*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:

1 |
=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:

1 |
=DATEDIF(B3,C3,"ym") |

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

1 |
=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:

1 |
=YEARFRAC(B3,C3) |

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

1 |
=TRUNC(YEARFRAC(B3,C3)) |

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

1 |
=ROUND(YEARFRAC(B3,C3),0) |

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

1 |
=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.
