weeks(startDate, endDate)
This returns the Number of (7-day weeks) weeks between two dates, startDate and endDate. If the dates are within seven days of each other, the result is zero.
If $DateA is 3 January 2016 and $DateB is 20 January 2016, then:
$MyNumber = weeks($DateA,$DateB);
sets $MyNumber to 2.
If endDate is before startDate the result is negative.
