前段时间做软件写了个公历转农历的函数,目前公开给大家参考,有兴趣的朋友可以在此基础上进一步完善其功能
/*------------农历转换函数-----------*/
char *GetDayOf(PSYSTEMTIME pSt)

/*天干名称*/
const char *cTianGan[] = {"甲","乙","丙","丁","戊","己","庚","辛","壬","癸"};
/*地支名称*/
const char *cDiZhi[] = {"子","丑","寅","卯","辰","巳","午",
"未","申","酉","戌","亥"};
/*属相名称*/
const char *cShuXiang[] = {"鼠","牛","虎","兔","龙","蛇",
"马","羊","猴","鸡","狗","猪"};
/*农历日期名*/
const char *cDayName[] = {"*","初一","初二","初三","初四","初五",
"初六","初七","初八","初九","初十",
"十一","十二","十三","十四","十五",
"十六","十七","十八","十九","二十",
"廿一","廿二","廿三","廿四","廿五",
"廿六","廿七","廿八","廿九","三十"};
/*农历月份名*/
const char *cMonName[] = {"*","正","二","三","四","五","六",
"七","八","九","十","十一","腊"};
/*公历每月前面的天数*/
