Live coverage workflow
Use 14:30 to 21:00 UTC as the shared UTC coverage block, then translate it as 09:30 AM to 04:00 PM EST for Nasdaq and 09:30 AM to 04:00 PM EST for NYSE.
Market overlap
Nasdaq vs NYSE overlap
Compare the next common trading window between Nasdaq Stock Market 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.

Nasdaq and NYSE share about 6h 30m of regular-session overlap on the next common trading day, which is the cleanest window for live cross-market monitoring.
Workflow examples
Practical ways to use the Nasdaq / NYSE 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 Nasdaq: Thanksgiving Day (Thu, Nov 26, 2026) Then check NYSE: 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: Nasdaq: Day after Thanksgiving (Fri, Nov 27, 2026, early close 1:00 PM) NYSE: Day after Thanksgiving (Fri, Nov 27, 2026, early close 1:00 PM)
Overlap pair read
Nasdaq and NYSE: 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
Nasdaq vs NYSE is a same country · same currency · deep overlap comparison. Nasdaq and NYSE share the same IANA timezone (America/New_York), so the key difference is venue/session policy rather than clock conversion.
Overlap strength
6h 30m of shared regular-session time equals 100% of the shorter modeled regular-session day. UTC window: 14:30 to 21:00 UTC.
Local-market reading
Nasdaq sees the overlap as 09:30 AM to 04:00 PM EST; NYSE sees it as 09:30 AM to 04:00 PM EST. This is the important distinction from a generic “markets open now” list.
Session denominator
Nasdaq models 390 regular-session minutes per trading day; NYSE 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 Nasdaq market schedule and NYSE hours and calendars. 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
Nasdaq is denominated in USD; NYSE 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
Nasdaq and NYSE: 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
Nasdaq and NYSE share America/New_York today (UTC-05:00). DST drift is unlikely inside the pair, but exchange-specific closures can still break a normal day.
Next full-closure check
Nasdaq: Thanksgiving Day (Thu, Nov 26, 2026) NYSE: 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
Nasdaq: Day after Thanksgiving (Fri, Nov 27, 2026, early close 1:00 PM) NYSE: 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
deep overlap: The shared window is 6h 30m, so it can support a longer cross-market monitoring block after both calendars are confirmed.
Session shape
Both markets are modeled as one continuous regular session per trading day, which makes the overlap block easier to interpret. The pair is within United States, so holiday rules can still differ by venue even when the country is shared.
Currency boundary
Both pages use USD; currency is not the distinguishing factor for this overlap page. 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.
Official sources: Nasdaq market schedule and NYSE hours and calendars. Check both exchanges before making time-sensitive trading decisions.
