说明：  万年历的完整算法。它首先计算出对应阳历月第一天对应是星期几，然后根据数据压缩算法确定，确定对应的阴历日期；而阴历节气，则有条件规律算法实现。
(Calendar complete algorithm. It first calculates the corresponding Yang calendar month first day correspondence is a few weeks, and then identify the corresponding to the lunar calendar date according to data compression algorithm to determine and lunar solar terms, condition rule algorithm.)
