When it is 09:00 in Hong Kong it is 02:00 in Lagos in January and 02:00 in July. Lagos is 7 hours behind Hong Kong 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 Hong Kong and Lagos
The two cities side by side. The January column uses the winter offsets (Hong Kong UTC+08:00, Lagos UTC+01:00); the July column uses the summer offsets (Hong Kong UTC+08:00, Lagos UTC+01:00).

The world clock shows the current time in both cities live, and the individual city pages — time in Hong Kong and time in Lagos — explain each city's time zone, offsets and daylight saving in full.
The time difference between Hong Kong and Lagos
The difference is constant: Lagos is 7 hours behind Hong Kong 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 Hong Kong is always 02:00 in Lagos. The reason the difference never changes is that neither city observes daylight saving.
To convert a time, add the difference: 09:00 in Hong Kong is 02:00 in Lagos in January and 02:00 in July; 17:00 in Hong Kong — the end of the working day — is 10:00 in Lagos in January and 10:00 in July. To go the other way, subtract it: 09:00 in Lagos is 16:00 in Hong Kong in January. The time difference calculator does the arithmetic for any date, and the UTC to Lagos page gives the full conversion table for Lagos.
Meeting overlap between Hong Kong and Lagos
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 Hong Kong's working day and shows what time they are in Lagos.
January
| Hong Kong time | Lagos time | Both working? |
|---|---|---|
| 09:00 | 02:00 | No |
| 10:00 | 03:00 | No |
| 11:00 | 04:00 | No |
| 12:00 | 05:00 | No |
| 13:00 | 06:00 | No |
| 14:00 | 07:00 | No |
| 15:00 | 08:00 | No |
| 16:00 | 09:00 | No |
In January the overlap is 0 hours: there is no hour when both cities are in their working day. In July it is 0 hours: there is no hour when both cities are in their working day. The two working days do not overlap at all — the difference is too large. The only options are to meet at the edge of the day, to rotate the awkward hour, or to record the meeting.
Daylight saving in Hong Kong and Lagos
Hong Kong does not observe daylight saving, so its offset of UTC+08:00 never changes.
Lagos does not observe daylight saving, so its offset of UTC+01:00 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 Hong Kong and London, for example, may still move when London changes its clocks. The individual DST pages — Hong Kong DST 2026 and Lagos DST 2026 — give the exact dates for each city.
Best meeting windows
There is no window inside both working days, in January or in July. The least-bad options are the edges: 08:00 in Hong Kong is 01:00 in Lagos in January — before the working day in Hong Kong but a reasonable evening in Lagos — and 17:00 in Hong Kong is 10:00 in Lagos, which is the morning in Lagos the next day if the difference is large. Rotate the early start between the two sides, week by week, so the same people are not always the ones getting up early.
Calling and travel notes
When it is 09:00 in Hong Kong it is 02:00 in Lagos in January; when it is 12:00 in Hong Kong it is 05:00 in Lagos; when it is 17:00 in Hong Kong it is 10:00 in Lagos. 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 Hong Kong and time in Lagos — explain each city's time zone, and the DST pages — Hong Kong DST 2026 and Lagos DST 2026 — give the exact change dates.
Frequently asked questions
What is the time difference between Hong Kong and Lagos?
Lagos is 7 hours behind Hong Kong right now. In January the difference is 7 hours behind and in July it is 7 hours behind — it is the same all year.
How do I schedule a recurring meeting between Hong Kong and Lagos?
Pick a time inside the overlap — the edge of the day, since there is no overlap — and set the calendar event in UTC so it moves correctly when the clocks change. Re-check the overlap in March and October, when the difference moves, and rotate the time if the meeting falls outside someone's working day.
What time is it in Lagos when it is 09:00 in Hong Kong?
It is 02:00 in January and 02:00 in July. The time zone converter gives the answer for any date.
What is the best time for a meeting between Hong Kong and Lagos?
There is no hour inside both working days. Meet at the edge of the day — early morning in one city, evening in the other — and rotate the awkward hour.
Does the time difference between Hong Kong and Lagos change during the year?
No. The difference is 7 hours behind all year, because neither city observes daylight saving.
What time is it in Hong Kong when it is 09:00 in Lagos?
