what time does the stock market close in arizona

Stock market closing time in Arizona

This page answers the question what time does the stock market close in arizona and explains why that closing clock time changes during the year. You’ll get a clear quick answer, exact conversions for regular and extended sessions, the Navajo Nation daylight‑saving exception, holiday/half‑day impacts, broker considerations, and tips for Arizona-based traders. By the end you can confidently convert U.S. exchange hours (NYSE/Nasdaq) to Arizona local time and plan orders around the close.

Summary (quick answer)

Quick answer: during U.S. Eastern Daylight Time (roughly mid‑March to early November) the regular market close at 4:00 PM Eastern equals 1:00 PM in most of Arizona; during Eastern Standard Time (roughly early November to mid‑March) the regular market close at 4:00 PM Eastern equals 2:00 PM in most of Arizona. Remember Arizona observes Mountain Standard Time year‑round (UTC−7) except for the Navajo Nation, which observes daylight saving time and follows Mountain Daylight Time during DST periods.

U.S. regular market hours and the baseline time (NYSE/Nasdaq)

The official regular session for major U.S. equity exchanges (NYSE and Nasdaq) is 9:30 AM to 4:00 PM Eastern Time. All time conversions in this article are based on that official schedule. As of 2025-12-31, according to exchange hours published by Nasdaq and NYSE, the regular cash market window remains 9:30 AM–4:00 PM Eastern. When converting, use the 4:00 PM Eastern closing time as the baseline point to compute Arizona local time.

Notes on scope: this guide focuses on U.S. equity exchange trading hours (cash session for NYSE/Nasdaq). It does not cover cryptocurrency markets (which trade 24/7) or foreign exchanges. For platform-specific availability of extended hours or special order types, check your broker or trading platform documentation; for Bitget users, see Bitget platform notices in your account.

Arizona time zone rules and daylight saving time

Most of Arizona follows Mountain Standard Time (MST, UTC−7) year‑round and does not change clocks for daylight saving time. That means Arizona stays at UTC−7 while many U.S. regions shift between Eastern Standard Time (EST, UTC−5) and Eastern Daylight Time (EDT, UTC−4). The result: the offset between Eastern Time and Arizona local time changes depending on whether Eastern Time is on DST.

Exception: the Navajo Nation, located in northeastern Arizona, observes daylight saving time and shifts to Mountain Daylight Time (MDT, UTC−6) during the DST period. This creates a local difference between most Arizona communities and those within the Navajo Nation during DST.

Practical consequence: Arizona’s clock does not spring forward or fall back on the state‑wide dates used by most of the U.S., which often creates confusion when converting market open/close times.

Seasonal offsets — how conversion works

• When Eastern Time is on daylight saving time (EDT, UTC−4), Arizona is 3 hours behind Eastern. So 4:00 PM ET = 1:00 PM Arizona (most of state).
• When Eastern Time is on standard time (EST, UTC−5), Arizona is 2 hours behind Eastern. So 4:00 PM ET = 2:00 PM Arizona (most of state).

For the Navajo Nation inside Arizona (which observes DST): during EDT the Navajo Nation is only 2 hours behind Eastern (4:00 PM ET = 2:00 PM Navajo Nation local time); during EST it is 3 hours behind Eastern (4:00 PM ET = 1:00 PM Navajo Nation local time). That flips the usual offset relationship and is a frequent source of confusion for traders and market participants in that region.

Regular-session times mapped to Arizona local time (examples)

Below are straightforward conversions for the official market open and close times. All conversions follow the baseline 9:30 AM–4:00 PM Eastern session.

• Regular market open:
  • 9:30 AM Eastern = 6:30 AM Arizona during EDT (most of AZ)
  • 9:30 AM Eastern = 7:30 AM Arizona during EST (most of AZ)
• Regular market close:
  • 4:00 PM Eastern = 1:00 PM Arizona during EDT (most of AZ)
  • 4:00 PM Eastern = 2:00 PM Arizona during EST (most of AZ)

Examples using the exact search term to reinforce conversions: what time does the stock market close in arizona? During EDT (mid‑March to early November) it closes at 1:00 PM local time, and during EST (early November to mid‑March) it closes at 2:00 PM local time.

