Javascript Countdown doesn't work
<p>Everytime I reload this page <a href="http://prince27.bplaced.net/Prince27-Website/html/slider_true.html" rel="nofollow">http://prince27.bplaced.net/Prince27-Website/html/slider_true.html</a>, the countdown starts all over again. What did I do wrong?</p>

<p>I've set the endDate to 20 september 2012 and calculated the milliseconds between now &amp; endDate.</p>

<pre><code>var today = new Date();

var endDate = new Date("20/09/2012"); //set the date you want timer to end
var diffMs = (280800000); // milliseconds between now &amp; endDate
var diffDays = Math.round(diffMs / 86400000); // days
var diffHrs = Math.round((diffMs % 86400000) / 3600000); // hours
var diffMins = Math.round(((diffMs % 86400000) % 3600000) / 60000); // minutes
var diffSecs = Math.floor((((diffMs % 86400000) % 3600000) % 60000) / 1000);
</code></pre>
