Jquery Countdown - weekly recurring time

Jquery Countdown - weekly recurring time

Hi there,

I am using a jquery countdown script by keith wood:  http://keith-wood.name/countdown.html

I'm trying to work out how to make it countdown to a fixed time every week (monday 8pm GMT).

the script is too big to add here but can be seen on the site and this is what I have from the example from the site: 

<script type="text/javascript">
$(function () {
var austDay = new Date();
austDay = new Date(austDay.getFullYear() + 1, 1 - 1, 26);
$('#defaultCountdown').countdown({until: austDay});
$('#year').text(austDay.getFullYear());
});
</script>

I cant make head or tail of how to make it work!

Please help

thanks
