# How to Calculate the Difference Between Two Dates in Excel

We can use the DATEDIF() function to calculate the difference between two dates in Excel.

This function uses the following syntax:

• Start_Date: The start date
• End_Date: The end date
• Metric: The metric to calculate. Options include:
