占月宿何星法第四

常以月將加卯爲地上乙所得星右行,如今日數止,即月宿星也。正月一日宿在室,二日在壁,三日在奎,四日在婁,以次逆行,空月盡日,月宿在壁,二月一日月宿在奎,至月盡日,月宿在婁,三月一日宿在胃,四月一日在畢,五月一日在井,六月一日在柳,七月一日在張,八月一日在角,九月一日在氐,十月一日在心,十一月一日在斗,十二月一日在女,若閏月朔,宿後一宿,是也。假令正月,閏壁,是也。

假令二月,五日,以魁臨卯,乙上見奎星,當唱言奎一,婁二,胃三,昴四,畢五,則爲月宿星日在畢也。十二月皆持月將臨卯,取乙上神所得星右行數。唯正月獨卯上星數右行,不從乙也。假令正月三日登明臨卯,卯上見營室數右行,營室一,東壁二,奎三,爲月宿星得奎也。他准此。
