Does the difference between Singapore and Tokyo change during the year?

No. The difference is 1 hour for the whole of 2026: neither city observes daylight saving time.

Best time to call Tokyo from Singapore (and vice versa)

The window in which both cities are inside their 9:00–17:00 working day runs from 09:00 to 16:00 in Singapore, which is 10:00 to 17:00 in Tokyo: 7 hours of overlap per day. For a call that disturbs nobody, aim for the middle of that window.

Outside that window, the practical rule: mornings in Tokyo are afternoons in Singapore. Avoid any hour that falls before 8:00 or after 21:00 in either city.
