DAYS360 function: Description, Usage, Syntax, Examples and Explanation

What is DAYS360 function in Excel?

DAYS360 function is one of Date and Time functions in Microsoft Excel that returns the number of days between two dates based on a 360-day year (twelve 30-day months), which is used in some accounting calculations. Use this function to help compute payments if your accounting system is based on twelve 30-day months.

Syntax of DAYS360 function

DAYS360(start_date,end_date,[method])

The DAYS360 function syntax has the following arguments:

  • Start_date, end_date: The two dates between which you want to know the number of days. If start_date occurs after end_date, the DAYS360 function returns a negative number. Dates should be entered by using the DATE function, or derived from the results of other formulas or functions. For example, use DATE(2008,5,23) to return the 23rd day of May, 2008. Problems can occur if dates are entered as text.
  • Method(Optional): A logical value that specifies whether to use the U.S. or European method in the calculation.
Method Defined
FALSE or omitted U.S. (NASD) method. If the starting date is the last day of a month, it becomes equal to the 30th day of the same month. If the ending date is the last day of a month and the starting date is earlier than the 30th day of a month, the ending date becomes equal to the 1st day of the next month; otherwise the ending date becomes equal to the 30th day of the same month.
TRUE European method. Starting dates and ending dates that occur on the 31st day of a month become equal to the 30th day of the same month.

Note: Excel stores dates as sequential serial numbers so that they can be used in calculations. By default, January 1, 1900 is serial number 1, and January 1, 2008 is serial number 39448 because it is 39,447 days after January 1, 1900.
