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

|---|---|---|
| TSE | 09:00 | 15:30 |
| SGX | 09:00 | 17:00 |
How the TSE–SGX overlap is calculated
The overlap is the intersection of each exchange’s regular trading session after converting both to London Time. In this timezone, TSE runs 09:00–15:30 and SGX runs 09:00–17:00, so both are open together from 01:00 to 06:30 — 5h 30m 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.
