二十四节气形成年代考

Textual Research on the Forming Time of 24 Jieqi

二十四节气是我国传统历法的中心内容之一，它不但包含着我国古代劳动人民对农业气候的精辟认识，而且准确地反映了由于地球公转而形成的日地关系，成为掌握农事季节的可靠依据。本文从甲骨文、古籍文献入手，结合有关考古材料，考定二十四节气大致萌芽于夏商时期，在战国时期已基本形成，并于秦汉之时趋向完善并定型。

：24 Jieqi (one of the 24 solar terms, of approximately 15 days each, into which the lunar yera is divided, corresponding to the day on which the sun enters the 1st or 15th degree of one of the 12 zodiacal sign; each period being given an appropriate name indicating the obvious changes in nature at the time it comes round) is one of main content of Chinese traditional calendar. On the basis of oracle－ bone inscriptions and ancient documents and data from archaeology discoveries, this paper has a texture research on the forming time of 24 Jieqi and concludes that 24 Jieqi was in the embryonic stage in Xia and Shang periods and formed its principal part during the Warring States period and was finalized in Qin－ Han periods.
