When it is 09:00 in Nairobi it is 15:00 in Tokyo in January and 15:00 in July. Tokyo is 6 hours ahead Nairobi right now — and the difference is the same all year. This page gives the live times in both cities, the overlap between their working days, the daylight saving dates that move the difference, and the best meeting windows.

Live times in Nairobi and Tokyo
The two cities side by side. The January column uses the winter offsets (Nairobi UTC+03:00, Tokyo UTC+09:00); the July column uses the summer offsets (Nairobi UTC+03:00, Tokyo UTC+09:00).

The world clock shows the current time in both cities live, and the individual city pages — time in Nairobi and time in Tokyo — explain each city's time zone, offsets and daylight saving in full.
The time difference between Nairobi and Tokyo
The difference is constant: Tokyo is 6 hours ahead Nairobi on every day of the year. That is the simplest case in time-zone work — the answer does not depend on the date, and a meeting set for 09:00 in Nairobi is always 15:00 in Tokyo. The reason the difference never changes is that neither city observes daylight saving.
To convert a time, add the difference: 09:00 in Nairobi is 15:00 in Tokyo in January and 15:00 in July; 17:00 in Nairobi — the end of the working day — is 23:00 in Tokyo in January and 23:00 in July. To go the other way, subtract it: 09:00 in Tokyo is 03:00 in Nairobi in January. The time difference calculator does the arithmetic for any date, and the UTC to Tokyo page gives the full conversion table for Tokyo.
Meeting overlap between Nairobi and Tokyo
The overlap is the hours when both cities are in their working day (09:00–17:00 local time). The table marks the overlapping hours in Nairobi's working day and shows what time they are in Tokyo.
January
| Nairobi time | Tokyo time | Both working? |
|---|---|---|
| 09:00 | 15:00 | Yes |
| 10:00 | 16:00 | Yes |
| 11:00 | 17:00 | Yes |
| 12:00 | 18:00 | Yes |
| 13:00 | 19:00 | Yes |
| 14:00 | 20:00 | Yes |
| 15:00 | 21:00 | Yes |
| 16:00 | 22:00 | Yes |
In January the overlap is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 Nairobi time. In July it is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 Nairobi time. The meeting planner finds the overlap for any two cities and any date, and the meeting time finder finds it for a whole team.
Daylight saving in Nairobi and Tokyo
Nairobi does not observe daylight saving, so its offset of UTC+03:00 never changes.
Tokyo does not observe daylight saving, so its offset of UTC+09:00 never changes.
The difference never changes, so there is no date on which a standing meeting moves. That does not mean the difference is the same as the difference with a third city — the difference between Nairobi and London, for example, may still move when London changes its clocks. The individual DST pages — Nairobi DST 2026 and Tokyo DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 09:00–17:00 in Nairobi (15:00–23:00 in Tokyo). These are the hours inside both working days, so nobody is up early or late. It is a short window, so keep the meeting short and send an agenda in advance.
Calling and travel notes
When it is 09:00 in Nairobi it is 15:00 in Tokyo in January; when it is 12:00 in Nairobi it is 18:00 in Tokyo; when it is 17:00 in Nairobi it is 23:00 in Tokyo. The difference is under 12 hours, so the two cities are usually on the same date — but check the date for late-evening and early-morning times, when the date can differ by a day. Scheduling between Africa and Asia means a difference of 2–6 hours, so the working days overlap for most of the day. Neither side usually observes daylight saving — most African and Asian countries do not — so the difference is constant all year, which makes recurring meetings easy to keep.

The table is the whole pair in one place. The two numbers that matter most are the January and July offsets: if they are the same in both columns for a city, that city's offset never changes; if they differ, the city observes daylight saving and the difference between the cities moves with it. The individual city pages — time in Nairobi and time in Tokyo — explain each city's time zone, and the DST pages — Nairobi DST 2026 and Tokyo DST 2026 — give the exact change dates.
