    I found in the net the following script. It can help you.

    <html>
    <head>
    <title>Date substraction</title>
    </head>
    <body>
    <script language="JavaScript" type="text/javascript">
    <!--

    var myVar = prompt("Enter a future date: ")

    var user_date = Date.parse(myVar);
    var today_date = new Date();
    var diff_date = user_date - today_date;

    document.write(diff_date);
    //-->
    </script>
    </body>
    </html>

    Try this sample code, i think it helps you:

    <head>
	<script>
		function WriteDateTwoWeeksAgo () {
			var date = new Date ();
			var timeInMillisec = date.getTime ();	// the milliseconds elapsed since 01 January, 1970 00:00:00 UTC
			timeInMillisec -= 14 * 24 * 60 * 60 * 1000; 	// 14 days in milliseconds
			date.setTime (timeInMillisec);

			var twoWeeksAgoSpan = document.getElementById ("twoWeeksAgo");
			twoWeeksAgoSpan.innerHTML = date.toLocaleString ();
		}
	</script>
</head>
<body onload="WriteDateTwoWeeksAgo ()">
	<span id="twoWeeksAgo"></span>
</body>
    Code (markup):

    It was easier than I thought:

    var d = new Date();
    with (d) setDate(getDate()-14)
    document.write(d)
