Excel Formula to Calculate Days Until a Certain Date

Overview

To calculate the number of days from today until a specified future date in Excel, you can utilize the TODAY() function along with basic subtraction.

Formula

The formula to determine the number of days from the current date until a specified date (let's denote this cell as A1) is as follows:

=A1 - TODAY()

Explanation of the Formula:

1. TODAY(): This function returns the current date.
2. A1: This cell should contain the future date you are evaluating against today's date.
3. Subtraction: By subtracting TODAY() from the future date in cell A1, Excel calculates the difference in days.

Important Considerations:

• If the future date is before today's date, this formula will yield a negative number.
• If the future date is today, the result will be 0.
• Ensure that the cell A1 is formatted as a date type for the formula to work correctly.

Practical Illustration

Scenario:

Suppose you want to find out how many days are left until December 31, 2023. You would enter the date in cell A1.

1. In cell A1, input: 31/12/2023.
2. In another cell (e.g., B1), enter the formula:
   =A1 - TODAY()

Expected Output:

• If today's date is October 25, 2023, the output in cell B1 will be 67, indicating there are 67 days left until December 31, 2023.
