hey,

This is how you create a date object and store it in a variable:

var now = new Date();

The "new Date()" part of the above statement creates the date object.
The "var now =" part causes the date object to be stored in the variable named "now".

How To Extract Information From that Date Object

Lots of information can be extracted from a date object. In this tutorial, 
we ll extract only what we ll need:

var hour        = now.getHours();
var minute      = now.getMinutes();
var second      = now.getSeconds();
var monthnumber = now.getMonth();
var monthday    = now.getDate();
var year        = now.getYear();

Notice that the name of the variable containing the date object and a period are
 followed by the function name. The function extracts the information from the date
 object and stores it in the variable named on the left of the equal sign.

All of the function names are intuitive except getDate(), which gets the day of 
the month rather than a date. Do not confuse "getDate()" with "new Date()" 
-- the former, as stated, extracts the day of the month from a date object.
 The latter creates the date object itself.
