Number of Years Between Dates in Excel & Google Sheets

This tutorial will demonstrate how to calculate the number of years between two dates in Excel & Google Sheets.

 

DATEDIF Function

To calculate the number of years between dates you can use the DATEDIF Function with unit of measurement “y” for years:

=DATEDIF(B3,C3,"y")

The DATEDIF Function returns the number of full years between two dates. It will not give you a fractional value.

Next you can use the “ym” input with the DATEDIF function to return the remaining number of months:

=DATEDIF(B3,C3,"ym")

and join them together to output the number of years and months between two dates:

=DATEDIF(B3,C3,"y")&"Years and"&DATEDIF(B3,C3,"ym")&" Months"

YEARFRAC Function

Instead if you want to determine the number of years, including fractional values you can use the YEARFRAC Function:

=YEARFRAC(B3,C3)

You can add in the TRUNC or INT Functions to calculate the number of full years (just like the DATEDIF Function):

=TRUNC(YEARFRAC(B3,C3))

Or you can use the ROUND Function to round to the nearest year:

=ROUND(YEARFRAC(B3,C3),0)

Last, you can use the ROUNDUP Function to count any partial year as a full year:

 

=ROUNDUP(YEARFRAC(B3,C3),0)

Number of Years Between Dates in Google Sheets

All of the above examples work exactly the same in Google Sheets as in Excel.
