How to calculate age in Excel in dd/mm/yyyy

Answer: Calculating age in Excel using the date format dd/mm/yyyy can be accomplished using various functions. Here’s a step-by-step guide to help you accurately determine age:

1. Using the DATEDIF Function

The DATEDIF function is specifically designed to calculate the difference between two dates. Here’s how you can use it:

  1. Enter the Birthdate:

    • Suppose the birthdate is in cell A1 in the format dd/mm/yyyy (e.g., 15/04/1990).

  2. Enter the Current Date:

    • You can use the TODAY() function to get the current date. In cell B1, enter =TODAY().

  3. Calculate the Age:

    • Use the following formula to calculate the age:
      =DATEDIF(A1, B1, "Y")
    • This formula calculates the number of complete years between the birthdate and the current date.

2. Using the YEARFRAC Function

The YEARFRAC function calculates the fraction of a year between two dates, which can then be converted to an integer to get the age.

  1. Enter the Birthdate:

    • Suppose the birthdate is in cell A1.

  2. Enter the Current Date:

    • Use the TODAY() function in cell B1.

  3. Calculate the Age:

    • Use the following formula:
      =INT(YEARFRAC(A1, B1))
    • This formula calculates the age in years by converting the fraction of the year to an integer.

3. Using the YEAR and MONTH Functions

Another method involves using the YEAR and MONTH functions to calculate the difference in years and months.

  1. Enter the Birthdate:

    • Suppose the birthdate is in cell A1.

  2. Enter the Current Date:

    • Use the TODAY() function in cell B1.

  3. Calculate the Age:

    • Use the following formula:
      =YEAR(TODAY()) - YEAR(A1) - (MONTH(TODAY()) < MONTH(A1)) - (AND(MONTH(TODAY()) = MONTH(A1), DAY(TODAY()) < DAY(A1)))
    • This formula calculates the age by subtracting the birth year from the current year and adjusting for whether the current month and day have passed the birth month and day.

Example:

Suppose you have the birthdate in cell A1 as 15/04/1990 (dd/mm/yyyy format).

  • In cell B1, enter =TODAY() to get the current date.
  • In cell C1, enter =DATEDIF(A1, B1, "Y") to calculate the age.

Alternatively, you can use:

  • =INT(YEARFRAC(A1, B1))
  • =YEAR(TODAY()) - YEAR(A1) - (MONTH(TODAY()) < MONTH(A1)) - (AND(MONTH(TODAY()) = MONTH(A1), DAY(TODAY()) < DAY(A1)))

These formulas will give you the age based on the birthdate in dd/mm/yyyy format.

By following these steps, you can accurately calculate age in Excel using the date format dd/mm/yyyy.
