day(theDate[,value])
Alternatively, use Date.day.
day(theDate)
returns, as a Number, the day of the month from the theDate expression, which may simply be a date-type attribute value.
$MyNumber = day($MyDate);
day(theDate,value)
creates a new date based on the theDate expression, but in which the day of the month is value. theDate 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.
