Associating each month with the respective final day of the month

Is there a way to link the month number with the corresponding last day of the month, including accounting for February's leap year where the last day is 28 unless it's 29?

Answer №1

If you need to find the final day of the month, you can achieve it using the following code:

var month = 1; // February
var date = new Date((new Date()).getYear(), month + 1, 0);
alert("The last day of the month is: " + date.getDate());

Below is how you can turn it into a function for ease of use:

function getLastDayOfMonth(month) {
   return (new Date((new Date()).getYear(), month + 1, 0)).getDate();
}
