I don't think there is a native method to complete this. jared@aauser.com

I don't think javascript supplies a method for this either, but you can write your own. For example:

function isLeapYear
{
return (y%4==0 && y%100!=0) || y%400==0;
}
function daysInMonth(m,y)
{
if (m==1 || m==3 || m==5 || m==7 || m==8 || m==10 || m==12) {
return 31;
} else if (m==4 || m==6 || m==9 || m==11) {
return 30;
} else {
return isLeapYear ? 29 : 28;
}
}

// Get # of days in February for the current year
var md=daysInMonth(2,new Date().getYear());
