John try the following code.

Code:
 
<script type="text/javascript"><!--
var now = new Date();
var Weekday = new Array("SUN","MON","TUE","WED","THU","FRI","SAT");
var Month = new Array("JAN","FEB","MAR","APR","MAY","JUN ","JUL","AUG","SEP","OCT","NOV","DEC");
document.write(Weekday[now.getDay()]+", "+Month[now.getMonth()]+" "+now.getDate()+", "+now.getFullYear());
//--></script>
Javascript is case sensitive. This means that the variable curDate and CurDate are different variables.
