Microsoft Excel age Calculation Methods
To calculate someone’s age using their date of birth, follow these simple steps:
Method 1: Calculate Age Using the DATEDIF Function
The DATEDIF function in Excel allows you to calculate the difference between two dates in years, months, or days. To calculate age using the DATEDIF function, follow these steps:
1. Enter the Date of Birth: In an Excel spreadsheet, enter the person’s date of birth in a cell. Make sure to use the correct date format (e.g., DD/MM/YYYY or MM/DD/YYYY) for consistency.
2. Enter the Current Date: Next, enter the current date in a separate cell. You can use the TODAY() function to automatically populate the current date. For example, if the current date is in cell A1, enter “=TODAY()” in cell A1.
3. Calculate the Age: In a new cell, enter the following formula: “=DATEDIF(DateOfBirthCell, CurrentDateCell, “Y”)”. Replace “DateOfBirthCell” with the cell reference containing the date of birth, and “CurrentDateCell” with the cell reference containing the current date. The “Y” in the formula specifies that the result should be in years.
Example: Suppose the date of birth is in cell B2, and the current date is in cell A1. The formula would be “=DATEDIF(B2, A1, “Y”)”. The cell will display the person’s age in years.

Method 2: Calculate Age Using the YEAR and TODAY Functions
Another method to calculate age is by subtracting the birth year from the current year. This approach is simple and doesn’t require the DATEDIF function. Here’s how to do it:
Enter the Birth Year: Enter the person’s birth year in a cell.
Calculate the Age: In another cell, subtract the birth year from the current year using the formula “=YEAR(TODAY()) – BirthYearCell”. Replace “BirthYearCell” with the cell reference containing the birth year.
Example: If the date of birth is in cell B2, the formula would be “=YEAR(TODAY()) – B2”. The cell will display the person’s age in years.

Method 3: Calculate Age Without a Cell Reference
If you don’t have the date of birth in a specific cell, you can directly input the birth year and calculate the age using the TODAY() function. Here’s how:
Enter the Birth Year: In a cell, enter the person’s birth year.
Calculate the Age: In another cell, subtract the birth year from the current year using the formula “=YEAR(TODAY()) – BirthYear”. Replace “BirthYear” with the actual birth year.
Example: If the birth year is 1990, the formula would be “=YEAR(TODAY()) – 1990”. The cell will display the person’s age in years.
Formatting the Age Cell: To ensure the age is displayed correctly, you may need to format the age cell. Right-click on the cell, select “Format Cells,” choose the “Number” tab, and select “General” or “Number” format. Click “OK” to apply the formatting.
Conclusion
Calculating age in Microsoft Excel is a simple process that can save you time and effort. Whether you choose to use the DATEDIF function or the YEAR function with TODAY, Excel provides versatile methods for age calculations.
