(javascript)常用农历（12生肖年，天干地支，节气）

今天碰到页面需要加上农历和公历同时显示的功能要求，搜索下网络，找到一个网页不过现在找不到地址了。希望给大家一点帮助。
贴代码如下：

//--------------------显示中国农历---------------------
//-------------  create date:2007-10-9 ----------------
//-------------     call  example      ----------------
//显示当前时间
//function setCalendar()
//{
//    document.write("<table border='1' cellspacing='3' width='180' bordercolor='#009B00' bgcolor='#FFFFFF' height='110' cellpadding='2'");
//    document.write("<tr><td align='center'><b>"+YYMMDD());
//    document.write(weekday());
//    document.write("<br>"+solarDay2()+"</td></tr></table>");
//}
//-------------            end   example             ----------------
