Can the Umm al Qura calendar serve as a global Islamic calendar?

Over the past 50 years, the Arab League, the Organization of the Islamic Conference (OIC) and other similar bodies presented their member States with over a half-dozen proposals aiming at the establishment of a common Islamic calendar. Although none of these proposals was adopted, efforts in search of a solution that could be satisfactory to all interested parties continue to this day. For its part, the Fiqh Council of North America (FCNA) was also regularly confronted with the responsibility of telling its Muslim American audience when to start fasting, when to celebrate «eid al-Fitr», «eid al-Adha», etc. After several years of study of the legal issues involved, it reached a decision, which it announced in August 2006, to use henceforth a pre-calculated Islamic calendar, taking into consideration the sightability of the new moon anywhere on Earth.

First, it retains the well-known principle of unicity of horizons (matâli’) which states that it is sufficient to observe the new moon anywhere on Earth, in order to declare the beginning of a new lunar month, applicable in all areas in which the information is received. Second, it uses the International date line (IDL) or Greenwich Mean Time (GMT) as its conventional point of reference to conduct its analysis.

Based on the maps of sightability of the new moon in the various regions of Earth, which are now regularly prepared by professional astronomers, (2) FCNA reached the conclusion that when the conjunction took place before 12:00 noon (GMT), there was enough time left for the new moon to be seen in numerous areas on Earth where sunset took place long before sunset in North America. Since the criteria of sightability of the new moon were met in these areas, the new moon would be observed (or could have been observed if weather conditions had been adequate) long before sunset in North America. Therefore, the requirements of sightability of the new moon as set by the shari’ah would be respected, and the new lunar month could begin in North America on sunset of the same day. On the other hand, if the conjunction took place after 12:00 noon GMT, the month would begin in North America on sunset of the following day.

The FCNA decision aroused much interest in many Muslim countries, because it elegantly met the requirements of the traditional interpretation of the shari’ah, while making use of the state-of-the art know-how in the field of astronomy to respond to the needs of the modern age. It was thought that this solution could be applicable in other Muslim countries, and could give them a chance to adopt the same pre-calculated Islamic calendar (prepared on an annual basis, long in advance), in order to fulfill all the religious duties as well as to manage all other tasks.

An international conference was thus held in Morocco, in November 2006, to study the issues involved, with the participation of astronomers from Saudi Arabia, Egypt, Jordan, UAE, Iran, Guinea, Libya, Morocco, and the USA. The overwhelming majority of the participants, including Saudi, Egypt, and Iran astronomers agreed that the calendar adopted by Fiqh Council of North America could be used as a Global Islamic Calendar.
