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

How the SSE–HKEX overlap is calculated
The overlap is the intersection of each exchange’s regular trading session after converting both to India Standard Time. In this timezone, SSE runs 15:00–20:30 and HKEX runs 15:00–21:30, so both are open together from 07:00 to 12:30 — 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.
