六十甲子是中國人民一個古老的發明創造,又稱六十花甲子,其最古老的用途是紀年、紀月、紀日、紀時。紀年爲60年一個周期,紀月爲5年一個周期,紀日爲60天一個周期,紀時爲5天一個周期。
天乾地支與六十甲子在中國古代的歷法中,甲、乙、丙、丁、戊、己、庚、辛、壬、癸被稱爲“十天乾”,子、醜、寅、卯、辰、巳、午、未、申、酉、戌、亥叫作“十二地支”。
十天乾和十二地支進行循環組郃:甲子、乙醜、丙寅......一直到癸亥,共得到60個組郃,稱爲六十甲子,如此周而複始,無窮無盡。年月日時都是60一個循環。
以天乾和地支按順序相配﹐即甲、乙、丙、丁、戊、己、庚、辛、壬、癸與子、醜、寅、卯、辰、巳、午、未、申、酉、戌、亥相組郃,從"甲子"起﹐到"癸亥"止﹐滿六十爲一周﹐稱爲"六十甲子"。亦稱"六十花甲子"。 又因起頭是“甲”字的有六組,所以也叫“六甲”。
