Hong Kong TimeTimes assume the exchanges’ regular sessions and are converted from exchange local time to Hong Kong Time; holidays and early closes can remove the overlap on a given day.

| TSE | 17:00 | 23:30 |
| HKEX | 17:30 | 00:00 |
How the TSE–HKEX overlap is calculated
The overlap is the intersection of each exchange’s regular trading session after converting both to Hong Kong Time. In this timezone, TSE runs 17:00–23:30 and HKEX runs 17:30–00:00, so both are open together from 09:30 to 14:30 — 5h of shared trading time.
Weekends are excluded, and any full-day holiday or early close on either side shrinks the window for that date. Use the two holiday calendars below before planning a session that relies on the overlap, and check the live open/closed status if you need the current figure rather than the scheduled one.
