Whether you need to calculate the number of days between two important events, or you simply want to keep track of how long it has been since a certain date, Excel can help. In this article, we will show you how to calculate the number of days between two dates in Excel.

Sample Calculation 1: Number of Days Between Two Dates

To calculate the number of days between two dates in Excel, you can use the DATEDIF function. For example, if you want to calculate the number of days between January 1, 2023 and December 31, 2023, you can use the following formula:

=DATEDIF(TODAY(),”12/31/2023″,”d”)

This formula will return the number of days until December 31, 2023.

Tips for Calculating Number of Days Between Two Dates in Excel

– Make sure that the dates you are using are in the correct format. Excel uses the MM/DD/YYYY format by default, so if you are using a different format, you may need to convert it first. – Double-check your formulas to make sure that you have entered them correctly. A small mistake can lead to a big difference in your calculations. – Use cell references instead of hard-coding dates in your formulas. This will make it easier to update your calculations if your dates change.
