get days of a month

[webreake]

hi
im getting a problem when i try to get the days of a month here is my function:
function days(year, month) {
var thisMonth = new Date(year, month);
var nextMonth = new Date(year, month+1);
var Ndays = ((((nextMonth-thisMonth)/1000)/60)/60)/24;
return Ndays;
}

in september and november i get 31 days
I didnt try yet the Math.round but i want to know if
there is a better way to do this ?

Beware that the month variable to date functions (like new Date()) starts from 0, so january is 0, februrary is 1, and so on.

This is the very simple code to find the number of days in a month

function showDays(yr, mn){
var days:Date = new Date(yr, mn+1, 0);
trace(days.date);// It will trace total no. of days(28) in a month
}
showDays(2009, 1);// 1=February

this doesn't work...
here's another one I found that's JS but works for AS too.

function daysInMonth(iMonth, iYear)
{
return 32 - new Date(iYear, iMonth, 32).getDate();
}

trace(daysInMonth(1, 2009));
