Creating Date Object in JavaScript

We can create Date objects using the Date() constructor.
Different ways of initiating dates:
For current date and time: new Date()
For milliseconds: new Date(milliseconds)
For Date : new Date(dateString)

For Year, month, day, hours, minutes, seconds, milliseconds): new Date(year, month, day, hours, minutes, seconds, milliseconds)
If you don’t specify a parameter 0 to be passed in. Dates are calculated in milliseconds as of 01 January,1970 00:00:00 UTC
Examples of dates:
var tod = new Date()
var d1 = new Date(89,4,21)
var d2 = new Date(89,4,21,12,30,0)
