When it is 09:00 in Seoul it is 02:00 in Cairo in January and 03:00 in July. Cairo is 7 hours behind Seoul right now — but it is not constant: the difference is 7 hours behind in January and 6 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 Seoul and Cairo
The two cities side by side. The January column uses the winter offsets (Seoul UTC+09:00, Cairo UTC+02:00); the July column uses the summer offsets (Seoul UTC+09:00, Cairo UTC+03:00).

The world clock shows the current time in both cities live, and the individual city pages — time in Seoul and time in Cairo — explain each city's time zone, offsets and daylight saving in full.
The time difference between Seoul and Cairo
The difference is not constant. In January Cairo is 7 hours behind Seoul; in July it is 6 hours behind Seoul. The difference changes on Friday, 24 April 2026 (from 7 hours behind to 6 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 Seoul is 02:00 in Cairo in January and 03:00 in July; 17:00 in Seoul — the end of the working day — is 10:00 in Cairo in January and 11:00 in July. To go the other way, subtract it: 09:00 in Cairo is 16:00 in Seoul 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 Seoul 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 Seoul's working day and shows what time they are in Cairo.
January
| Seoul time | Cairo 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 |
July
| Seoul 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 |
In January the overlap is 0 hours: there is no hour when both cities are in their working day. In July it is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 Seoul 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 Seoul and Cairo
Seoul does not observe daylight saving, so its offset of UTC+09:00 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 — Seoul DST 2026 and Cairo DST 2026 — give the exact dates for each city.
Best meeting windows
In July the best windows are 09:00–17:00 in Seoul (03:00–11:00 in Cairo) — the same logic, with the July offsets.
Calling and travel notes
When it is 09:00 in Seoul it is 02:00 in Cairo in January; when it is 12:00 in Seoul it is 05:00 in Cairo; when it is 17:00 in Seoul it is 10:00 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.
Worked conversions

In July, add 1 hour to each Cairo time. For the reverse direction, see Cairo to Seoul time.

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 Seoul and time in Cairo — explain each city's time zone, and the DST pages — Seoul DST 2026 and Cairo DST 2026 — give the exact change dates.
Frequently asked questions
What is the time difference between Seoul and Cairo?
Cairo is 7 hours behind Seoul right now. In January the difference is 7 hours behind and in July it is 6 hours behind — it changes with daylight saving.
How do I schedule a recurring meeting between Seoul and Cairo?
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 Cairo when it is 09:00 in Seoul?
It is 02:00 in January and 03:00 in July. The time zone converter gives the answer for any date.
What is the best time for a meeting between Seoul and Cairo?
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 Seoul and Cairo change during the year?
Yes. It changes on Friday, 24 April 2026 in 2026, when one city changes its clocks and the other does not.

It is 16:00 in January and 15:00 in July. See Cairo to Seoul time for the full comparison from Cairo's side.
What are the time zones of Seoul and Cairo?
Seoul is in Asia/Seoul (UTC+09:00 standard time) and Cairo is in Africa/Cairo (UTC+02:00 standard time).
What time is it in Seoul when it is midnight in Cairo?
It is 07:00 in Seoul in January and 06:00 in July — the previous day, because Cairo is ahead of Seoul. Midnight conversions are the ones that most often land on the wrong date, so always check the date as well as the time.
