The Date object is very useful because it carries various date information. The following statement creates an instance of the Date object, representing the current date:

var now = new Date();

The object now contains the current year, month, date, hour, minute, and second. Here is how to extract this information from the Date object: 

var currentYear = now.getYear();
var currentMonth = now.getMonth;
var currentDate = now.getDate();
var currentHour = now.getHour();
var currentMinute = now.getMinutes();
var currentSecond = now.getSeconds();

Similarly, you can set every Date item with the matching "set" method. For example, to advance the object by one hour, you would use the following syntax:

now.setHour(now.getHour() + 1);
