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

How the HKEX–SGX overlap is calculated
The overlap is the intersection of each exchange’s regular trading session after converting both to Singapore Time. In this timezone, HKEX runs 17:30–00:00 and SGX runs 17:00–01:00, so both are open together from 09:30 to 16:00 — 6h 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.
