How to Find and Use the DATEDIF Function in Excel

The DATEDIF function in Excel is a powerful tool for calculating the difference between two dates in various units such as days, months, or years. Despite not being listed in Excel's function autocomplete, it still works if entered manually. Understanding how to use this function is essential for data analysis and reporting. In this guide, we will explore the syntax, examples, and usage of the DATEDIF function.

Syntax and Usage

The basic syntax for the DATEDIF function is as follows:

DATEDIF(start_date, end_date, unit)

start_date: The start date of the period. end_date: The end date of the period. unit: The type of interval you want to calculate.

Supported Units

Y: Years M: Months D: Days DYM: Days, excluding the months and years YDM: Days, excluding the years MDY: Months, excluding the years
