About Time in Sri Lanka

A Decade on the Wrong Side of the Clock

Sri Lanka, then still widely referenced by its colonial name Ceylon in older records, has shifted its official time zone several times since 1880, when it first settled on five and a half hours ahead of Greenwich. During the Second World War the clocks were pushed forward twice within a single year, first to six hours ahead in January 1942 as Japanese forces threatened invasion, then to six and a half hours ahead that September, before reverting after the war ended.

A more recent and more disruptive change came in 1996, when the government advanced clocks by a full hour to six and a half hours ahead of Greenwich as an emergency response to a severe electricity shortage, hoping extra evening daylight would ease demand on the power grid. The shift proved deeply unpopular, was not adopted in areas of the north and east then controlled by separatist forces during the civil war, and drew criticism from Buddhist clergy who argued it disrupted natural and spiritual rhythms. After a partial rollback to six hours ahead later that same year, the government finally abandoned the experiment entirely on April 15, 2006, returning Sri Lanka to five and a half hours ahead of Greenwich, the same offset it still keeps today, aligned with neighboring India.

A Calendar Ruled by the Moon: Poya Days

Roughly once a month, ordinarily on the day of the full moon, Sri Lanka observes a nationwide public holiday known as Poya. Rooted in the Buddhist lunar calendar and the practice of Uposatha observance, each of the year's twelve or thirteen Poya days carries its own name and commemorates a specific episode from the life of the Buddha or the history of Buddhism on the island, with shops and businesses closing and the sale of alcohol and meat restricted for the occasion.

Because the lunar and solar calendars drift apart from one another, the exact date of each Poya can shift slightly from year to year and is confirmed annually through official government gazette notices rather than fixed permanently on the civil calendar. This drift occasionally produces unusual years, such as 2026, when two full moons were set to fall within the same lunar month cycle, prompting an adjustment to the officially announced calendar after concerns were raised by senior Buddhist clergy about how the extra observance should be marked.

The Lighthouse That Became a Clock Tower

Standing at a busy junction in Colombo's Fort district, the Old Colombo Lighthouse is an unusual landmark, a working clock tower now located well inland rather than on the coast it once served. Construction was completed in February 1857, on a design credited to Emily Elizabeth Ward, wife of the colonial governor Sir Henry George Ward, making the 29 meter tower the tallest structure in Colombo at the time. Its clock mechanism, made by the same English firm that built the movement for the Westminster tower clock in London, had actually been commissioned decades earlier, in 1814, but sat unused in storage for economic reasons until it finally found a home in the new tower.

The tower took on a second role as an active lighthouse in 1867, its beam eventually strengthened enough to be seen roughly sixteen miles out to sea. As Colombo grew taller around it through the twentieth century, the surrounding buildings gradually blocked the light's usefulness to ships, and the lighthouse function was formally switched off in 1952. The clock, however, has never stopped keeping time for the city, and the tower still marks the hours from the middle of a busy traffic roundabout nearly one hundred seventy years after it was built.

9:20 in the Morning: The Tsunami Reaches Sri Lanka

On the morning of December 26, 2004, a massive undersea earthquake struck off the coast of Sumatra at roughly 7:59 local Indonesian time, sending a series of tsunami waves racing across the Indian Ocean toward Sri Lanka, more than 1,600 kilometers to the west. The first waves reached the island's east coast at around 8:45 a.m. local time, and within roughly thirty minutes the surge had wrapped around the coastline to strike the south of the island as well, with the largest waves generally arriving somewhat after the first ones at each location.

The disaster killed more than 30,000 people in Sri Lanka, the second highest national death toll after Indonesia, and left hundreds of thousands homeless. Among the many small, precise details later gathered by researchers documenting the disaster's exact timing, a public clock on the western coast at Colombo was reported to have stopped at 9:20 that morning, frozen at the moment the water struck it, implying a total travel time for the tsunami of roughly two hours and twenty minutes from the earthquake's origin to the capital.

Arthur C. Clarke and the Orbit Named After Him

In October 1945, a young British radar specialist and science fiction writer named Arthur C. Clarke published a technical paper proposing that satellites placed in a specific orbit, one matching Earth's own rotation so that a satellite would appear to hang motionless above a fixed point on the equator, could serve as relay stations for global radio and television communication. Decades before any such satellite actually flew, Clarke had worked out the essential physics of what would come to be called the geostationary orbit.

In 1956 Clarke moved permanently to Ceylon, later Sri Lanka, drawn largely by his passion for scuba diving in its coastal waters, and he remained there until his death in Colombo in 2008. Sri Lanka granted him citizenship and later its highest civilian honor, and he continued writing prolifically from the island, including the novel that became the film 2001: A Space Odyssey. In recognition of his early technical insight, the International Astronomical Union came to informally call the geostationary orbit, roughly 36,000 kilometers above the equator and now filled with communications and weather satellites that quietly help synchronize time and data around the planet, the Clarke Orbit.

When the Sun Decides the New Year

Unlike the instantaneous midnight switch of the Gregorian new year, the Sinhala and Tamil New Year celebrated across Sri Lanka each April begins at a moment determined by astronomy rather than the clock, specifically the sun's transition from the astrological house of Pisces into the house of Aries. Because that solar crossing takes time rather than happening in an instant, Sri Lankan tradition marks out a distinct nonagathe, or neutral period, lasting roughly twelve to thirteen hours, spanning the gap between the symbolic end of the old year and the start of the new one.

During this neutral interval, ordinary work and business activity are traditionally set aside in favor of religious observance, and astrologers publish detailed almanacs specifying the exact, often minute precise, auspicious times for actions such as lighting the hearth, preparing the first meal, or beginning financial transactions once the new year has formally dawned. The celebration, coinciding with the close of the island's main rice harvest, is observed jointly by both the Buddhist Sinhalese and Hindu Tamil communities, each with its own particular customs layered onto the shared astronomical foundation of the holiday.
