When it is 09:00 in Paris it is 17:00 in Seoul in January and 16:00 in July. Seoul is 8 hours ahead Paris right now — but it is not constant: the difference is 8 hours ahead in January and 7 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 Paris and Seoul
The two cities side by side. The January column uses the winter offsets (Paris UTC+01:00, Seoul UTC+09:00); the July column uses the summer offsets (Paris UTC+02:00, Seoul UTC+09:00).

The world clock shows the current time in both cities live, and the individual city pages — time in Paris and time in Seoul — explain each city's time zone, offsets and daylight saving in full.
The time difference between Paris and Seoul
The difference is not constant. In January Seoul is 8 hours ahead Paris; in July it is 7 hours ahead Paris. The difference changes on Sunday, 29 March 2026 (from 8 hours ahead to 7 hours ahead) and Sunday, 25 October 2026 (from 7 hours ahead to 8 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 Paris is 17:00 in Seoul in January and 16:00 in July; 17:00 in Paris — the end of the working day — is 01:00 in Seoul in January and 00:00 in July. To go the other way, subtract it: 09:00 in Seoul is 01:00 in Paris in January. The time difference calculator does the arithmetic for any date, and the UTC to Seoul page gives the full conversion table for Seoul.
Meeting overlap between Paris and Seoul
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 Paris's working day and shows what time they are in Seoul.
January
| Paris time | Seoul time | Both working? |
|---|---|---|
| 09:00 | 17:00 | Yes |
| 10:00 | 18:00 | Yes |
| 11:00 | 19:00 | Yes |
| 12:00 | 20:00 | Yes |
| 13:00 | 21:00 | Yes |

| 15:00 | 23:00 | Yes |
| 16:00 | 00:00 | Yes |
July
| Paris time | Seoul time | Both working? |
|---|---|---|
| 09:00 | 16:00 | No |
| 10:00 | 17:00 | No |
| 11:00 | 18:00 | No |
| 12:00 | 19:00 | No |
| 13:00 | 20:00 | No |
| 14:00 | 21:00 | No |
| 15:00 | 22:00 | No |
| 16:00 | 23:00 | No |
In January the overlap is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 Paris 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 Paris and Seoul
Paris observes daylight saving: in 2026 the clocks go forward on 29 March 2026 and back on 25 October 2026, moving the offset from UTC+01:00 to UTC+02:00.
Seoul does not observe daylight saving, so its offset of UTC+09:00 never changes.
The difference changes on Sunday, 29 March 2026 and Sunday, 25 October 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 — Paris DST 2026 and Seoul DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 09:00–17:00 in Paris (17:00–01:00 in Seoul). 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 Paris it is 17:00 in Seoul in January; when it is 12:00 in Paris it is 20:00 in Seoul; when it is 17:00 in Paris it is 01:00 in Seoul. 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 Asia and Europe works best in the late morning in Seoul and the afternoon or evening in Paris. The difference is 5–9 hours, so the overlap is a few hours in the middle of the day. The main trap is daylight saving: Europe changes its clocks twice a year, and most of Asia does not, so the difference — and the overlap — moves by an hour in March and October.

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 Paris and time in Seoul — explain each city's time zone, and the DST pages — Paris DST 2026 and Seoul DST 2026 — give the exact change dates.
