即C[12]〉A[12], 那么该月是新年,本年没月12月,本年共12个月 当第13月(月编号12月)终止日期小等于冬至日,即C[12]≤A[12],那么该月是本年的有效月份,本年共13个月 4.闰年中处理闰月: 13个月中至少1个月份无中气,首个无中气的月置闰,在n=1...12月中找到闰月,即C[n]≤A[n] 从农历年首的定义知道,0月一定含有中气冬至,所以不可能是闰月。 首月有时很贪心,除冬至外还可能再吃掉本年或前年的另一个中气 定出闰月后,该月及以后的月编号减1 5.以上所述的月编号不是日常生活中说的"正月","二月"等月名称: 如果"建子",0月为首月,如果"建寅",2月的月名"正月",3月是"二月",其余类推 *****/ var
