Create a Date Object :

Date objects are created with the Date() constructor.

Syntax new Date() //default version, current date and time
new Date(milliseconds) //milliseconds since 1970/01/01
new Date("month day, year [hours:minutes:seconds]") //String Values
new Date(year, month, day[, hours, minutes, seconds]) /Integer ValuesHandling Events:
Example :
                    var today = new Date();
                    var  d1  = new Date(1364810808261);
                    var d2 = new Date("October 02, 2005 11:13:00");
                    var d3 = new Date(79,5,24,11,33,0); 
                    document.write(today+"<br/>");
                    document.write(d1+"<br/>");
                    document.write(d2+"<br/>");  
                    document.write(d3+"<br/>");
