Calculating age between two dates in Excel might seem tricky, but it’s actually quite simple once you know the steps. In this guide, I’ll show you how to use Excel formulas to find the age difference between two dates. By the end, you’ll know how to calculate age accurately and efficiently in any spreadsheet.
Step-by-Step Tutorial: Calculating Age Between Two Dates in Excel
In the following steps, you’ll learn how to calculate the age between two given dates using Excel formulas. Let’s dive in!
Step 1: Open your Excel spreadsheet
The first step is to open your Excel spreadsheet where you want to calculate the age.
Make sure your spreadsheet has at least two columns with dates. One column should have the birthdate, and the other should have the end date (like today’s date or another specific date).
Step 2: Select the cell for the age calculation
Decide where you want the age result to appear and select that cell.
Choosing a cell in the same row as your dates will keep your data organized and easy to read.
Step 3: Use the DATEDIF function
Type the formula =DATEDIF(start_date, end_date, "Y") into the selected cell, replacing start_date and end_date with the cell references of your dates.
The DATEDIF function is specifically designed to calculate the difference between two dates. The "Y" indicates that you want the result in years.
Step 4: Press Enter
After typing the formula, press Enter to see the calculated age.
Excel will now display the age in the previously selected cell. If everything is set up correctly, you’ll see the result instantly.
Step 5: Verify the result
Double-check the dates and the formula to ensure the calculation is accurate.
If the result seems off, ensure that your dates are in the correct format and that you didn’t make any typos in the formula.
After completing these steps, you should see the correct age calculated between your specified dates.
Tips for Calculating Age Between Two Dates in Excel
- Use the correct date format: Ensure your dates are formatted as dates in Excel.
- Absolute cell references: Use
$signs to fix cell references if you plan to copy the formula across multiple rows. - Account for leap years: The DATEDIF function considers leap years, so no need to worry about them.
- Error handling: Add error handling using IFERROR to manage incorrect input.
- Custom formats: Use custom date formats to display results in years, months, and days if needed.
