Basic Formula for the DAYS360 Function:
Let us suppose we have the starting and ending dates and methods as shown in the screenshot below:
The steps to use basic DAYS60 function are described below:
Step 1: Enter the following formula in cell E2 and copy and paste the formula in cell E3 as well.
=DAYS360(A2,B2)
Explanation:
The formula =DAYS360(A2,B2) calculates the number of days between the start date (cell A2) and the end date (cell B2) using the US (NASD) method. The formula returns a result of 360, indicating that there are 360 days between the start and end dates based on the 360-day year convention.
The formula =DAYS360(A3,B3) calculates the number of days between the start date (cell A3) and the end date (cell B3) using the US (NASD) method. The formula returns a result of 21, indicating that there are 21 days between the two dates based on the 360-day year convention.
The DAYS360 function simplifies date calculations based on a 360-day year, but it’s important to understand the specific method being used and its impact on the results for accurate financial analysis and reporting.
Here is how DAYS360 basic formula use.

DAYS360 Function with Method argument for Finding Difference of Two Dates in Excel DAYS360:
In this illustration, we’ll utilize the optional argument to define the conversion method to 360 days per year.
For this, we have two options.
- US method
- European method
Try them both for the same start_date and end_date pair.
The steps to use basic DAYS60 function with method argument are described below:
Step 1: Enter the following formula in cell D2 for the European method.
=DAYS360(A2,B2,TRUE)
Step 2: Enter the following formula in cell D3 for the US method.
=DAYS360(A3,B3,FALSE)
Explanation:
The DAYS360 function in Excel is used to calculate the difference between two dates. In the given example, the start date is January 15, 2023, and the end date is May 31, 2023.
When the method is set to TRUE (European method), each month is considered to have 30 days. The result of the calculation is 135, indicating that there are 135 days between the two dates according to the European method.
When the method is set to FALSE (U.S. method), the actual number of days in each month is considered. The result of the calculation is 136, indicating that there are 136 days between the two dates according to the U.S. method.
The DAYS360 function is commonly used in financial calculations, but it may not always provide the exact number of days between two dates.

DAYS360 Function with the DATE Function:
The DAYS360 function in Excel can be combined with the DATE function to calculate the number of days between two dates. The DATE function allows you to create a valid date based on individual year, month, and day components.
Here’s an example of how you can use the DAYS360 function with the DATE function:
Suppose you have the year, month, and day components of the starting date in separate cells. Let’s say the year is in cell A2, the month is in cell B2, and the day is in cell C2. Similarly, you have the year, month, and day components of the ending date in cells D2, E2, and F2, respectively.
The steps to use basic DAYS60 function with the DATE function are described below:
Step 1: Enter the following formula in cell G2 and copy the formula by using auto handler in the rest cells.
=DAYS360(DATE(A2,B2,C2), DATE(D2,E2,F2))
In this example, the “Number of Days” column is calculated using the DAYS360 function combined with the DATE function, providing the accurate count of days between the specified start and end dates based on a 360-day year.
5. Things to remember while using DAYS360 Function:
When using the DAYS360 function in Excel, it is important to keep the following points in mind:
Date Format: Ensure that the dates provided as arguments are in a recognizable date format for Excel. If needed, format the cells containing the dates appropriately using the desired date format. Incorrect date formats may result in errors or inaccurate calculations.
360-Day Year Assumption: The DAYS360 function assumes a 360-day year, where each month is considered to have 30 days. Be aware that this is a simplified approach commonly used in financial calculations. If you require precise calculations based on actual days, consider using other date functions or formulas that account for the actual number of days in each month and leap years.
Method Argument: The DAYS360 function has an optional method argument that affects how the function handles certain scenarios, such as leap years and end-of-month dates. Choose the appropriate method based on your specific requirements. The default method is 0, but you can use 1 for adjusted end-of-month dates or 2 for adjusted leap years and end-of-month dates.
When using the DAYS360 function in Excel, it’s important to be aware of potential errors that may occur:
#NUM! error: This error occurs when the start_date and/or end_date arguments are numeric values that are not recognized as valid dates. Ensure that the arguments provided are in a recognized date format and not just numerical values.
#VALUE! error: This error can happen in two scenarios:
- a) If one or both of the arguments (start_date or end_date) are text values that cannot be interpreted as dates. Make sure the arguments contain valid date values or use the DATE function to construct dates from separate year, month, and day components.
- b) If the arguments provided are non-numeric. Ensure that the arguments are numeric values or use appropriate functions to convert them to numeric values if necessary.
By addressing these potential issues, you can minimize errors and ensure accurate calculations using the DAYS360 function in Excel.
