1900年至2100年公历、农历互转Js代码

调用代码示例Demo
农历:冬月初九;甲午年丙子月乙亥日(马年)

上述显示的demo简单代码:


<script src="http://www.jjonline.cn/Public/Js/calendar.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
 var lunar = calendar.solar2lunar();
 $('.solarlunar').html('<strong>调用代码示例Demo</strong><br />农历:'+lunar.IMonthCn+lunar.IDayCn+';'+lunar.gzYear+'年'+lunar.gzMonth+'月'+lunar.gzDay+'日('+lunar.Animal+'年)');
});
</script>

最近在研究农历、公历的互转算法,墨迹了两三天发现我国农历(太阴历、月亮历)并没有世界通用的公历(太阳历)那么有规律性;我国农历的一些原数据并没有一个固定的算法可以通过程序产生,只能由天文台测定后提供,所以一般的所谓“万年历”都是采用“查表法”获取农历数据而产生的;这也就限定了“万年历”的区间范围。如:下方是360提供的一个万年历,这个万年历就只能查询1901年至2100年的公历、农历以及二十四节气等数据;更古老的或者说更遥远的时间就无法提供。

在网络中找了找相关的素材资料,要么老旧、要么有稍许错误,又把我搞烦了,遂自己写了一个可查询、互转1900年至2100年区间农历与公历的javascript库;本库所有农历数据来源于香港天文台(地址:http://data.weather.gov.hk/gts/time/conversion1_text_c.htm);本来想找紫金山天文台的数据的,结果硬是没找着有200年区间的农历数据的网页。

源数据经过抓取以及匹配获得Js里查表法所需要用的“表”,剩下的就是一些常规的js算法代码了,没什么技术含量;就不多啰嗦了。

调用方法,详细本文开头的Demo示例已经很清楚了吧~还是cp下:

/**农历年月日转公历年月日**/
calendar.lunar2solar(1987,9,10);
//调用以上方法后返回类似如下object(json)具体以上就不需要解释了吧!
//c开通的是公历各属性值 l开头的自然就是农历咯 gz开头的就是天干地支纪年的数据啦~
