Creating date with numbers (new Date(2012, 03, …) gives wrong month (+1)

I have this function:

function myFunction(){
 var d = new Date(2012,9,1);
var x = document.getElementById("demo");//some element demo

x.innerHTML=d.getDay();

}

I am trying to get the weekday on 1 date of any month . The code is above(an example).
Isn’t this supposed to return a saturday that is 6 as its value? It doesn’t give correct value. It gives 1 in this case.It seems simple but i am missing something.
am i misinterpreting the equation ?

Please tell.

some edit: Although it is a little bit different but still it was on the same line.

 function myFunction()
{

for(i=0;i<12;i++){

  var d = new Date(2012,i,0);

  k=i+1;

  var x = document.getElementById(""+k);

   x.innerHTML=d.getDate()+" "+i;


  }

}

This function writes the particular ids 12 total in no. and i get the following output:

31 0

31 1

29 2

31 3

30 4

31 5

30 6

31 7

31 8

30 9

31 10

30 11

That is not correct.

The function above is generating out months and corresponding days.

Answer 1

You forgot that when creating a new Date object, the month parameter takes a number between 0-11. September is 8. Try changing that to 8, and your day will return 6, which is Saturday.

Your corrected code:

function myFunction(){
var d = new Date(2012,8,1);
var x = document.getElementById("demo");//some element demo

x.innerHTML=d.getDay();

}
