干支是天干,地支的合称，干和支组合后用于纪年。

就是将十天干和十二地支按顺序搭配组合成干支,用于纪年.

把干支顺序相配正好六十为一周，周而复始，循环记录，永无止尽。

十大天干：甲 乙 丙 丁 戊 己 庚 辛 壬 癸

十二地支：子(鼠) 丑(牛) 寅(虎) 卯(兔) 辰(龙) 巳(蛇) 午(马) 未(羊) 申(猴) 酉(鸡) 戌(狗) 亥(猪)

十大天干、十二地支对应编号.如下：

甲 乙 丙 丁 戊 己 庚 辛 壬 癸

4 5 6 7 8 9 0 1 2 3

子 丑 寅 卯 辰 巳 午 未 申 酉 戌 亥

4 5 6 7 8 9 10 11 0 1 2 3

把天干和地支两者组合在一起就是相应年份的干支纪年法表示：如2018年干支纪年法表示便是”戊戌“是狗年.

附上代码：
