setMonth(1) gives me March?

Why is setMonth(1) giving me March? I believe that 0=Jan, 1=Feb, 2=Mar

<!DOCTYPE html>
<html>
<head>
<script>
window.onload = init;

function init(){
var d = new Date();
d.setFullYear(2014);
d.setMonth(1);
d.setDate(1);

document.getElementById("demo").innerHTML = d;
}
</script>
</head>
<body>

<div id="demo"></div>

</body>
</html>

I get...

Sat Mar 01 2014 15:11:03 GMT-0600 (Central Standard Time)

I'm running Win7 Pro 64-bit and the clock and calendar seem to be correct.

Today is the 31st of January. When you d.setMonth(1); you are trying to set the date to the 31st of February. Since this date doesn't exist, it falls over to the 3rd of March.

Set the whole date when you initialise the object, don't try to change it piecemeal.
