions, you’ll have the number of years calculated and visible in your chosen cell.

Tips for Calculating the Number of Years Between Two Dates in Excel

• Make sure your dates are in a format that Excel recognizes.
• Use cell references rather than typing dates directly into the formula to avoid errors.
• Double-check the cell formatting if the formula doesn’t seem to work.
• Be aware that the DATEDIF function is not available in all Excel versions, so ensure yours supports it.
• Remember to save your work regularly to prevent data loss.

Frequently Asked Questions

What if my dates are in different formats?

Excel should automatically recognize most date formats. If not, try reformatting them to a standard date format like MM/DD/YYYY.

Can I calculate the difference in months or days instead of years?

Yes, you can use the DATEDIF function with "m" for months and "d" for days.

What does the "y" in the formula stand for?

The "y" specifies that you want the difference calculated in years.

Is there an alternative formula to DATEDIF?

You can use a combination of other Excel functions like YEAR and YEARFRAC, but DATEDIF is straightforward for calculating years.

Why is the DATEDIF function not working in my Excel?

Ensure that you are using a version of Excel that supports DATEDIF. It may not work in some older or web versions.
