Q533 How can I calculate the number of days in the current month?

The following little gem was provided by Paul Bennett. At first look it looks too simple, but on closer investigation it is a pretty clever piece of code:

function days_in_month (year, month) {
     return 32 - new Date(year, month, 32).getDate();
}
