/*****
* 1.冬至所在的UTC日期保存在A[0],根據(jù)"規(guī)定1"得知在A[0]之前(含A[0])的那個UTC朔日定為年首日期
* 冬至之后的中氣分保存在A[1],A[2],A[3]...A[13],其中A[12]又回到了冬至,共計算13次中氣
* 2.連續(xù)計算冬至后14個朔日,即起算時間時A[0]+1 14個朔日編號為0,1...12,保存在C[0],C[1]...C[13]
* 這14個朔日表示編號為0月,1月,...12月0月的各月終止日期,但要注意實際終止日是新月初一,不屬本月
* 這14個朔日同樣表示編號為1月,2月...的開始日期
* 設(shè)某月編號為n,那么開始日期為C[n-1],結(jié)束日期為C[n],如果每月都含中氣,該月所含的中氣為A[n]
* 注:為了全總計算出13個月的大小月情況,須算出14個朔日。 3.閏年判斷:含有13個月的年份是閏年 當?shù)?3月(月編號12月)終止日期大于冬至日,
* 即C[12]〉A(chǔ)[12], 那么該月是新年,本年沒月12月,本年共12個月
* 當?shù)?3月(月編號12月)終止日期小等于冬至日,即C[12]≤A[12],那么該月是本年的有效月份,本年共13個月 4.閏年中處理閏月:
* 13個月中至少1個月份無中氣,首個無中氣的月置閏,在n=1...12月中找到閏月,即C[n]≤A[n]
* 從農(nóng)歷年首的定義知道,0月一定含有中氣冬至,所以不可能是閏月。 首月有時很貪心,除冬至外還可能再吃掉本年或前年的另一個中氣
* 定出閏月后,該月及以后的月編號減1 5.以上所述的月編號不是日常生活中說的"正月","二月"等月名稱:
* 如果"建子",0月為首月,如果"建寅",2月的月名"正月",3月是"二月",其余類推
