Daylight saving
Singapore does not observe daylight saving — this offset is fixed all year. Tokyo does not observe daylight saving — this offset is fixed all year.
A genuinely fixed offset
Neither city observes daylight saving, so the difference between them is the same on every day of the year. This is the easy case: a recurring meeting booked once will remain correct indefinitely, and no seasonal adjustment is ever required.
Scheduling across this corridor
East and Southeast Asia are within an hour or two of each other and neither observes daylight saving, which makes this the most straightforward long-distance corridor on this site. The working days line up almost exactly, the overlap covers the full business day, and the relationship never changes with the season. Scheduling here is effectively a domestic problem.
About Singapore
Singapore holds a fixed offset year-round with no daylight saving, eight hours ahead of UTC — a notable detail given its longitude, since the country sits further east on the clock than the sun would suggest. Its position makes it the standard meeting point for Asian regional business, with a working day that reaches both the European morning and the Australian afternoon.
About Tokyo
Tokyo holds a fixed offset year-round, nine hours ahead of UTC. Japan experimented with daylight saving under the postwar occupation and abandoned it in 1952, and has not observed it since, so the offset is genuinely permanent. Japanese business scheduling tends to be precise about start times, and the working day runs long.
