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

| TSE | 20:00 | 02:30 |
| SGX | 20:00 | 04:00 |
How the TSE–SGX overlap is calculated
The overlap is the intersection of each exchange’s regular trading session after converting both to Australian Eastern Time. In this timezone, TSE runs 20:00–02:30 and SGX runs 20:00–04:00, so both are open together from 12:00 to 17:30 — 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.
