Introduction

Muslim people regularly get puzzled at the inability of the Islamic calendar to predict precisely, well in advance, the day on which major Islamic events are to take place, such as the first day of ramadan, or eid al-fitr, or eid al-adha, or the first day of the new Islamic year. They may even get annoyed because they cannot arrange in advance such ordinary things as taking a few days off from work on such occasions, making hotel bookings or flight reservations, or avoiding to take business or trip commitments on such dates.

The Islamic calendar’s shortcomings are indeed severe, since the data it shows each month differs from one Muslim country to another, and the information it provides does not extend beyond the current month. For instance, the first day of « ramadan » 1427 corresponded to Saturday, September 23, 2006 in 20 countries ; Sunday, September 24 in 46 countries ; and Monday, September 25 in 5 countries. (1) This situation is in no way unusual, but can be observed every month.

Nowadays, the Muslims use the Gregorian calendar to meet all their needs, and only care about Islamic dates on momentous Islamic occasions. However, the Islamic calendar only lost its usefulness when Muslim theologians disconnected it from its astronomical, conceptual and methodological moorings, early in the 7th century. It could fulfill all the basic functions of a calendar, and meet all the needs of modern man, within the Muslim community, on a worldwide basis, if it were prepared using the applicable scientific concepts, methods and parameters developed in astronomy.

Cadi Ahmad Shakir, President of the Egyptian Supreme Court of the Shari’ah, explained in a famous 1939 study that there was absolutely no obstacle, on the theological level, to the establishment of such an Islamic calendar, using astronomical calculations. (2)

In 2004, renowned jurist Yusuf al-Qaradawi announced his full support to Shakir’s analysis and conclusions. (3) For its part, the Fiqh Council of North America (FCNA), acting independently, presented in 2006 an ingenious, well thought-out methodology which permits the adoption of a pre-calculated calendar, while meeting all the requirements of the Shari’ah (4).

Astronomical considerations

The lunar calendar is based on a year of 12 months adding up to 354.37 days. Each lunar month begins at the time of the monthly “conjunction”, when the Moon is located on a straight line between the Earth and the Sun. The month is defined as the average duration of a rotation of the Moon around the Earth (29.53 days). The astronomers formulated the convention, over two thousands years ago, that months of 30 days and 29 days would succeed each other, adding up over two successive months to 59 full days. This left only a small monthly variation of 44 mn to account for, which added up to a total of 24 hours (i.e. the equivalent of one full day) in 2.73 years. To settle accounts, it was sufficient to add one day every three years to the lunar calendar, in the same way that one adds one day to the Gregorian calendar, every four years.

The Islamic calendar, however, is based on a different set of conventions. When the Messenger was asked for a method to determine the beginning of the month of fasting, he recommended to the faithful to begin fasting with the observation of the new moon (on the evening of the 29th day of sha’aban) and to end fasting with the new moon (of the month of shawal). “If the crescent is not visible (because of the clouds), count to 30 days”.

Thereafter, each Islamic State proceeded with its own monthly observation of the new moon (or, failing that, awaited the completion of 30 days) before declaring the beginning of a new month on its territory, instead of using a pre-calculated calendar, as computed by professional astronomers.

But, the lunar crescent becomes really visible only some 18 hours after the conjunction, and only subject to the existence of a number of favourable conditions relative to weather, time, geographic location, as well as various astronomical parameters… According to the months and seasons, the favourable conditions of observation of the new moon will be met in different sites on Earth.

Theological considerations

The Qor’an prohibits nowhere the use of astronomical calculations for the establishment of a pre-calculated calendar. The procedure is therefore perfectly and undisputably licit. Numerous theologians in the early years of Islam saw no contradiction between the Messenger’s teachings and the use of astronomical calculations to determine the beginnings of lunar months. (5) The dynasty of Fatimids in Egypt used a pre-calculated calendar over a period of two centuries, between the 10th and 12th centuries, before a change of political regime reactivated the procedure of observation of the new moon.

But the majority of Muslim theologians insist nowadays that, no matter what, one can’t go against the Messenger’s teachings. They interpret his recommendation concerning the observation of ramadan’s new moon as if it were part of the fundamental Islamic dogma. It would be utterly wrong, in their view, to use a calendar based on the conjunction, because one would start fasting, end fasting, and celebrate all other important Islamic events about two days earlier than would be the case, if the procedure of observation of the new moon were applied.

However, many Islamic thinkers insist that the Messenger’s recommendation to the faithful was merely adapted to the culture of the times. It should not be confused with the acts of worship. (6)

The Saudi authorities must share this view, somehow, since the country gave up in 1999 the procedure of observation of the new moon, to substitute to it a procedure based on the calculation of the schedules of sunset and moonset at the coordinates of Mecca, on the evening of the 29th day of each month. If the sun sets before the moon, this signals the beginning of the new month. In the opposite case, the month-in-progress lasts 30 days. This procedure has little to do with the observation of the new moon. (7)

One should also note that, during long periods of Islamic history, the hadith under discussion was not interpreted to mean the visual observation of a new moon, but only the acquisition of information, according to credible sources, that the month had begun. This opens entirely different vistas in the discussion of this question. (6)

As for the hadith of the Prophet according to which the Bedouins can neither read nor count, and must thus avoid using (astronomical) calculations, Ibn Taymiya observes that the argument may have been justified at the beginning of the 7th century, but he questions whether it could still apply to Muslims centuries later, after they had been at the vanguard of development of scientific knowledge, including in the field of astronomy.

Sheikh Abdul Muhsen Al-Obaikan, a Councilor in the Ministry of Justice of Saudi Arabia, is clearly favourable to the use of modern technology to determine the beginning of months. He says : « Using the naked eye to determine the beginning and end of Ramadan is primitive in an age of modern science and technology. There is no other way to put it. It’s pure backwardness.” » (8)
