By using a method for date objects, we can easily manipulate dates.

In the following example, we set a specific date for the Date object (August 9, 2008):

var mydate=new Date ()
mydate.setfullyear (2008,7,9)

Note: The parameters that represent the month are between 0 and 11. In other words, if you want to set the month to August, the argument should be 7.

In the following example, we set the Date object to the date after 5 days:

var mydate=new Date ()
mydate.setdate (Mydate.getdate () +5)

Note: If increasing the number of days changes the month or year, the date object automatically completes the conversion. Compare Date

Date objects can also be used to compare two dates.

The following code compares the current date with the August 9, 2008:

var mydate=new Date ();
Mydate.setfullyear (2008,8,9);

var today = new Date ();

if (mydate>today)
{
alert ("Today is before 9th August 2008");
}
else
{
alert ("Today was after 9th August 2008");
}
