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 calculated the solar calendar the corresponding counterparts on the first day of the week, and then determine the data compression algorithm to determine the date corresponding to the lunar calendar and lunar cycle, the conditional law of algorithm implementation.)
