Your page doesn't load right for me. In general though, to display just the 2nd countdown in the demo, the HTML would look like this:
Code:
<div id="countdowncontainer2"></div>
<script type="text/javascript">
var currentyear=new Date().getFullYear()
//dynamically get this Christmas' year value. If Christmas already passed, then year=current year+1
var thischristmasyear=(new Date().getMonth()>=11 && new Date().getDate()>25)? currentyear+1 : currentyear
var christmas=new cdtime("countdowncontainer2", "December 25, "+thischristmasyear+" 0:0:00")
christmas.displaycountdown("days", formatresults2)
</script>
