51單片機陽歷轉農歷（僅僅是陽歷轉陰歷例程）

ID:310680 · 發表于 2018-12-30 22:31

之前要做一個萬年歷，從論壇上輾轉多處，最終發現以下這個陽歷轉換陰歷的程序比較簡單，數據帶入可以直接使用，不過測試發現轉換有問題，后面進行仿真調試找到問題所在，從而進而修改。不知道是我復制出錯，還是自己不經意間修改才導致問題出現，已經修復，需要陽歷轉陰歷的可以拿去。找不到具體來源，因此無法標志引用鏈接地址，如有侵權，聯系刪除。
問題所在：在SPDATE GetSpringDay(uchar GreYear,uchar GreMon,uchar GreDay)函數里面的參數定義，把Offset1定義為uchar類型，后面計算時Offset1數值溢出，將uchar改為uint后，數據不在溢出，進行上機測試，轉換成功。

首先要能記住十大天干和十二地支，
十天干：甲、乙、丙、丁、戊、己、庚、辛、壬、癸；
十二地支：子、丑、寅、卯、辰、巳、午、未、申、酉、戌、亥；
天干地支紀年法首先是天干在前，地支在后，比如今年2005就為－乙酉年，先來算算天干，
有個公式：
4、 5、 6、 7、 8、 9、 0、 1、 2、 3 對應的十天干就是
甲、乙、丙、丁、戊、己、庚、辛、壬、癸，
數字為年代的最后的一位數字，比如今年是2005，最后一位是5，對應的天干就是乙；
地支的算法：用年代數除以12，后面的余數就代表某個地支，
余數分別為：4、 5、 6、 7、 8、 9、 10、 11、 0（能整除）、1、 2、3.
代表地支為：子、丑、寅、卯、辰、巳、午、未、申、酉、戌、亥.
比如2005年為例：年代末尾數為5，對應的天干為乙，2005除以12，余數為1，對應的地支為酉，所以2005年為乙酉年。

前段時間用STC15L104W改了一個時鐘，增加了農歷顯示功能，參照了你的程序，但是文件大小超出了范圍，只好想辦法精簡程序，發現如果農歷年和陽歷不是同一年，可以遞歸調用本函數 GetSpringDay(GreYear+1, GreMon+12, GreDay)，代碼會少30%，這個判斷就不需要了:  if(F) //春節在公歷日期后{ ……} 。
具體代碼如下：

typedef unsigned int u16;  //16位無符號整型數
typedef unsigned char u8;  //8位無符號整型數

u8 dn(u8 yy,u8 mm,u8 dd);                                  //公歷轉農歷函數
u8 temp;
u8 NonY=0;                                                    //農歷年
u8 NonM=0;                                                    //農歷月
u8 NonD=0;                                                    //農歷日

u16 nday[]={0,31,59,90,120,151,181,212,243,273,304,334,365,396};    //第n-1月有多少天

//公歷年對應的農歷數據,每年三字節,
//格式第一字節BIT7-4 位表示閏月月份,值為0 為無閏月,BIT3-0 對應農歷第1-4 月的大小
//第二字節BIT7-0 對應農歷第5-12 月大小,第三字節BIT7 表示農歷第13 個月大小

感謝兩位版主的分享。

星期也可以通過日期來計算的，而且算法簡單（蔡勒Zeller公式）。

基姆拉爾森星期計算公式& 蔡勒星期計算公式，其實都是大同小異的
