When it is 09:00 in Cairo it is 15:00 in Hong Kong in January and 14:00 in July. Hong Kong is 6 hours ahead Cairo right now — but it is not constant: the difference is 6 hours ahead in January and 5 hours ahead 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 Cairo and Hong Kong
The two cities side by side. The January column uses the winter offsets (Cairo UTC+02:00, Hong Kong UTC+08:00); the July column uses the summer offsets (Cairo UTC+03:00, Hong Kong UTC+08:00).

The world clock shows the current time in both cities live, and the individual city pages — time in Cairo and time in Hong Kong — explain each city's time zone, offsets and daylight saving in full.
The time difference between Cairo and Hong Kong
The difference is not constant. In January Hong Kong is 6 hours ahead Cairo; in July it is 5 hours ahead Cairo. The difference changes on Friday, 24 April 2026 (from 6 hours ahead to 5 hours ahead) — 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 Cairo is 15:00 in Hong Kong in January and 14:00 in July; 17:00 in Cairo — the end of the working day — is 23:00 in Hong Kong in January and 22:00 in July. To go the other way, subtract it: 09:00 in Hong Kong is 03:00 in Cairo in January. The time difference calculator does the arithmetic for any date, and the UTC to Hong Kong page gives the full conversion table for Hong Kong.
Meeting overlap between Cairo and Hong Kong
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 Cairo's working day and shows what time they are in Hong Kong.
January
| Cairo time | Hong Kong 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 |

July
| Cairo time | Hong Kong time | Both working? |
|---|---|---|
| 09:00 | 14:00 | No |
| 10:00 | 15:00 | No |
| 11:00 | 16:00 | No |
| 12:00 | 17:00 | No |

| 14:00 | 19:00 | No |
| 15:00 | 20:00 | No |
| 16:00 | 21:00 | No |
In January the overlap is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 Cairo 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 Cairo and Hong Kong
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.
Hong Kong does not observe daylight saving, so its offset of UTC+08:00 never changes.
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 — Cairo DST 2026 and Hong Kong DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 09:00–17:00 in Cairo (15:00–23:00 in Hong Kong). 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 Cairo it is 15:00 in Hong Kong in January; when it is 12:00 in Cairo it is 18:00 in Hong Kong; when it is 17:00 in Cairo it is 23:00 in Hong Kong. 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 Cairo and time in Hong Kong — explain each city's time zone, and the DST pages — Cairo DST 2026 and Hong Kong DST 2026 — give the exact change dates.
