一段简单的倒计时代码
<script language="JavaScript">
var urodz= new Date("3/30/2005");
var s="今天离五一劳动节";
var now = new Date();
var ile = urodz.getTime() - now.getTime();
var dni = Math.floor(ile / (1000 * 60 * 60 * 24));
if (dni > 1)
document.write(""+s+"还有"+dni +"天")
else if (dni == 1)
document.write("只有2天啦！")
else if (dni == 0)
document.write("只有1天啦！")
else
document.write("好象已经过了哦！");
</script>

有时分秒的倒计时代码
-----------------------------

function show_student163_time(){
 window.setTimeout("show_student163_time()", 1000);
 BirthDay=new Date("04-01-2005");//改成你的计时日期
 today=new Date();
 timeold=(BirthDay.getTime()-today.getTime());
 sectimeold=timeold/1000
 secondsold=Math.floor(sectimeold);
 msPerDay=24*60*60*1000
 e_daysold=timeold/msPerDay
 daysold=Math.floor(e_daysold);
 e_hrsold=(e_daysold-daysold)*24;
 hrsold=Math.floor(e_hrsold);
 e_minsold=(e_hrsold-hrsold)*60;
 minsold=Math.floor((e_hrsold-hrsold)*60);
 seconds=Math.floor((e_minsold-minsold)*60);
 span_dt_dt.innerHTML=daysold+"天"+hrsold+"小时"+minsold+"分"+seconds+"秒" ;
 
}
show_student163_time();
