How many dates are in each month?

Question

Is there an easy way to determine how many dates are in each
month?
as of right now I am looping through creating a new Date()
and when the month changes I know the last date of the month.
This is kind of slow, and building a switch statement would
be kind of exhaustive.
Any ideas?

This method is created from the same named method in
mx.controls.CalendarLayout:
private function getNumberOfDaysInMonth(year:int,
month:int):int{
var n:int;
if (month == 1) {
if (((year % 4 == 0) && (year % 100 != 0)) || (year
% 400 == 0))
n = 29;
else
n = 28;
else if (month == 3 || month == 5 || month == 8 || month ==
10)
n = 30;
else
n = 31;
return n;
