About Time in Bahrain

In 1941, Bahrain Had More Than One Working Clock

For a place that had become an oil, shipping, aviation and communications hub, Bahrain entered the 1940s with a surprisingly basic coordination problem: important organizations were not all using the same time. Archival material later incorporated into the IANA time-zone record shows two competing standards in everyday business. Steamers of the British India company, Petroleum Concessions and Cable & Wireless used Greenwich time plus 3 hours 30 minutes. The Eastern Bank, British Overseas Airways Corporation and the Bahrain Petroleum Company used approximately GMT+3:23.

The seven-minute disagreement was large enough to matter. A ship departure, bank appointment, cable message or aircraft movement could acquire two different clock readings without anyone making an arithmetic error. Correspondence from the period even records that Bapco had changed its own practice because the previous arrangement was creating persistent confusion. Bahrain had clocks, telegraphy, an expanding oil industry and scheduled air connections, but no single civil standard accepted by all of them.

The historical zone model adds another layer. IANA represents Manama before standardization with local mean time at GMT+3:22:20. That figure corresponds almost exactly to longitude 50 degrees 35 minutes east, which is why it looks so oddly precise: it is essentially the longitude of Manama converted into time at the astronomical rate of four minutes per degree. Yet IANA also warns that there was no genuine island-wide standard before 1941. The local-mean-time value is therefore useful for computational reconstruction, not evidence that every office and company displayed 3:22:20 ahead of Greenwich.

Political Agent Reginald George Alban tried to resolve the problem. The surviving correspondence considered several possibilities, including a daylight-saving arrangement, before consensus formed around GMT+3:30. The government adopted that standard on 20 July 1941, and the organizations involved appear to have completed their changes by the beginning of August.

One detail should not be invented when converting timestamps from this period: the archival record does not give a precise hour at which every clock was changed on 20 July. IANA explicitly preserves that uncertainty. Treating the transition as if the entire island jumped simultaneously at midnight would give the database more precision than the historical evidence supports.

BOAC Asked for More Evening Light, and Half an Hour Was Added

The 1941 compromise survived for little more than two years. On 1 November 1943, BOAC asked for another change, proposing GMT+4 or even GMT+4:30 so that more usable daylight would fall at the end of the working day. The request came from an airline, not from an astronomical observatory. Aviation schedules and daylight were helping reshape the clock.

Bahrain adopted GMT+4 from 1 January 1944. Relative to the GMT+3:30 standard, the displayed time advanced by thirty minutes. As with the 1941 transition, the sources used by IANA do not supply an exact time of day for the change, so the date is secure in the current reconstruction while a minute-by-minute transition sequence is not.

The four-hour offset then lasted for almost three decades. In June 1972 the zone record returns Bahrain to GMT+3, while historical reporting connects the change with coordination with Saudi Arabia. That one-hour retreat produced the offset still used today. The sequence is unusual: rather than gradually converging on the nearest geographical hour, Bahrain moved from competing corporate clocks to +3:30, then +4, and finally +3.

The Pearling Year Began When the Sea Was Ready

For generations, one of the most important calendars in Bahrain could not be fixed simply by printing a date in advance. The main pearl-diving season, Al Ghus Al Kabir, depended on conditions in the Gulf. The UNESCO documentation for Bahrain's Pearling site describes a season that traditionally began in early June and continued until mid-September or early October. By the period documented by J. G. Lorimer in the early twentieth century, the opening had been pushed back toward mid-May.

The choice of season was physical rather than ceremonial. The deeper pearl banks had to become warm enough for men to remain repeatedly immersed without modern diving equipment. Strong seasonal shamal winds needed to subside, the water had to settle sufficiently for visibility to improve, and long summer daylight allowed crews to exploit the banks for more hours. Several environmental clocks therefore had to agree before the most intensive work could begin.

The departure itself was converted into an official public event. The boarding day, Al Rakbah, was traditionally announced by the ruler several days before the fleet left. Families then gathered along the shore as crews embarked. The return at the end of the main season, Al Qaffal, produced another large gathering. In Muharraq, departure and return were not just dates in a commercial schedule; they divided the social year into periods of presence and absence.

DANAT, the Bahrain Institute for Pearls and Gemstones, describes the typical expedition as lasting three or four months, usually from June into October. In some seasons more than 2,500 vessels sailed to the pearl banks. An economic system involving merchants, creditors, shipbuilders, captains, divers, rope pullers and families on shore was therefore synchronized around a comparatively narrow seasonal window.

Time contracted dramatically once a diver left the boat. DANAT gives a typical underwater interval of no more than one or two minutes. The profitable season might stretch across months, yet its basic productive act was repeated in breath-length episodes. Warm water and long daylight determined when the fleet could work; the diver's lungs determined how long each descent could last.

This was not a calendar in the sense of twelve identical blocks. Its boundaries responded to wind, sea temperature, visibility, daylight and official organization. The flexibility is precisely what made it useful. A fixed June date could be printed years in advance, but it could not guarantee that the Gulf was ready for sustained diving.

A Hadrah Turns the Tide into a Working Clock

Bahraini fishermen developed another system in which time is built directly into the equipment. The hadrah is a fixed intertidal fish trap, traditionally constructed from local materials and positioned so that its geometry works with the rise and fall of the sea. At high tide, fish move into shallow coastal water. As the water recedes, the trap guides them through a fence into progressively more confined sections until they can be collected near low tide.

The Bahrain Authority for Culture and Antiquities describes the three principal parts as the yad, a fence running out from shore, the hawsh or gathering enclosure, and the sir, the final catchment area near the low-water line. Heritage documentation for Qal'at al-Bahrain records examples reaching roughly 100 metres in length and 60 metres in width. Their placement, construction and maintenance required specialized local knowledge, and individual traps could be inherited or held as waqf property.

Academic fieldwork on Bahraini intertidal fisheries records catches being collected twice a day around low tide. The working schedule consequently moves with the sea rather than with a fixed hour on a wall clock. Low tide occurs later from one tidal cycle to the next, so the fisherman must follow a shifting environmental timetable. The trap is stationary; the usable hour moves.

One Recorded Boat Worked 130 Diving Days and Came Ashore Once

A surviving Government of Bahrain annual report from the late pearling era preserves the accounts of a boat financed through the court while an estate was being administered. Its crew consisted of a nakhuda, 29 divers, 35 pullers and one apprentice. During the season the vessel made only one visit to shore and accumulated 130 diving days. The account records provisions, advances, the sale of the pearls and the eventual division of proceeds among the different categories of crew.

Numbers like 130 days give a different scale to the familiar image of a diver making a one-minute descent. The working unit was repeated hundreds or thousands of times inside a season spent largely away from home. Food, water, physical recovery, opening oysters, moving between banks and maintaining the vessel all had to fit around the usable daylight and the sequence of dives.

Sound helped organize that time. Bahrain's pearling repertoire included songs associated with specific shipboard tasks such as strenuous rowing, handling sails and raising the anchor. The Bahrain Authority for Culture and Antiquities describes the nahham, the song leader, as part of this maritime world, with rhythm helping crews carry out collective work. Historical accounts of the tradition describe working hours extending from dawn toward sunset during the main season.

Not every piece of Bahraini sea music should be labelled a work song. The Pearling Path documentation distinguishes Fjiri, now recognized by UNESCO as intangible cultural heritage, from songs directly associated with labour, such as Midaf during rowing. That distinction makes the historical picture more precise. Some rhythms coordinated muscular effort at a particular moment; others gave crews a cultural and emotional language for months spent at sea. Both belonged to a maritime society whose year, day and individual dive were measured on radically different scales.
