YEARFRAC() vs DATEDIF() in Excel - Excel Tips and Tricks

Discover how to calculate age using DATEDIF function in Excel. And be able to tell the compare YEARFRAC() vs DATEDIF() functions.

Calculating age using Excel's DATEDIF function is a quick and easy way to determine the age of a person based on their birthdate. By subtracting the birthdate from the current date and specifying the "year" interval unit, the formula returns the person's age in years. It is important to use the correct format for the birthdate and to ensure that the column width is wide enough to display the result. Using Excel to calculate age is particularly useful when working with large datasets or when multiple calculations need to be performed quickly and accurately.

YEARFRAC is an Excel function that calculates the fraction of a year between two dates. By using this function, you can easily calculate a person's age in years, months, and even days. To calculate age, you simply need to subtract the person's birth date from the current date and divide the result by 365.25 (to account for leap years). This will give you the person's age in years with decimal places. You can then use the INT function to round down to the nearest whole number and obtain the person's age in years. Alternatively, you can use the DATEDIF function to calculate the number of complete years between two dates, but this function does not handle leap years as accurately as YEARFRAC.


YEARFRAC vs DATEDIF

YEARFRAC and DATEDIF are both Excel functions used to calculate the difference between two dates, but they differ in their approach and output.
DATEDIF returns the difference between two dates in the specified interval unit, such as days, months, or years. It has limitations, such as not being able to calculate fractions of a year and not working correctly in certain situations.

YEARFRAC, on the other hand, calculates the difference between two dates in terms of a fractional number of years. This function is more versatile than DATEDIF, as it can calculate the fraction of years between two dates, and it can also calculate the number of days or months between two dates.

In summary, DATEDIF is useful for calculating differences between dates in terms of specific interval units, while YEARFRAC is useful for calculating the fraction of years between two dates.
