Have you ever needed to calculate the number of days between two dates in Excel? Whether you're tracking project timelines, calculating interest rates, or simply keeping track of important events, knowing how to calculate the day difference in Excel can be incredibly useful. In this tutorial, I'll show you how to do just that, step by step.
Getting Started
To calculate the number of days between two dates in Excel, we'll be using the DAYS
function. This function takes two arguments: the end date and the start date. It then returns the number of days between the two dates.
Here's the basic syntax of the DAYS
function:
=DAYS(end_date, start_date)
Now, let's dive into some examples to see how this function works in practice.
Example 1: Calculating the Number of Days Between Two Dates
Let's say we have two dates: July 15, 2023, and July 20, 2023. We want to calculate the number of days between these two dates.

In an empty cell, enter the following formula:
=DAYS("20230720", "20230715")
Note: Make sure to enclose the dates in quotation marks and use the YYYYMMDD format.

Press Enter to get the result.
The result should be
5
, indicating that there are 5 days between July 15, 2023, and July 20, 2023.
Example 2: Calculating the Number of Days Between Today and a Future Date
In this example, let's calculate the number of days between today's date and a future date.

In an empty cell, enter the following formula:
=DAYS("20230815", TODAY())
The
TODAY()
function returns today's date. 
Press Enter to get the result.
The result will be the number of days between today's date and August 15, 2023.
Example 3: Calculating the Number of Days Between Two Dates with Cell References
In some cases, you may have the start and end dates stored in separate cells. In this example, let's calculate the number of days between two dates using cell references.

In cell A1, enter the start date (e.g., "20230715").

In cell B1, enter the end date (e.g., "20230720").

In an empty cell, enter the following formula:
=DAYS(B1, A1)
This formula calculates the number of days between the dates in cells A1 and B1.

Press Enter to get the result.
The result should be the number of days between the start and end dates.
