JS Date Object
Date object
The Date object is used to work with dates and times.
Create a Date object: new Date().
The following four methods also create a Date object:
var d = new Date();
var d = new Date(milliseconds);
var d = new Date(dateString);
var d = new Date(year, month, day, hours, minutes, seconds, milliseconds);
