Time difference between Tokyo and Singapore

The gap holds all year

Neither city changes its clocks — Tokyo does not change its clocks and Singapore does not change its clocks — so 1 hour is the difference in January and in July alike. That is worth knowing about this pair specifically, because most international pairs do move and a recurring meeting between them does not need checking twice a year.

About Tokyo and Singapore

Japan is UTC+9 with no daylight saving anywhere, and has not had it since the occupation ended in 1952. The whole country runs one zone and the business day starts early, so the useful overlap with Europe is Japan's late afternoon.

Singapore is UTC+8 despite sitting almost on the equator at a longitude that suggests UTC+7. It moved forward in 1982 to align with Malaysia and never moved back, so solar noon falls at about 1 PM.

What 1 hour actually costs you

This is an easy pair. 7 hours of the working day are shared, which is enough for a standing meeting at a time neither side has to think about. 10:00 AM–5:00 PM in Tokyo lands inside office hours at both ends.

When they can both be at their desks

Nine-to-five in both cities overlaps for 7 hours — 10:00 AM to 5:00 PM in Tokyo, the same moment as 9:00 AM to 4:00 PM in Singapore.

How far apart Tokyo and Singapore are

The shortest path over the Earth's surface between the two is 5,311 km (3,300 miles). Flown along that line, an airliner at cruising speed takes roughly 6 hours 55 minutes in the air — actual routings add to it, and whether a nonstop service exists depends on the airlines rather than the distance.

A gap of 1 hour is small enough that most people adjust within a day or two, and short enough that it rarely disrupts a trip.
