Live coverage workflow
There is no same-day live overlap, so treat the pair as a sequential handoff: finish the HKEX watch, then pass context before NYSE becomes active.

Market overlap
Compare the next common trading window between Hong Kong Exchanges and Clearing and New York Stock Exchange, 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.

HKEX and NYSE do not share a live regular-session window on the next common trading day, so teams usually rely on hand-offs rather than simultaneous cash-market trading.

Workflow examples
The overlap page is for calendar and operations planning. It should help teams schedule monitoring, handoffs, and source checks without drifting into investment advice.
There is no same-day live overlap, so treat the pair as a sequential handoff: finish the HKEX watch, then pass context before NYSE becomes active.
Before scheduling a recurring cross-market ritual, check HKEX: Hong Kong Special Administrative Region Establishment Day (Wed, Jul 1, 2026) Then check NYSE: Juneteenth National Independence Day (Fri, Jun 19, 2026)
If the overlap matters for publishing, ops, or compliance timing, check half-day sensitivity first: HKEX: Christmas Eve (Thu, Dec 24, 2026, early close 12:00 PM) NYSE: Day before Independence Day (Thu, Jul 2, 2026, early close 1:00 PM)

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.
Official sources: HKEX securities-market trading hours and NYSE hours and calendars. Check both exchanges before making time-sensitive trading decisions.
