	sumwinMonth = getUTCMonth() + 1

最简单的代码:

比如:
今天是: <%=weekdayname(weekday(date()))%>

又比如:
2008年6月9日是:<%=weekdayname(weekday(#2008-6-9#))%>

两种方法,你捡哈
一,JS(客服端实现,可以自动按秒刷新)

<script language="javascript" type="text/javascript">
function showTime(type)
/*type参数为日期显示模式
1 yyyy-m-d H:m:s
2 yyyy年m月d日 H:m:s
3 yyyy年m月d日 星期 H:m:s
4 yyyy年m月d日 星期
*/
{
now=new Date();
hours = now.getHours();  //得到小时
minutes = now.getMinutes();  //得到分钟
seconds = now.getSeconds();  //得到秒

year=now.getYear();  //得到年份
month=now.getMonth()+1;  //得到月份
date=now.getDate();  //得到日期
day=now.getDay();  //得到星期数

//星期转换
if (type == 3 | type == 4) //日期显示模式为3或4才转换
{
if (day == 0) dayc = "星期日" 
if (day == 1) dayc = "星期一"
if (day == 2) dayc = "星期二"
if (day == 3) dayc = "星期三"
if (day == 4) dayc = "星期四"
if (day == 5) dayc = "星期五"
if (day == 6) dayc = "星期六"
}

if (type == 1) return (year + "-" + month + "-" + date + " " + hours + ":" + minutes + ":" + seconds)
if (type == 2) return (year + "年" + month + "月" + date + "日 " + hours + ":" + minutes + ":" + seconds)
if (type == 3) return (year + "年" + month + "月" + date + "日 " + dayc + " " + hours + ":" + minutes + ":" + seconds)
if (type == 4) return (year + "年" + month + "月" + date + "日 " + dayc)
}
//这句是用来显示的,可以在要显示的地方加一个ID为time的A标签
setInterval("document.getElementById('time').innerText=showTime(3)",1000)
</script>

二,Vbscript(服务端的)

//-----------------
//中文显示日期星期子程序
//2007-12-11
//-----------------
sub china_time
dim a,b,c
a = year(date)
b = month(date)
c = day(date)
response.write (a&"年"&b&"月"&c&"日"&" "& weekdayname(weekday(date)))
end sub
//在你要显示的地方直接调用过程就行,和三楼的一样

ls的JS脚本是可行的.lz可以测试一下(以html方式保存并运行),代码修改如下:

<script language="javascript" type="text/javascript">
//showTime(3);
//showTime(4);
function showTime(type)
/*type参数为日期显示模式
1 yyyy-m-d H:m:s
2 yyyy年m月d日 H:m:s
3 yyyy年m月d日 星期 H:m:s
4 yyyy年m月d日 星期
*/
{
now=new Date();
hours = now.getHours();  //得到小时
minutes = now.getMinutes();  //得到分钟
seconds = now.getSeconds();  //得到秒

year=now.getYear();  //得到年份
month=now.getMonth()+1;  //得到月份
date=now.getDate();  //得到日期
day=now.getDay();  //得到星期数

//星期转换
if (type == 3 || type == 4) //日期显示模式为3或4才转换
{
if (day == 0) dayc = "星期日" 
if (day == 1) dayc = "星期一"
if (day == 2) dayc = "星期二"
if (day == 3) dayc = "星期三"
if (day == 4) dayc = "星期四"
if (day == 5) dayc = "星期五"
if (day == 6) dayc = "星期六"
}

if (type == 1) return (year + "-" + month + "-" + date + " " + hours + ":" + minutes + ":" + seconds)
if (type == 2) return (year + "年" + month + "月" + date + "日 " + hours + ":" + minutes + ":" + seconds)

if (type == 3) return (year + "年" + month + "月" + date + "日 " + dayc + " " + hours + ":" + minutes + ":" + seconds);
//{document.write(year + "年" + month + "月" + date + "日 " + dayc + " " + hours + ":" + minutes + ":" + seconds);}
if (type == 4) {return (year + "年" + month + "月" + date + "日 " + dayc);
document.write(year + "年" + month + "月" + date + "日 " + dayc);}
}
//这句是用来显示的,可以在要显示的地方加一个ID为time的A标签
//setInterval("document.getElementById('time').innerText=showTime(3)",1000)
document.write("模式1   ",showTime(1),"<br>");
document.write("模式2   ",showTime(2),"<br>");
document.write("模式3可日期显示自动转换：   ",showTime(3),"<br>");
document.write("模式4可日期显示自动转换：    ",showTime(4),"<br>");
</script>
