When reading the day number, in thiscase 7 th day of the week, or 5 th day ofthe month, read the day number forSabbaths by the shading (ignore thesolid line in the middle).For temple or creation days types, readthe day number between the solidlines. The day number is always set onthe daylight part of the day. Thedaylight part of the day is the same forevery day for Sabbaths, the Temple day,creation days, and Roman days. Onlywhich night is considered varies, or inthe case of a Roman day, six hours oneach side of the daylight part.Some Scriptures use one day type todefine another day type. Lev. 23:32says “on the 9 th day at setting” (this isthe sunrise-sunrise day type). Settinghappens in the middle of this day, andthe next setting in the middle of the10 th day. Thus Yom Kippur is definedfrom sunset to sunset.
