5 Excel Days Function Tips

Introduction to Excel Days Function

The Excel DAYS function is a useful tool for calculating the number of days between two dates. It is often used in various financial, administrative, and organizational tasks. In this article, we will explore five essential tips for using the Excel DAYS function effectively.

Understanding the DAYS Function Syntax

The DAYS function in Excel has the following syntax: DAYS(end_date, start_date). This function takes two arguments: the end date and the start date. The end date is the later date, and the start date is the earlier date. The function returns the number of days between these two dates.

Tip 1: Calculate Days Between Two Dates

To calculate the number of days between two dates, simply use the DAYS function with the end date and start date as arguments. For example, if you want to calculate the number of days between January 1, 2022, and January 15, 2022, you can use the following formula: =DAYS(“1/15/2022”, “1/1/2022”). This formula will return 14, which is the number of days between the two dates.

Tip 2: Calculate Days Between Today’s Date and a Specific Date

You can also use the DAYS function to calculate the number of days between today’s date and a specific date. To do this, use the TODAY() function as the start date or end date argument. For example, if you want to calculate the number of days between today’s date and January 1, 2022, you can use the following formula: =DAYS(TODAY(), “1/1/2022”). This formula will return the number of days between the current date and January 1, 2022.

Tip 3: Calculate Age in Days

The DAYS function can be used to calculate a person’s age in days. To do this, use the person’s birthdate as the start date and today’s date as the end date. For example, if you want to calculate the age in days of a person born on January 1, 1990, you can use the following formula: =DAYS(TODAY(), “1/1/1990”). This formula will return the person’s age in days.

Tip 4: Calculate Days Until a Specific Date

You can also use the DAYS function to calculate the number of days until a specific date. To do this, use the specific date as the end date and today’s date as the start date. For example, if you want to calculate the number of days until January 1, 2023, you can use the following formula: =DAYS(“1/1/2023”, TODAY()). This formula will return the number of days until January 1, 2023.

Tip 5: Using DAYS Function with Other Functions

The DAYS function can be used in combination with other Excel functions to perform more complex calculations. For example, you can use the DAYS function with the IF function to calculate the number of days between two dates only if a certain condition is met. You can also use the DAYS function with the ROUND function to round the result to the nearest whole number.

Function	Description
DAYS	Calculates the number of days between two dates
TODAY	Returns the current date
IF	Tests a condition and returns one value if true and another value if false
ROUND	Rounds a number to the nearest whole number or to a specified number of decimal places

📝 Note: The DAYS function is only available in Excel 2013 and later versions. In earlier versions of Excel, you can use the =END_DATE - START_DATE formula to calculate the number of days between two dates.

As we have seen, the Excel DAYS function is a powerful tool for calculating the number of days between two dates. By using the tips outlined in this article, you can use the DAYS function to perform a variety of tasks, from calculating ages and days until a specific date to using the function in combination with other Excel functions.
