javascript is creating date wrong month

In my code, I create Date by this line:

var date = new Date('2012', '01', '20')

and then using:

alert(date);

I get the result:

I don't really understand why not Jan instead of Feb?

Answer 1

The "Month" part of var date = new Date('2012', '01', '20'); is zero-indexed.

Start counting at 0, and you got your month. (So, January is 0, Feb 1, etc.)

Also, while JavaScript does accept strings as parameters, you should be using integers, as the documentation suggests:

Answer 2

Javascript Date Object's Month is 0 indexed. http://www.w3schools.com/jsref/jsref_obj_date.asp. put 0 instead of 1 for Jan
