Korea Exchange trading hours
Korea Exchange trades from 09:00 to 15:30 local time in Seoul, which is 00:00 to 06:30 UTC in winter. Below are the exact sessions, the 2026 holiday calendar, and the hours it shares with the other major exchanges.
Trading hours
Because this zone never shifts its clocks, both columns hold all year. What moves is the gap to the markets that do change their time.
| Session | Local time | UTC (winter) | UTC (summer) |
|---|---|---|---|
| Session | 09:00–15:30 | 00:00–06:30 | 00:00–06:30 |
The exchange trades Monday to Friday. It does not open at weekends.
Time zone and daylight saving
Seoul runs on UTC+9 and does not change its clocks. The local opening time is the same every day of the year, but the distance to markets that do change shifts twice a year: for a few months Seoul is an hour closer to Europe and to North America than it is for the rest.
Which markets are open at the same time
Overlaps are where the volume is. Two exchanges trading at once means more participants pricing the same news, and orders that move the price less. The figures below are calculated from the official hours, not estimated.
| Market | City | Overlap in winter | Overlap in summer |
|---|---|---|---|
| Australian Securities Exchange | Sydney | 5h | 6h |
| Tokyo Stock Exchange | Tokyo | 5h 30min | 5h 30min |
| Hong Kong Exchanges | Hong Kong | 4h | 4h |
| Shanghai Stock Exchange | Shanghai | 3h 30min | 3h 30min |
| National Stock Exchange of India | Mumbai | 2h 45min | 2h 45min |
