干支纪年是由天干和地支两部分组成.其中天干分为甲、乙、丙、丁、戊、己、庚、辛、壬、癸,地支分为子、丑、寅、卯、辰、巳、午、未、申、酉、戌、亥.每一个干支纪年的天干、地支是按固定次序成一一对应的,从甲子开始,接着为乙丑、丙寅……,天干轮完后,又从第一个开始循环,地支也一样. 干支纪年的周期是60年.以甲子年为例,从第一个甲子年到第二个甲子年,天干和地支都应轮各自周期的整数倍.因天干的周期为10年,地支的周期为12年,又10与12的最小公倍数为60,所以从第一个甲子年到第二个甲子年至少要60年,即干支纪年的周期应为60年.
The dry branch age consists of two parts: Heavenly Stems and Earthly Branches. Heavenly Stems are divided into A, B, C, D, E, J, G, S, 壬, and 癸, and Earthly Branches are divided into Sub, Ugly, Uygur, Uygur, Chen, and Zang. After the Heavenly Steadier, the Heavenly Stems and Earthly Branches of each branch of the dry-bearing branch are in one-to-one correspondence in a fixed order. From the first cycle to the beginning, the same is true for the earthly branches. The cycle of the dry branches is 60 years. Take Jiazi Year as an example. From the first Jiazi year to the second Jiazi year, both the Heavenly Stems and the Earthly branches should be rounded to integer multiples. Since the cycle of Heavenly Stems is 10 years, the period of Earthly Branches is 12 years, and the least common multiple of 10 and 12 is 60, so the period from the first Year to the Second Year must be at least 60 years, that is, the period of the dry branch age should be 60 years.
