month(aDate[, monthsNum])
Alternatively, use Date.month.
month(aDate)
returns the month from the aDate date/time expression, which may simply be a date-type attribute value.
month(aDate,monthsNum)
creates a new date based on the aDate date/time expression, but in which the month is monthsNum. The source Date is not changed unless theDate is an attribute and the attribute is re-setting itself:
$MyDateA = month($MyDate,14);
$MyDate is unaltered
$MyDate = month($MyDate,14);
$MyDate is changed
Examples. If $MyDate is July 4,2009, then
$MyDate=month($MyDate,5);
will change $MyDate to May 4, 2009.
The single-argument method that reads the months value is documented separately: see month(aDate).
