day(theDate, dayNum)

creates a new Date based on the aDate expression, but in which the day of the month is dayNumDate is not changed unless theDate is an attribute and the attribute is re-setting itself:

$MyDateA = day($MyDate,14); $MyDate is unaltered

$MyDate = day($MyDate,14); $MyDate is changed

Examples. If $MyDate is July 4, 2009 then

$MyNumber = day($MyDate); …is 4

If $MyDate is July 4,2009, then

$MyDate = day($MyDate,5);

will change $MyDate to July 5, 2009.

The single-argument merthod, used to read the day in the date is documented separately: see day(aDate).
