Create Date Object In JavaScript
In JavaScript, the date object is based on a timestamp of milliseconds elapsed since the epoch.
The date output will use the time zone of the local device which is normally the web browser.
A date object is created via the date constructor. An optional date string can be passed to the constructor before or after the date object is created. Alternatively, up to 7 numbers can be used to specify year, month, day, hour, minute, second and millisecond.
