万年历的农历的计算方法

//C51写的公历转农历和星期 
#define uchar unsigned char 
#define uint unsigned int 
#include <intrins.h> 
/* 
公历年对应的农历数据,每年三字节, 
格式第一字节BIT7-4 位表示闰月月份,值为0 为无闰月,BIT3-0 对应农历第1-4 月的大小 
第二字节BIT7-0 对应农历第5-12 月大小,第三字节BIT7 表示农历第13 个月大小 
月份对应的位为1 表示本农历月大(30 天),为0 表示小(29 天) 
第三字节BIT6-5 表示春节的公历月份,BIT4-0 表示春节的公历日期
