/*************** 本類調用規則 ******************
******************************************************
1. 使用下面的函數來制作日歷結構
MakeCalendar(CALENDAR *m_cal,int y,int m,int d);//填充日期結構的年月日
2. 使用本函數來檢驗日歷是否合法
BOOL GongDataIsValid(CALENDAR m_date); //判斷公歷日期是否在界內
BOOL NongDataIsValid(CALENDAR m_date); //判斷農歷日期是否在界內
3. 將合法日歷進行公農歷相互轉換
CALENDAR ConvertToGongLi(CALENDAR m_nongli); //將農歷日期轉化為公歷日期
CALENDAR ConvertToNongLi(CALENDAR m_gongli); //將公歷日期轉化為農歷日期
4. 其他輔助函數：獲取星期；獲取公歷日期之間天數；獲取農歷日期之間天數
int GetWeekInfo(CALENDAR m_gongli); //根據公歷日期計算星期
int GetGongDays(CALENDAR m_start,CALENDAR m_end);//獲取公歷兩個日期之間的天數
int GetNongDays(CALENDAR m_start,CALENDAR m_end);//獲取農歷兩個日期之間的天數
int CompareTwoDate(CALENDAR m_fir,CALENDAR m_sec);//比較兩個日期的大小
CALENDAR GetCurGongDate(); //將當前公歷日期合成為結構
CString GetGanZhi(int m_nongyear); //獲取農歷年份的干支名稱
