WEEKS
Returns the number of weeks between two dates.
This function is only available if the Analysis AddIn is installed.
Syntax:
WEEKS(startdate; enddate; mode)
- If mode is 0, WEEKS returns the number of whole weeks between startdate and enddate - that is INT(number_of_days_difference / 7).
- If mode is 1, WEEKS identifies the Monday_to_Sunday week that startdate and enddate each lie in, and returns the difference between those weeks.
- If startdate is after enddate the result will be negative.
Example:
WEEKS("2010-05-03"; "2010-05-17"; 0)
- returns 2. Both dates are Mondays, and there are 14 days between them.
WEEKS("2010-05-04"; "2010-05-27"; 0)
- returns 3; there are 23 days between the two dates.
WEEKS("2010-05-06"; "2010-05-17"; 1)
- returns 2; 6 May 2010 lies in week 3-9 May, and 17 May 2010 lies in week 17-23 May, two weeks later.
WEEKS("2010-05-09"; "2010-05-10"; 1)
- returns 1. 9 May 2010 is a Sunday and 10 May 2010 is the Monday of the following week.
Issues:
- This function is not available in Excel.