Note: the Navajo Nation observes DST; if you are physically located inside the Navajo Nation, confirm local time rules before placing orders.

Extended-hours and pre-market trading (how they map to Arizona)

Many brokers and electronic trading venues offer extended‑hours trading outside the official 9:30 AM–4:00 PM Eastern regular session. Common extended windows (varies by broker/platform):

• Pre‑market: typically begins as early as 4:00 AM Eastern and runs until 9:30 AM Eastern (some brokers open pre‑market at 7:00 AM Eastern or later).
• After‑hours (post‑market): commonly from 4:00 PM Eastern to 8:00 PM Eastern (exact end time depends on the trading venue and broker).

Map these windows to Arizona by subtracting the seasonal offset:

• Pre‑market conversion examples (most of Arizona):
  • If platform pre‑market starts at 4:00 AM ET: that equals 1:00 AM AZ during EDT or 2:00 AM AZ during EST.
  • If pre‑market starts at 7:00 AM ET: that equals 4:00 AM AZ during EDT or 5:00 AM AZ during EST.
• After‑hours conversion examples (most of Arizona):
  • If after‑hours ends at 8:00 PM ET: that equals 5:00 PM AZ during EDT or 6:00 PM AZ during EST.

Caveats for extended hours

• Availability: exact start and end times depend on your broker. Some brokers permit only certain order types during extended hours, while others restrict quotes or execution to particular hours.
• Liquidity and spreads: extended sessions generally have lower liquidity and wider spreads, higher volatility, and more frequent price gaps at the open and close.
• Execution risk: orders placed near or after the regular close may be queued, routed differently, or require special instructions (e.g., limit orders, extended‑hours consent).

As of 2025-12-31, exchange and broker documentation (including Nasdaq and major brokerage help pages) confirm that extended‑hours windows vary and that traders should verify their broker’s policies. For Bitget users, check platform notices and order execution policies in the app.

U.S. market holidays and half-days (impact on Arizona traders)

U.S. exchanges observe several market holidays during which the regular session is closed, and a small number of days with early or half‑day closes. Typical full‑day closures include New Year’s Day, Martin Luther King Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth, Independence Day (observed), Labor Day, Thanksgiving Day, and Christmas Day (observed). Some years include additional adjustments when holidays fall on weekends.

Half‑day early closes can occur on days such as the day after Thanksgiving and certain days adjacent to major holidays (e.g., partial hours on Christmas Eve). Exchange holiday calendars are published annually and occasionally adjusted.

How this affects Arizona trading

• When exchanges are closed for a full holiday, there is no regular trading: no 9:30 AM–4:00 PM ET session and no Arizona regular‑session times to map.
• On early‑close days, the exchange will publish the early close time in Eastern Time; convert that time to Arizona by applying the seasonal offset (subtract 3 hours during EDT; subtract 2 hours during EST).

Example: if an exchange announces an early close at 1:00 PM Eastern on a given day, that equals either 10:00 AM AZ (during EDT) or 11:00 AM AZ (during EST) for most of Arizona.

Important: holiday and early‑close schedules change year to year. Always confirm the current calendar from the exchanges or your broker.

Navajo Nation exception and practical implications

Most of Arizona stays on Mountain Standard Time (UTC−7) year‑round, but the Navajo Nation in northeastern Arizona observes daylight saving time, switching to Mountain Daylight Time (UTC−6) during the DST period.

Practical implications:

• Residents and traders in the Navajo Nation will see local clocks differ from nearby communities in Arizona during DST months — for example, a town outside the Navajo Nation may be 1 hour behind communities inside the Nation during DST.
• When converting trading hours, confirm whether the location in question observes DST (i.e., whether it is inside the Navajo Nation) to avoid placing orders at the wrong local time.
• For firms or traders operating across Arizona boundaries, clearly label times by both zone and whether DST applies (for example, say "1:00 PM MST (Arizona, most of year) / 2:00 PM MDT (Navajo Nation during DST)" to remove ambiguity).

This local exception is frequently the source of execution mistakes for retail traders and professionals alike — double‑check device time settings and broker timestamping.

