Can anybody shed some light on getDay() in Javascript please. Here datepicker is textbox where it gets value from Jquery DatePicker Control

var CallbackDateNumber;
// check for the value in Date of callback control
if(("#datepicker")!="")
{
    CallbackDateNumber = new Date($("#datepicker").val()).getDay();
}
else
{
    CallbackDateNumber=new Date().getDay();
}

For January Date its gives 0,1...6- From Sunday to Saturday.

But the same order is not preserved in Month Febraury.

Any reason why this happening?

• You do realize you are calling two different methods, getDay and getDate, right? – Brian Driscoll Commented Jan 31, 2012 at 15:05
• for 05/02/2012 I get 3, 06/02/2012 I get 6.for 11/02/2012 I get 5. – Hari Gillala Commented Jan 31, 2012 at 15:17

You're using getDate() (= day in the month) instead of getDay() (= day of the week) at the else block. Replace getDate with getDay:

CallbackDateNumber = new Date().getDay();

Your dates need to be in MM/DD/YYYY format. It's parsing 05/02/2012 as May 2, 2012 and 06/02/2012 as June 2, 2012.
