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 Nasdaq becomes active.
Market overlap
HKEX vs Nasdaq overlap
Compare the next common trading window between Hong Kong Exchanges and Clearing and Nasdaq Stock Market, 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.
Live values rendered at Nov 5, 7:05 PM UTC.

HKEX and Nasdaq 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
Practical ways to use the HKEX / Nasdaq overlap
The overlap page is for calendar and operations planning. It should help teams schedule monitoring, handoffs, and source checks without drifting into investment advice.
Closure pre-check workflow
Before scheduling a recurring cross-market ritual, check HKEX: Christmas Day (Fri, Dec 25, 2026) Then check Nasdaq: Thanksgiving Day (Thu, Nov 26, 2026)
Half-day and notice workflow
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) Nasdaq: Day after Thanksgiving (Fri, Nov 27, 2026, early close 1:00 PM)
Overlap pair read
HKEX and Nasdaq: why this pair is different
The same overlap length can hide important differences. This read exposes the pair-specific clock relationship, session denominator, source boundary, currency split, and whether the common window is deep enough to be useful.
Pair fingerprint
HKEX vs Nasdaq is a cross-country · different currencies · no live overlap comparison. HKEX uses Asia/Hong_Kong; Nasdaq uses America/New_York. The overlap has to be read through two exchange-local clocks, not a fixed UTC offset.
Overlap strength
There is no shared regular-session minute in the next common window, so this pair is better treated as a monitoring handoff. UTC window: No overlap.
Local-market reading
HKEX sees the overlap as Morning session: 9:30 AM-12:00 PM · Afternoon session: 1:00 PM-4:00 PM; Nasdaq sees it as Regular session: 9:30 AM-4:00 PM. This is the important distinction from a generic “markets open now” list.
Session denominator
HKEX models 330 regular-session minutes per trading day; Nasdaq models 390. The overlap percentage is based on the shorter of those two regular-session totals.
Source boundary
Regular sessions and full-day closures come from HKEX securities-market trading hours and Nasdaq market schedule. The page does not model half-days, auctions, lunch-break changes beyond the stored sessions, halts, circuit breakers, or emergency exchange notices.
Currency and venue context
HKEX is denominated in HKD; Nasdaq is denominated in USD. This page helps with schedule overlap, not relative value, liquidity, or trade recommendations.
A strong schedule overlap is still not a trading recommendation. It only means the modeled regular sessions share minutes after timezone conversion and tracked full-day closures are skipped.
Calendar watchlist
HKEX and Nasdaq: closures, half-days, and DST checks
A pair can look similar to another pair if you only compare the overlap minutes. The practical reading depends on whether the exchanges share a timezone, whether one side has an upcoming closure or half-day, and how much of the shared window survives after both regular-session calendars are applied.
Timezone drift watch
HKEX is UTC+08:00 in Asia/Hong_Kong; Nasdaq is UTC-05:00 in America/New_York. Recheck the page around DST transition weeks because one side can move while the other does not.
Next full-closure check
HKEX: Christmas Day (Fri, Dec 25, 2026) Nasdaq: Thanksgiving Day (Thu, Nov 26, 2026) The overlap skips modeled full-day closures, but unusual exchange notices still belong to the official calendars.
Half-day sensitivity
HKEX: Christmas Eve (Thu, Dec 24, 2026, early close 12:00 PM) Nasdaq: Day after Thanksgiving (Fri, Nov 27, 2026, early close 1:00 PM) Half-days can shorten or remove the practical overlap even when the regular-session model says both markets are open.
Coordination pattern
no live overlap: Use this as a handoff page: one market is usually monitored before or after the other, not during a shared live block.
Session shape
HKEX has a split regular session, so the overlap grid should be read as separate open blocks rather than one continuous day. HKEX is anchored in Hong Kong; Nasdaq is anchored in United States. Cross-country pairs need both calendars checked.
Currency boundary
HKEX is denominated in HKD, while Nasdaq is denominated in USD; schedule overlap does not imply currency or liquidity equivalence. This page is a calendar and timezone reference only, not a trading signal or investment comparison.
Use the watchlist as a pre-check before relying on the overlap for publishing, operations, settlement planning, or live market monitoring. It still does not replace the official exchange notice feeds.

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.
