Market overlap
Compare the next common trading window between Hong Kong Exchanges and Clearing and Japan Exchange Group, including local times in both markets and the UTC overlap block.
Schedule reviewed Apr 30, 2026. Overlap windows are recalculated from regular-session catalogs and skip tracked full-day exchange closures. Half-days, halts, auctions, and emergency notices can still override a normal session, so confirm time-sensitive trading decisions with the exchange.

Caveats
The overlap calculation skips tracked full-day closures, but it does not promise that both exchanges are tradable through half-days, auctions, lunch extensions, halts, or emergency notices.
