4.8 DATE OBJECT

A Date is an object in JavaScript. An instance is created using the Date() object.

   var myDt = new Date();                  //returns current date
                                           //defined in the local machine
   var myDt = new Date(1926, 10, 23);      //pass date in the order—
                                           //year, month (0-11), day

Note that the month follows 0–11 rather than 1–12 convention. The time is optional. If it is required, pass additional parameters for hour, minutes, seconds and milliseconds.
