Tokyo uses Japan Standard Time (JST, UTC+9) year-round. Japan does not observe Daylight Saving Time — the country trialled it briefly after WWII but abandoned it. The fixed JST offset makes Japan scheduling particularly straightforward despite the large distance from Europe and the Americas.
Sydney uses Australian Eastern Standard Time (AEST, UTC+10) in winter and Australian Eastern Daylight Time (AEDT, UTC+11) in summer. Because Australia is in the Southern Hemisphere, its summer runs October–April — the opposite of the Northern Hemisphere. Clocks go forward on the first Sunday of October and back on the first Sunday of April.
Both Tokyo and Sydney may observe Daylight Saving Time, which means the offset between them can change twice a year. Here is what to expect each season.
| Period | Note | Tokyo | Sydney | Offset |
|---|---|---|---|---|
| Nov – Mar | Both on standard time | GMT+9 (UTC+9) | GMT+11 (UTC+11) | 2 hours |
| Mar – late Mar | US clocks forward, some zones still on standard | GMT+9 (UTC+9) | GMT+11 (UTC+11) | 2 hours |
| Late Mar – Oct current | Both on summer / daylight time | GMT+9 (UTC+9) | GMT+10 (UTC+10) | 1 hour |
| Late Oct – early Nov | Clocks transitioning — check exact date | GMT+9 (UTC+9) | GMT+11 (UTC+11) | 2 hours |
The transition window typically lasts 1–2 weeks in spring and autumn. If you have a recurring weekly meeting near a clock change, verify the exact date to avoid a missed call.
