搜索了好几个python实现的万年历多有部分时间有问题，好多是来自这个代码：
#!/usr/bin/env python
# -*- coding: utf-8 -*-
'''
Usage: ccal Month [4-Digit-Year]
or: ccal 4-Digit-Year Month
This Python script is to show Solar and Lunar calender at the
same time. You need to have Python (2.0 or above) installed.
Acceptable date range: 1900/2 -- 2049/12
Output contains Chinese characters (mainland GB2312 encoding),
must be viewed in a Chinese-enabled system or "cxterm" etc.

这个也有问题（1989年8月的数据转换成农历就有问题）
看了好几个程序，发现实现这个并不需要什么NB的算法（好像也不存在这样的算法）可以直接实现阳历转为阴历的，都是记录了一堆阴历的数据，然后根据和基本时间来算相差几天来计算的，所有阴历数据的正确性决定了这个程序的正确性。
同学给了一个lua的程序，我试了一下，还没有找到错误的，先直接给上程序（直接从lua转成python的，写的比较乱）
