Date Object – JavaScript

learning javascript

The Date object is a datatype that is used to work with dates and times which is built into the JavaScript language.

Date objects are created with the new Date() that represents a single moment in time.

Once a Date object is created, you can allow a number of methods to operate on it.

This objects can be instantiated only by calling JavaScript Date as a constructor.


var dt = new Date();
var dt = new Date(milliseconds);
var dt = new Date(dateString);
var dt = new Date(year, month, day, hours, minutes, seconds, milliseconds);

After creating the instance of the Date object, you can get access all the methods of the object from the “dt” variable.

If we pass no argument in the Date(), then the constructor creates a JavaScript Date object for the current date and time according to the date of system settings.
