【js】阳历换算农历日期(1900

引言

前段时间仿做了一个win10的日历，其中涉及到阳历转换成农历的问题，当时顺手百度了一个js代码提供这个功能，但是不知道为什么其中有一段代码将2020年之后日期的屏蔽掉了，我将这个代码删除之后发现可以继续计算，当时没有多想，事后发现2020年之后的计算结果全是错误的

原因

农历定义为：农历取月相的变化周期即朔望月为月的长度，加入干支历“二十四节气”成分，参考太阳回归年为年的长度，通过设置闰月以使平均历年与回归年相适应

其中二十四节气将太阳角度划分为二十四等份，而这需要天文台的数据支持，也就是说每一年的农历都将会不一样，所以并没有唯一的算法可以直接算出所有的日期

农历都是采用“查表法”获取农历数据而产生的，也就是所谓的万年历

而不同版本的万年历是有界限的，流传较多的为紫金山天文台发布的截至2020年版本：在这里插入图片描述

此次出现错误问题所使用的代码是从1921开始到2020截至，为了继续使用我又从别的地方找的数据填上了两年，即截止到2022年

之后又在网上找了找，在GitHub找到一个大佬写的算法，使用的是香港天文台的年历数据，支持1900-2100年的农历换算算法的github地址.

为了复用原先写的代码我又加上了几个函数
