Ensuring accuracy in form submissions for the month of February

Question

Ensuring accuracy in form submissions for the month of February

I have a .net custom validator set up to validate an input date in a form. The validation should check the number of days in February, allowing 28/02/2015 but not 29/02/2015.

The C# server validation is functioning correctly with the following code snippet:

try
{
    DateTime dt = DateTime.Parse("29/02/2015");
}
catch
{
    args.IsValid = false;
}

This will return false when validated;

However, I am struggling to replicate the same behavior for client-side validation using JavaScript. Is there a straightforward way to achieve this in JavaScript?

Here's an updated version of my answer with a function that calculates the number of days in a given month and year:

function calculateDaysInMonth(month, year) {
   return new Date(year, month, 0).getDate();
}

//July
calculateDaysInMonth(7, 2009); //31
//February
calculateDaysInMonth(2, 2009); //28
calculateDaysInMonth(2, 2008); //29
