JavaScript Date Object
Date Object
The Date object is used to work with dates and times.
Date objects are created with new Date().
There are four ways of instantiating a date:
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);
var d = new Date(milliseconds);
var d = new Date(dateString);
var d = new Date(year, month, day, hours, minutes, seconds, milliseconds);
For a tutorial about date and times, read our JavaScript Date Object tutorial.
