阳历到阴历的转换

/*************************************************************************************************** 哈尔滨市闲人无事发呆有限公司 鼓 捣 所 鼓捣总部 Q Q：958415720 Email:yiwanfuweng@126.com

说 明: 经过几天日子的鼓捣，弄出来了这个万年历阳历转换阴历的转换代码，由于网上很多的代码写的

很乱，起初也不懂关于一些天文的知识，看的迷糊，让我很是无奈就想还是自己写吧偶尔在网上 找到了一个PDF文档叫《公历与农历日期的转换》 让我明白了许多 从而就开始花了一天的时间写 出来了。希望想要做万年历的人拿去用 这是在VC++ 6.0 平台的 直接就可以移植到51,AVR,STM32等等上 的。
