What Time Does the Stock Market Close in Arizona?
The US stock market close time in Arizona is 1:00 PM Mountain Standard Time (MST), every regular trading day, all year round.
Arizona does not observe daylight saving time. That single fact makes Arizona one of the easiest US states for tracking market hours, because the close time never shifts. While most of the country moves their clocks forward in spring and back in autumn, Arizona stays fixed. The New York Stock Exchange (NYSE) and Nasdaq both close at 4:00 PM Eastern Time, and because Arizona permanently sits two hours behind Eastern Time, that translates to a clean 1:00 PM local close, no matter the season.
If you are an Arizona resident watching the close bell, set your reminder for 1:00 PM and never adjust it. If you want to understand what time the stock market opens in Arizona, the same fixed two-hour offset applies: the market opens at 6:30 AM MST. Readers curious about how Arizona’s close compares to the Pacific Coast can check market close time in California, where daylight saving creates seasonal shifts.
The consistency is the story. Most trading questions have conditional answers. Arizona’s answer never changes.
Why Arizona’s Time Zone Makes Market Hours Uniquely Simple
Arizona runs on Mountain Standard Time permanently. That is the short answer. Unlike every other state in the contiguous US (except parts of Indiana in the past), Arizona does not spring forward or fall back, so the state’s offset from Eastern Time is always exactly two hours.
Most US states go through two different offsets each year. During standard time, Mountain states like Colorado and Utah are two hours behind Eastern Time. During daylight saving time, those same states shift to only one hour behind Eastern. Arizona, however, skips that shift entirely. The offset stays at minus two hours from ET, which means market hours stay fixed.
This matters practically. Traders in Colorado, for example, see the NYSE close at 2:00 PM local time in winter but at 3:00 PM local time in summer. Arizona traders see it at 1:00 PM, always. For anyone building a trading routine or scheduling client calls around the close, that consistency removes a genuine source of error.
The only exception worth knowing: the Navajo Nation, which lies partly within Arizona, does observe daylight saving time. If you are based in that area, you will need to account for the seasonal shift locally, even though Arizona state time does not change.
For a broader view of how stock market opening times across America work, the principle is the same everywhere: all US exchanges run on Eastern Time, and your local close depends entirely on your offset from ET.
US Stock Market Hours in Arizona: Complete Time Reference
All major US equity exchanges use Eastern Time as their reference clock. For Arizona traders on MST, the offset is a constant minus two hours. The table below covers every session you are likely to encounter.
| Session | Eastern Time (ET) | Arizona Time (MST) | Notes |
|---|---|---|---|
| Pre-market trading | 4:00 AM - 9:30 AM | 2:00 AM - 7:30 AM | Available on most brokers; wide spreads, low liquidity |
| Regular market open | 9:30 AM | 7:30 AM | NYSE and Nasdaq official open |
| Regular market close | 4:00 PM | 2:00 PM | NYSE and Nasdaq official close |
| After-hours trading | 4:00 PM - 8:00 PM | 2:00 PM - 6:00 PM | Available on most brokers; thin markets, higher risk |
Important correction on the close time: Several sources cite 1:00 PM for Arizona, which applies when they compare to Mountain Daylight Time states. The precise answer depends on the season in the rest of the country. During standard time (roughly November to March), Arizona and Mountain Time states share the same offset, putting the close at 2:00 PM MST. During daylight saving time (roughly March to November), when the rest of the Mountain zone moves to MDT, Arizona stays on MST and the close appears to shift to 1:00 PM relative to Mountain states. Against Eastern Time directly, Arizona is always minus two hours, making the close 2:00 PM MST in standard time months and 1:00 PM MST in the daylight saving months when ET moves forward. The key is that Arizona itself does not move; Eastern Time does.
For reference on exchange hours directly, stock market opening time in New York and New York market open time both explain the ET anchor that all other times flow from.
NYSE and Nasdaq keep identical regular session hours. Both open at 9:30 AM ET and close at 4:00 PM ET. The exchanges differ in structure and the stocks listed on them, but for the purpose of tracking the market close, they are the same.
Extended-hours trading carries meaningful risk. Spreads between the bid and ask price widen significantly outside regular hours, and news-driven moves can be sharp and poorly priced. Unless you have a specific reason to trade pre-market or after-hours, most general guidance suggests waiting for the regular session when liquidity is deepest.
How Arizona Market Close Time Compares to Other US States
Arizona’s close time sits one hour earlier than most Mountain zone states during summer, and at the same time as them during winter. That is the concise version. The variation comes entirely from daylight saving time, which Arizona skips.
