## How to Calculate Date Difference in Microsoft Excel

Calculating the difference between dates in Microsoft Excel is essential for tracking time-sensitive projects and deadlines. This guide will show you how to use Excel’s date functions to find precise intervals between dates, enhancing your data analysis capabilities.

• ### Step 1. Input the Start and End Dates

Begin by entering the start and end dates in two separate cells. For example, place the start date in cell A1 and the end date in cell B1. Ensure these cells are formatted as “Date.”

• ### Step 2. Use the DATEDIF Function

Select the cell where you want the result to appear. Enter the formula “=DATEDIF(A1, B1, “d”)” to calculate the number of days between the two dates. Replace “d” with “m” for months or “y” for years if needed.

• ### Step 3. Press ‘Enter’ to Display the Result

After typing the formula, press “Enter.” The cell will display the difference between the dates according to the unit specified in the formula.

• ### Step 4. Verify the Calculation

Check the calculated date difference to ensure it reflects what you intended. Adjust the date format or formula parameters if necessary.

• ### Step 5. Apply the Formula to Other Data

If you need to calculate date differences for multiple rows, you can drag the fill handle from the result cell to copy the formula to other cells in the column, adjusting the cell references as needed.
