Date and Time

The date object stores date and time and provides methods for managing it. Date objects are static and use a browser's default timezone to display the date as a full-text string.

To create date we use a new Date() constructor and can be created in the following ways.

new Date()
new Date(date string)
new Date(year,month)
new Date(year,month,day)
new Date(year,month,day,hours)
new Date(year,month,day,hours,minutes)
new Date(year,month,day,hours,minutes,seconds)
new Date(year,month,day,hours,minutes,seconds,ms)
new Date(milliseconds)

Months can be specified from 0 to 11, more than that will result in an overflow to the next year.
