How to init this jQuery countdown

Found out about this cool jQuery countdown

which is initialized as such:

<script type="text/javascript">
    $(function () {
        $('#countdown').countdown({until:$.countdown.UTCDate(-8, 2011,  1 - 1, 1), format: 'DHMS', layout:
            '<div id="timer">' + '<hr />'+
            '<div id="timer_days" class="t开发者_高级运维imer_numbers">{dnn}</div>'+
            '<div id="timer_hours" class="timer_numbers">{hnn}</div>'+
            '<div id="timer_mins" class="timer_numbers">{mnn}</div>'+
            '<div id="timer_seconds" class="timer_numbers">{snn}</div>'+
            '<div id="timer_labels">'+
            '<div id="timer_days_label" class="timer_labels">days</div>'+
            '<div id="timer_hours_label" class="timer_labels">hours</div>'+
            '<div id="timer_mins_label" class="timer_labels">mins</div>'+
            '<div id="timer_seconds_label" class="timer_labels">secs</div>'+
            '</div>'+
            '</div>'
    
        });
    });
</script>

Any idea how must I config it to countdown until 14th of July, and to also until 18:00PM?

The documentation for that plugin is here: http://keith-wood.name/countdown.html

The snippet there is:

var newYear = new Date(); 
newYear = new Date(newYear.getFullYear() + 1, 1 - 1, 1); 
$('#defaultCountdown').countdown({until: newYear}); 

That makes it countdown to the next new year. To count down to a particular date, set newyear = new Date(2011, 12-1, 25) (that's Christmas day).

So you could do:

$('#defaultCountdown').countdown({until: new Date(2011, 07-1, 4)});
