# How To Calculate Number of Days Between Dates in Excel

Microsoft Excel offers powerful tools for calculating the number of days between dates, making it an essential skill for managing schedules, deadlines, and data analysis. Whether you are tracking project timelines or analyzing historical data, understanding how to compute the number of days between dates will streamline your workflow and enhance your productivity.

## How To Calculate the Number of Days Between Dates in Excel

Calculating the number of days between dates in Excel is an easy process. By following a few simple steps, you can quickly determine the difference between two dates.

• ### Step 1. Enter the Dates

First, open Excel and enter your two dates in separate cells. For example, type the start date in cell A1 and the end date in cell B1.

• ### Step 2. Use the DATEDIF Function

In an empty cell, use the DATEDIF function to calculate the difference between the two dates. The syntax for the DATEDIF function is: =DATEDIF(start_date, end_date, “d”) Replace start_date with the cell reference for the start date (A1) and end_date with the cell reference for the end date (B1). The “d” specifies that you want the result in days. Your formula should look like this: =DATEDIF(A1, B1, “d”)

• ### Step 3. Press Enter

After typing the formula, press “Enter.” Excel will display the number of days between the two dates in the cell where you entered the formula. Check that the result is correct by verifying the dates and ensuring the formula is accurate. If there are any errors, double-check the cell references and ensure the dates are entered correctly.
