Date Object Functions

The JavaScript Date object stores the time and date and can be used to manipulate dates and perform date conversions. There are several ways to create a Date object. Invoked without arguments, the new Date object contains the time and date of its creation:

Date object functions operate only on JavaScript Date objects, created with the Date() constructor. If an object is not a JavaScript Date object, the corresponding Java function will be used instead of the JavaScript function. 
var now = new Date() // Thu Jun 12 15:14:51 EDT 2008

You can also create a Date object by specifying elapsed milliseconds from January 1, 1970 (the Unix epoch) or from individual date parts:

var due_date = new Date(800000000000);
// Tue May 09 02:13:20 EDT 1995

var due_date = new Date(1988,0,10);
// Sun Jan 10 00:00:00 EST 1988
Scripts also have access to the java.util.Date object.

The following topics describe methods in the Date object for manipulating date fields.
