Tabular Islamic Calendar

Authors: Wenceslao Segura González

We describe the arithmetic or computational Islamic calendar of medieval Muslim astronomers. We classify the different calendars of this type, also called tabular, finding the possible intercalation criteria. With the chronological Julian day, we obtain precise rules to convert this tabular calendar to the Julian or Gregorian calendar and vice versa. The Islamic tabular calendar is, on average, very close to astronomical reality; however, there is an error that is accumulative and that we determine precisely. This paper analyzes the Islamic era and its relationship with the pre-Islamic calendar that existed in Arabia before the arrival of Islam.
