Subtracting dates in Excel to get the number of years can be done using the DATEDIF function, which calculates the difference between two dates in various units, including years. By following a few simple steps, you can easily determine the number of full years between two dates. Let’s dive into a step-by-step guide to achieve this in Excel.
How to Subtract Dates in Excel to Get Years
Want to know how many years have passed between two dates? The following steps will show you how to use the DATEDIF function in Excel for this purpose.
Step 1: Open Your Excel Spreadsheet
Make sure you have your dates entered in two separate cells. For example, let’s say you have the start date in cell A1 and the end date in cell B1.
Step 2: Choose a Destination Cell
Select the cell where you want the result to appear. This is where the number of years will be displayed.
Step 3: Enter the DATEDIF Formula
Type the formula =DATEDIF(A1, B1, "Y") into your chosen destination cell. This formula calculates the difference in full years between the two dates.
Step 4: Press Enter
Hit the Enter key on your keyboard to execute the formula. The cell should now display the number of years between the two dates.
Step 5: Check Your Result
Ensure the result in the destination cell is what you expected. Double-check your input dates to confirm accuracy.
After completing these steps, you’ll see the number of full years between your specified dates in the destination cell.
Tips for Subtracting Dates in Excel to Get Years
- Ensure your date format is consistent across all cells.
- If dealing with leap years, be aware that this method calculates full years and ignores partial years.
- Use cell references in formulas to make your spreadsheet more dynamic.
- Double-check the order of your dates to avoid negative results.
- Familiarize yourself with other DATEDIF units like "M" for months and "D" for days for more flexibility.
Frequently Asked Questions
What happens if the end date is before the start date?
Excel will return a negative value if the end date precedes the start date.
Can I calculate the difference in months or days instead of years?
Yes, by changing the unit in the DATEDIF function to "M" for months or "D" for days.
What if my dates are not in the correct format?
Ensure that your dates are recognized by Excel as dates. Otherwise, the function may not work correctly.
Can I use this method for multiple date pairs?
Yes, you can apply the formula to multiple cells to calculate the difference for different date pairs simultaneously.
Are there any limitations to the DATEDIF function?
DATEDIF is an undocumented function in Excel, so it doesn’t appear in the Formula Wizard. However, it works reliably for many date calculations.
