How the HKEX–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, HKEX runs 20:30–03:00 and SGX runs 20:00–04:00, so both are open together from 12:30 to 19:00 — 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.
