通过对《武成》历日的分析 ,发现它对月相术语有一定的限制作用。既生霸、既死霸是相距半个月的相对两点 ,而既死霸只能在阴历 1 7～ 1 9日。“周历建子”并非金科玉律。很可能在西周时期并没有有效的置闰方法 ,因而并没有固定的“建正” ,而是在亥、子、丑、寅间游移。以上两点认识可能对于西周年代学研究是有益的。

There are some dates with lunar phases in the ancient literature Wucheng ,and these dates are the key information to determine the date of King Wu's conquest.An important argument is about the meaning of the special terms of lunar phases,Jishengba and Jisiba.An analysis to the literature shows that the meaning of the terms of lunar phases is limited by the context.Jishengba and Jisiba are opposite days in a month (half month differs);Jisiba can only locate on the 17～19th in a lunar month. It is usually considered that the first month contains the winter solstice day according to the calendar in the early Zhou dynasty.A discussion based on various astronomical information in that time shows that calendar of early Zhou can not set the winter solstice day in the first month perfectly.That day may appear in the 12 th ,1 st ,2 nd or even 3 rd month in a year,because of the error in determining the special day. The new understanding probably benefits the study on the chronology of West Zhou
