JavaScript : Date Object
Date object of Java Script is used to work with date and times.

var variablename=new Date( )
In the above new is a keyword which creates an instance of object and
Date() defines variablename as Date Object.
Example:
var d=new Date( )
In the above example, variable d is defined as Date object which has current
date and time as its initial value.
