When it is 09:00 in Hong Kong it is 03:00 in Cairo in January and 04:00 in July. Cairo is 6 hours behind Hong Kong right now — but it is not constant: the difference is 6 hours behind in January and 5 hours behind in July. 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 Cairo
The two cities side by side. The January column uses the winter offsets (Hong Kong UTC+08:00, Cairo UTC+02:00); the July column uses the summer offsets (Hong Kong UTC+08:00, Cairo UTC+03:00).

The world clock shows the current time in both cities live, and the individual city pages — time in Hong Kong and time in Cairo — explain each city's time zone, offsets and daylight saving in full.
The time difference between Hong Kong and Cairo
The difference is not constant. In January Cairo is 6 hours behind Hong Kong; in July it is 5 hours behind Hong Kong. The difference changes on Friday, 24 April 2026 (from 6 hours behind to 5 hours behind) — those are the dates when one of the two cities changes its clocks and the other does not, or when they change on different days. Between those dates the difference is one value; outside them it is the other.
To convert a time, add the difference: 09:00 in Hong Kong is 03:00 in Cairo in January and 04:00 in July; 17:00 in Hong Kong — the end of the working day — is 11:00 in Cairo in January and 12:00 in July. To go the other way, subtract it: 09:00 in Cairo is 15:00 in Hong Kong in January. The time difference calculator does the arithmetic for any date, and the UTC to Cairo page gives the full conversion table for Cairo.
Meeting overlap between Hong Kong and Cairo
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 Cairo.
January
| Hong Kong time | Cairo time | Both working? |
|---|---|---|
| 09:00 | 03:00 | Yes |
| 10:00 | 04:00 | Yes |
| 11:00 | 05:00 | Yes |
| 12:00 | 06:00 | Yes |
| 13:00 | 07:00 | Yes |
| 14:00 | 08:00 | Yes |
| 15:00 | 09:00 | Yes |
| 16:00 | 10:00 | Yes |
July
| Hong Kong time | Cairo time | Both working? |
|---|---|---|
| 09:00 | 04:00 | No |
| 10:00 | 05:00 | No |
| 11:00 | 06:00 | No |
| 12:00 | 07:00 | No |
| 13:00 | 08:00 | No |
| 14:00 | 09:00 | No |
| 15:00 | 10:00 | No |
| 16:00 | 11:00 | No |
In January the overlap is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 Hong Kong time. In July it is 0 hours: there is no hour when both cities are in their working day. 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 Hong Kong and Cairo
Hong Kong does not observe daylight saving, so its offset of UTC+08:00 never changes.
Cairo observes daylight saving: in 2026 the clocks go forward on 24 April 2026 and back on 29 October 2026, moving the offset from UTC+02:00 to UTC+03:00.
The difference changes on Friday, 24 April 2026 in 2026. On those dates, one city changes its clocks and the other does not — or they change on different days — so the difference moves by an hour. A standing meeting set in one city's local time will land an hour early or late on the other side until the second city catches up. The fix is to set the calendar event in UTC, or to check the overlap again after each change. The individual DST pages — Hong Kong DST 2026 and Cairo DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 09:00–17:00 in Hong Kong (03:00–11:00 in Cairo). 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 Hong Kong it is 03:00 in Cairo in January; when it is 12:00 in Hong Kong it is 06:00 in Cairo; when it is 17:00 in Hong Kong it is 11:00 in Cairo. 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 Cairo — explain each city's time zone, and the DST pages — Hong Kong DST 2026 and Cairo DST 2026 — give the exact change dates.
