有时我们在网页设计中常常会用到显示阴历(农历)日期，这时可能很多人会想到通过复杂的程序来实现，其实我们完全可以通过JS代码来实现，下面的JS代码就是可以实现显示阴历(农历)日期，你可以把下面的代码复制保存为JS在网页当中调用就可以了，代码如下：

function RunGLNL(){

var today=new Date();

var d=new Array("星期日","星期一","星期二","星期三","星期四","星期五","星期六");

var DDDD=(today.getYear()<100 ?

today.getYear()+1900:today.getYear())+"年"+(today.getMonth()+1)+"月"+today.getDate()+"日";

DDDD = DDDD + " " + d[today.getDay()];

DDDD = DDDD+ " " + (CnDateofDateStr(today));

//DDDD = DDDD+ " " + SolarTerm(today);

document.write(DDDD);

}

function DaysNumberofDate(DateGL){

return parseInt((Date.parse(DateGL)-Date.parse(DateGL.getYear()+"/1/1"))/86400000)+1;

}
