Countdown time help

I’m about to puke and bump my head on the keyboard . . . .
This jquery does not make sense at all.
I just want to edit the timer to expire on January 20 , 2012
Looks like this:
<script type="text/javascript">
$(function () {
  $('#countdown').countdown({until: new Date(2012, 12-10, 0)});
});
</script>
The following ends after 55 days .. etc hours/minutes/seconds
How is 12-10, 0 suppose to be 55 days ?
The only thing I tried figuring out is the “0” part it actually adds days.
But what about 12-10 ?
Any help is appreciated.
