New Date ("Month dd,yyyy hh:mm:ss");
New Date ("Month dd,yyyy");
New Date (YYYY,MTH,DD,HH,MM,SS);
New Date (YYYY,MTH,DD);
New Date (MS);

New Date (2006,0,12,22,19,35);

New Date (2006,0,12);

New Date (1137075575000);

Objdate.getyear () returns the year in two-bit or four-digit numbers depending on the browser
Objdate.getmonth ()
Objdate.getdate ()
Objdate.getday ()
Objdate.gethours ()
Objdate.getmilliseconds ().
..........

1. Two date object is directly subtracted, the result is millisecond difference!

2. Add and subtract any component:

Get out first.

Do the calculations

Then put it back with set;

1.date.tolocalestring ();

2.date.tolocaledatestring ();

2.date.tolocaletimestring ();

Copy Date Object