Practical considerations for Arizona traders

1. Device and broker time settings
   • Most trading platforms and broker apps automatically display market times in your device or account time zone. Confirm that your device time is set correctly and that the broker recognizes your timezone (most will detect and display local times).
2. Order types and order routing near the close
   • Market‑on‑close, limit, and IOC/FOK orders may behave differently near or at the close. Be aware of how your broker handles close-of-day orders and whether they participate in official market-on-close mechanisms used by exchanges.
3. Placing intraday orders with processing margin
   • Execute early enough to allow for processing delays; network or routing issues near the close can delay or prevent execution. Avoid leaving critical adjustments to the last minute.
4. Watch for early closes and halts
   • Exchanges publish early‑close notices ahead of time. Additionally, market halts can occur intra‑day for news, volatility, or technical reasons — halts can impact order queues and executions.
5. Use Bitget tools and notices
   • For traders seeking a modern trading platform and wallet integration, Bitget provides platform notifications and order management tools. Check Bitget announcements for planned maintenance or schedule changes that might affect extended hours or settlement windows.

Sources and best practice: investor education groups and exchange pages recommend verifying both exchange calendars and broker notices before major events or holidays.

Common misconceptions and pitfalls

• Misconception: "Arizona follows Mountain Daylight Time in summer." Not true for most of Arizona — the state remains on MST year‑round. Only the Navajo Nation observes DST.
• Pitfall: relying on stale conversion tables. Some websites or printed materials show conversions that don’t account for DST exceptions or recent calendar shifts. Always verify with current exchange and broker information.
• Misinterpretation: assuming after‑hours prices are equivalent to regular session prices. Extended hours often have different liquidity and price behavior; do not assume equal fills or spreads.
• Device mismatch: smartphone or computer set to an incorrect time zone can cause your app to display wrong local times for order submission. Confirm device time settings and whether your trading app uses system time or account time.

Quick reference (regular & extended hours in Arizona)

Below is a compact reference you can print or memorize for quick conversions. These examples assume the standard 9:30 AM–4:00 PM Eastern session as the baseline.

• Regular session close (most of Arizona):

  • 4:00 PM Eastern = 1:00 PM AZ during EDT (mid‑March to early November)
  • 4:00 PM Eastern = 2:00 PM AZ during EST (early November to mid‑March)

• Regular session open (most of Arizona):

  • 9:30 AM Eastern = 6:30 AM AZ during EDT
  • 9:30 AM Eastern = 7:30 AM AZ during EST

• Typical pre‑market examples (if broker opens at 4:00 AM ET):

  • 4:00 AM ET = 1:00 AM AZ during EDT
  • 4:00 AM ET = 2:00 AM AZ during EST

• Typical after‑hours examples (if broker supports trading to 8:00 PM ET):

  • 8:00 PM ET = 5:00 PM AZ during EDT
  • 8:00 PM ET = 6:00 PM AZ during EST

Note: exact pre/post‑market times depend on your broker. Convert using −3 or −2 hour offset based on whether Eastern Time is on DST.

Frequently asked questions (FAQ)

Q: Does Arizona observe daylight saving time? A: Most of Arizona does not observe DST and stays on Mountain Standard Time (UTC−7) year‑round. The Navajo Nation is the notable exception and does observe DST.

Q: What time does after‑hours end in Arizona? A: After‑hours commonly ends at 8:00 PM Eastern on many venues, which converts to 5:00 PM AZ during EDT or 6:00 PM AZ during EST for most of Arizona. Verify with your broker because end times vary.

Q: Will my broker accept orders after 4:00 PM ET? A: That depends on your broker. Some brokers accept extended‑hours orders with restrictions on order types and sizes. Check your broker’s help pages or platform notifications. For Bitget users, review the Bitget app’s extended‑hours and order rules in the account settings.

Q: If I live inside the Navajo Nation in Arizona, what time is market close locally? A: If the Navajo Nation is observing DST (EDT period for Eastern), conversions differ: 4:00 PM Eastern often equals 2:00 PM local time in the Navajo Nation during DST and 1:00 PM local time during Eastern standard time. Always confirm locally.

Q: How should I plan orders near market close when I’m in Arizona? A: Place orders with time buffer, use limit orders to control execution price, and check whether your broker supports market‑on‑close instructions. Avoid last‑second submissions when possible.
