Argument |
Description |
startdate |
Date from which to calculate days |
enddate |
Date to which to calculate days |
method |
[Optional] Method for calculating days; if FALSE or omitted, uses U.S. (NASD) method; if TRUE, uses European method. |
Specify the date argument as a number (as in 37806.5) a string (as in "7/4/2003 12:00"), or a DateTime object, as in DATE(2003,7,4).
The methods for calculating the number of days can vary. The U.S. or NASD method works as follows:
| • | If the starting date is the 31st of a month, it becomes equal to the 30th of the same month. |
| • | If the ending date is the 31st of a month and the starting date is earlier than the 30th of a month, the ending date becomes equal to the 1st of the next month. |
| • | If the ending date is the 31st of a month and the starting date is the 30th or 31st of a month, the ending date becomes equal to the 30th of the ending date month. |
The European method considers starting dates or ending dates that occur on the 31st of a month to be equal to the 30th of the same month.
Remarks
Use this function to help compute payments if your accounting system is based on a 360-day year (twelve 30-day months).
