The Excel DATEDIF formula calculates the gap between two date ranges in the format of years, months, or days.

It was originally introduced in a very old Excel version and documented only in Excel 2000. But, it can still be used in the latest versions of Excel including Office 365.

In this tutorial, I’ll show you how to use Excel DATEDIF with the help of some examples. 

You’ll learn:

• Excel DATEDIF Syntax
• How to Use the Excel DATEDIF Function?
  • Example 1: Basic Uses of DATEDIF
  • Example 2: Calculate the Difference in Days Using DATEDIF
  • Example 3: Calculate the Difference in Months Using DATEDIF
  • Example 4: Calculate the Difference in Years Using DATEDIF

Excel DATEDIF Syntax

=SYNTAX(start_date,end_date,Unit)

Where start_date is the beginning date of the time period

end_date is the ending date of the time period and

Unit is the type of difference you are looking for ( days, months, or years) 

You can use the following time unit options inside the DATEDIF formula:

‘y’ – to find the difference in terms of complete years. 

‘m’ – to find the difference in terms of complete months. 

‘d’ – to find the difference in terms of complete days.

‘ym’ – to find the difference in months, ignoring months. 

‘md’ – to find the difference in days, ignoring months

‘yd’ – to find the difference in days, ignoring years. 

Note: Excel will not display or suggest the syntax for DATEDIF as it does for other normal functions.

How to Use the Excel DATEDIF Function?

The following examples will help you appreciate the formula’s usage better. I recommend you open a rough spreadsheet and follow along to gain a better understanding.

Example 1: Common Uses

In this example, column D contains the date March 1, 2019 and column E contains the date April 5, 2021. In column F, we can use the following variations of the DATEDIF function to calculate the difference in years, months and days respectively.

F5=DATEDIF(D5,E5,”y”) // returns 2

F6=DATEDIF(D6,E6,”m”) // returns 25

F7=DATEDIF(D7,E7,”d”) // returns 766

Example 2: Calculate the Difference in Days Using DATEDIF

In this example, we use the DATEDIF formula to calculate the difference in days between dates. Please note that you can use three different time units for days inside the DATEDIF function: (1) total days, (2) days ignoring years, and (3) days ignoring months and years. 

=DATEDIF(D11,E11,”d”) //  returns the difference in total days i.e 766 days

=DATEDIF(D12,E12,”yd”) // returns the difference in days ignoring years i.e 35 days

=DATEDIF(D13,E13,”md”) // returns the difference in days ignoring months and years i.e 4 days

Example 3: Calculate the Difference in Months Using DATEDIF

Use the DATEDIF formula to calculate the difference in months between dates. You can use two different time units for months inside the DATEDIF formula: (1) complete months and (2) in terms of months but ignoring years

=DATEDIF(D17,E17,”m”) // result: difference in complete months

=DATEDIF(D18,E18,”ym”) // result: difference in terms of months but ignoring years 

Example 4: Calculate the Difference in Years Using DATEDIF

Use the DATEDIF formula to calculate the difference in years between two dates. 

=DATEDIF(D21,E21,”y”) // difference in complete years

A small caveat: Since, DATEDIF rounds off the difference to the next lowest value, it is advisable to use YEARFRAC to find a more accurate difference in years.

Important Note:

The DATEDIF function returns the number of complete days, months, or years by rounding them off to the next smallest value. This means that it may give incorrect results when calculating the date difference in some cases. It is advisable to be careful while using DATEDIF and double-check the results before proceeding further.

The #NUM! error usually arises when the start_date is greater than the end_date.

The #VALUE! Error usually occurs when invalid arguments are used inside the formula.
