浅谈先秦天文历法与《周易》“乾卦”及“五行”的关系——以“二月二龙抬头”为例

A preliminary research on the relationship between astronomy calendars and the "Qian hexagram",and "Five Elements" of Book of Changes:Taking dragon head raising on February 2nd as an example

通过确定“二月二”在西周历法中的阴历日期,以此为节点,按照西周实测历法推算出阴历1~6月东方“青龙”星宿在夜空中运行的位置,并与《周易》“乾卦”的卦辞做相互比较,发现天象与卦辞存在实际对照关系。这种时间与空间的抽象思维观念,是“五行”内容的重要组成部分。先秦天文历法是古代圣贤对浩瀚宇宙不断思索的智慧结晶!

By determining the lunar date of "February 2nd " in the Western Zhou calendar,the orbital morions of the "Azure Dragon" stars in the east night sky from January to June were calculated.Meanwhile,compared with the hexagram texts of the "Qian" in Book of Changes,the positive.correlation between astronomical phenomena and Qian hexagram texts have been proposed.The abstract conception of time and space is a crucial part of the ’Five Elements".The astronomical calendars in the pre-Qin period are the crystallization of the wisdom of the ancient sages in their infinite exploration of the vast universe!
