前言
輸出陰歷一直是個老大難的問題。由於陰歷日子沒有規律。所以這裏須要做的就是通過打表的算法做到輸出陰歷日子，可是非常多人都不太了解原理，我這裏就給大家送上了一個福利。把自己做好的基於打表的陰歷的日子的算法告訴大家！
正文
這個程序完畢了例如以下功能，輸入一個日子。詳細到年月日。就能夠實現把這個年月日的日期的陰歷給輸出出來。基於是打表的算法。
大家不用了解咋做的，僅僅須要調用output函數就能夠了
大家把前面的一些信息所有粘上，然後調用output函數就能輸出陰歷信息了
大致我調好的能夠使用的程序例如以下：
#include <stdio.h>
#include <time.h>
#include <string.h>
#include <iostream>
using namespace std;
unsigned int
//Sun_NY 記錄陽歷日離當年元旦的天數。
if ( ((LunarCalendarTable[year-1901] & 0x0060) >> 5) == 1)
Spring_NY = (LunarCalendarTable[year-1901] & 0x001F) - 1;
else
Spring_NY = (LunarCalendarTable[year-1901] & 0x001F) - 1 + 31;
Sun_NY = MonthAdd[month-1] + day - 1;
if ( (!(year % 4)) && (month > 2))
Sun_NY++;
//StaticDayCount記錄大小月的天數 29 或30
//index 記錄從哪個月開始來計算。
//flag 是用來對閏月的特殊處理。
//推斷陽歷日在春節前還是春節後
if (Sun_NY >= Spring_NY)//陽歷日在春節後（含春節那天）
{
Sun_NY -= Spring_NY;
month = 1;
index = 1;
flag = 0;
if ( ( LunarCalendarTable[year - 1901] & (0x80000 >> (index-1)) ) ==0)
StaticDayCount = 29;
else
StaticDayCount = 30;
while (Sun_NY >= StaticDayCount)
{
Sun_NY -= StaticDayCount;
index++;
if (month == ((LunarCalendarTable[year - 1901] & 0xF00000) >> 20) )
{
flag = ~flag;
if (flag == 0)
month++;
}
else
month++;
if ( ( LunarCalendarTable[year - 1901] & (0x80000 >> (index-1)) ) ==0)
StaticDayCount=29;
else
StaticDayCount=30;
}
day = Sun_NY + 1;
}
else //陽歷日在春節前
{
Spring_NY -= Sun_NY;
year--;
month = 12;
if ( ((LunarCalendarTable[year - 1901] & 0xF00000) >> 20) == 0)
index = 12;
else
index = 13;
flag = 0;
if ( ( LunarCalendarTable[year - 1901] & (0x80000 >> (index-1)) ) ==0)
StaticDayCount = 29;
else
StaticDayCount = 30;
while (Spring_NY > StaticDayCount)
{
Spring_NY -= StaticDayCount;
index--;
if (flag == 0)
month--;
if (month == ((LunarCalendarTable[year - 1901] & 0xF00000) >> 20))
flag = ~flag;
if ( ( LunarCalendarTable[year - 1901] & (0x80000 >> (index-1)) ) ==0)
StaticDayCount = 29;
else
StaticDayCount = 30;
}
day = StaticDayCount - Spring_NY + 1;
}
LunarCalendarDay |= day;
LunarCalendarDay |= (month << 6);
if (month == ((LunarCalendarTable[year - 1901] & 0xF00000) >> 20))
return 1;
else
return 0;
}
void output(int year,int month,int day)
{
const char *ChDay[] = {"*","初一","初二","初三","初四","初五",
"初六","初七","初八","初九","初十",

char str[13] = "";
strcat(str,"農歷");
if (LunarCalendar(year,month,day))
{
strcat(str,"閏");
strcat(str,ChMonth[(LunarCalendarDay & 0x3C0) >> 6]);
}
else
strcat(str,ChMonth[(LunarCalendarDay & 0x3C0) >> 6]);
strcat(str,"月");
strcat(str,ChDay[LunarCalendarDay & 0x3F]);
puts(str);
}
int main()
{
output(2016,3,25);
return 0;
