How do you use YEARFRAC in Excel?

The YEARFRAC function in Excel returns the fraction of the year represented by a given date. The date can be in any valid Excel date format. The function takes two arguments: the date, and the number of days in the year. The function returns a number between 0 and 1, representing the fraction of the year that has elapsed as of the given date. For example, if you enter the date "1/1/2018" into the function, it will return the value 0.5, because January 1, 2018 is halfway through the year. If you enter the date "12/31/2018" into the function, it will return the value 1.0, because December 31, 2018 is the last day of the year.

Where:

What is an example of how to use YEARFRAC in Excel?

When should you not use YEARFRAC in Excel?

There are occasions when you should not use YEARFRAC in Excel. One instance is when you are working with a table of data that includes dates in different years. In this case, Excel will calculate the fractional part of the year for the date in the current year, which will not be accurate for the other dates in the table. Another time you should not use YEARFRAC is when you are working with a large data set. Excel may not be able to calculate the fractional part of the year for all of the dates in the data set, which could result in inaccurate calculations.
