Current Time in Singapore

Singapore time, through three flags

Singapore's clock has moved more times than almost any other major city's, tracking who governed the island rather than where the sun sat. Until 1905 the Straits Settlements kept local mean time based on Singapore's own meridian; that year the colonial government adopted a standardised time zone, chosen to ease railway and postal coordination across British Malaya. To mark the change to the public, a cannon on Fort Canning Hill was fired every day at noon starting in 1905, giving merchants and residents across the port a shared signal to check their watches by — a practice that continued for several years before more reliable telegraph time signals made it unnecessary.

The clock moved again in 1933, shifting to Malaya Time at UTC+7:30. Then, during the Japanese Occupation from 1942 to 1945, Singapore's clocks were forced forward to Tokyo Time, UTC+9, overnight — a jump of more than an hour imposed purely to align the occupied territory with Japan's own schedule. After the war, Singapore reverted to UTC+7:30, and it wasn't until 1982, in independent Singapore, that the government made the final jump to today's fixed UTC+8, explicitly to align business hours with Hong Kong and other regional trading partners rather than for any solar reason.

Planning around Singapore's real calendar

A few Singapore-specific scheduling details are worth knowing beyond the standard office day:

• Chinese New Year (dates vary each year on the lunar calendar) is the single biggest disruption to the business calendar, with many offices closing for two official public holidays plus a half-day for the reunion dinner eve.
• Hari Raya Puasa and Deepavali, marking the end of Ramadan and the Hindu festival of lights respectively, are both public holidays that shift business scheduling for Singapore's Malay-Muslim and Indian communities each year.
• The Singapore Grand Prix, held most years in September, is one of the only Formula 1 night races, deliberately timed to start at dusk so the live broadcast lands in a convenient evening slot for European viewers.
• The Port of Singapore, the world's busiest transshipment hub, runs its PSA terminals 24/7, so shipping and logistics correspondence isn't bound to the 9:00–18:00 office day the way most other business communication is.

A clock shifted for trade, not the sun

Singapore's geography would place it naturally near UTC+7, which is roughly what its longitude implies and what it briefly used in the early 1980s. In 1982, the government shifted the clock forward by 30 minutes to UTC+8, deliberately aligning Singapore Standard Time with Hong Kong, Beijing, and other major regional financial centers. The move was explicitly about smoothing business hours with trading partners rather than tracking the sun, and it's stayed at UTC+8 ever since.

A one-time-zone club with several major members

Because of that 1982 shift, Singapore now shares an identical fixed offset with several major cities that would otherwise sit in slightly different zones: Hong Kong, Shanghai, Manila, and Perth, Australia (which also observes no daylight saving) all read the same clock as Singapore, year-round, with zero conversion required between any of them.

Time differences from Singapore

Because Singapore never changes its own clock, every gap below moves only when the other city shifts for its own daylight saving.

Shanghai and Tokyo are the simplest comparisons, and Shanghai in particular is always exactly identical — no conversion needed at all.

Working hours and when to call

Most Singapore offices run roughly 9:00 to 18:00, Monday to Friday, and the Singapore Exchange trades 9:00 to 17:00 SGT.

• From East Asia: near-total overlap with Shanghai and close overlap with Tokyo, given the one-hour or zero gap.
• From Europe: a Singapore afternoon overlaps a London or Paris morning.
• From the US East Coast: minimal overlap; a Singapore morning call lands very late the previous night in New York.
• From Sydney: a comfortable overlap through much of the working day, given the small 2–3 hour gap.

Chinese New Year (dates vary each year on the lunar calendar) is the single biggest disruption to Singapore's business calendar, often pausing activity for several days.

Daylight through the year

At just 1.35°N — essentially on the equator — Singapore has almost no seasonal daylight variation at all. Day length stays close to 12 hours year-round, varying by only a few minutes between the shortest and longest days, unlike higher-latitude cities where the swing can exceed eight hours.

How we calculate this page: the live clock and UTC offset come from the IANA time zone database (Asia/Singapore). Sunrise, sunset, solar noon, twilight, and moon phase are computed from Singapore's coordinates (1.3521°N, 103.8198°E) using standard astronomical formulas, recalculated on every page load. Weather is pulled live from Open-Meteo. The history and scheduling notes above were researched and written specifically for Singapore.
