Tutorial: How to Calculate Your Current Age in Microsoft Excel

In this tutorial, we’ll walk through the steps to calculate your age using Microsoft Excel. This will involve setting up a simple structure and using the DATEDIF function to determine the difference between your date of birth and today’s date.

Step 1: Open Microsoft Excel

1. Press Windows + R to open the Run dialog.
2. Type Excel and press Enter. This will launch Microsoft Excel.

Step 2: Create the Structure

Set up your worksheet with the following labels in separate cells:

• A1: “Date of Birth”
• A2: “Today”
• A3: “Year”
• A4: “Month”
• A5: “Day”

Step 3: Check Your Date Format

Before entering dates, check your system’s date format (either dd/mm/yyyy or mm/dd/yyyy). This will help you input the correct format in the following steps.

Step 4: Enter Your Dates

1. In cell B1, enter your date of birth (e.g., 01/01/1990).
2. In cell B2, enter today’s date. You can use the formula =TODAY() to automatically insert the current date.

Step 5: Enter the DATEDIF Formulas

In the corresponding cells for Year, Month, and Day, enter the following formulas:

• In B3 (for Year):

  =DATEDIF(B1, B2, "Y")

• In B4 (for Month):

  =DATEDIF(B1, B2, "YM")

• In B5 (for Day):

  =DATEDIF(B1, B2, "MD")

Step 6: Test the Formula

To ensure everything is working correctly:

1. Change the date in cell B1 (Date of Birth) to a different date.
2. Observe the values in cells B3, B4, and B5 update automatically to reflect your current age in years, months, and days.

Conclusion

You’ve successfully calculated your age in Microsoft Excel! Feel free to modify the date of birth to test the formulas further.