The table below shows close times across representative US states during both daylight saving time (DST) months and standard time months.
| State | Time Zone (Standard) | Close Time (DST months) | Close Time (Standard months) |
|---|---|---|---|
| New York | Eastern (ET) | 4:00 PM EDT | 4:00 PM EST |
| Florida | Eastern (ET) | 4:00 PM EDT | 4:00 PM EST |
| Illinois | Central (CT) | 3:00 PM CDT | 3:00 PM CST |
| Colorado | Mountain (MT) | 2:00 PM MDT | 2:00 PM MST |
| Arizona | Mountain (no DST) | 1:00 PM MST | 2:00 PM MST |
| California | Pacific (PT) | 1:00 PM PDT | 1:00 PM PST |
| Washington | Pacific (PT) | 1:00 PM PDT | 1:00 PM PST |
Notice that California and Arizona share a 1:00 PM close during DST months, even though they are in different time zones. That alignment disappears in winter, when Arizona shifts to 2:00 PM and California stays at 1:00 PM. Understanding this table removes a common point of confusion for traders who travel between states or follow mixed-state schedules.
For Pacific state readers, market close time in California and stock market open time in California go into further detail on how Pacific traders experience the trading day.
The practical takeaway: if you are trading from Arizona and comparing notes with someone in Colorado, your close times will differ by one hour during DST season and align during standard time. Keep that seasonal shift in mind when coordinating with traders or advisors in other Mountain states.
Stock Market Holidays and Early Close Days in Arizona
US equity exchanges are closed on certain public holidays each year, and those closures apply uniformly regardless of your state. Arizona traders observe the same holiday schedule as traders in New York.
The standard NYSE and Nasdaq holiday schedule includes the following dates each year:
- New Year’s Day (1 January)
- Martin Luther King Jr. Day (third Monday in January)
- Presidents’ Day (third Monday in February)
- Good Friday (the Friday before Easter Sunday)
- Memorial Day (last Monday in May)
- Juneteenth National Independence Day (19 June)
- Independence Day (4 July)
- Labor Day (first Monday in September)
- Thanksgiving Day (fourth Thursday in November)
- Christmas Day (25 December)
When a holiday falls on a Saturday, the market typically closes the preceding Friday. When it falls on a Sunday, the Monday is usually observed instead.
In addition to full-day closures, the exchanges observe early close days on the afternoon before certain holidays, typically Christmas Eve and the day after Thanksgiving. On early close days, the regular session ends at 1:00 PM ET, which translates to 11:00 AM MST in Arizona during DST months or to noon MST during standard time months.
Because exact dates shift each year and occasional changes do occur, always confirm the current year’s holiday schedule directly with the NYSE or Nasdaq before assuming a full trading day. Relying on assumptions around a holiday close is a straightforward way to miss a trade or leave an order sitting unexecuted.
Trading US Markets from South Africa: What Arizona Hours Mean for You
If you are a South African investor accessing US markets, Arizona market hours translate to late evening and early morning sessions in South Africa. South Africa Standard Time (SAST) runs at UTC+2 year-round. Arizona runs at UTC-7 during DST months and UTC-7 also during standard time (MST is UTC-7 permanently). That puts SAST nine hours ahead of Arizona during most of the year.
Here is the quick SAST conversion reference:
- Pre-market opens (2:00 AM MST / DST months): 11:00 AM SAST
- Regular session opens (7:30 AM MST / DST months): 4:30 PM SAST
- Regular session closes (1:00 PM MST / DST months): 10:00 PM SAST
- After-hours session closes (6:00 PM MST / DST months): 3:00 AM SAST (next day)
During standard time months (roughly November to March in the Northern Hemisphere), the regular session opens at 7:30 AM MST and closes at 2:00 PM MST, which maps to 4:30 PM SAST open and 11:00 PM SAST close.
South African investors who hold US-listed shares or ETFs through local platforms or direct offshore accounts need to be aware that placing orders during South African business hours often means trading in the pre-market window, where liquidity is thin and prices less reliable. Limit orders rather than market orders are generally more sensible during those hours.
For South Africans considering a move to the US, the financial planning guide for South Africans moving to America covers the broader context. If you are investing offshore from South Africa while remaining resident, the same session timing principles apply regardless of which US state the exchange is located in.
Practical Tips for Trading Around the Arizona Close
The most effective trades during the closing minutes of a session require preparation beforehand, not reaction in the moment. The Arizona close lands at either 1:00 PM or 2:00 PM MST depending on the season, and markets can be volatile in the final thirty minutes as institutional orders flood in.
Keep these practical points in mind:
- Set calendar reminders for both seasonal close times. Program an alert for 1:00 PM MST and one for 2:00 PM MST, and note which is active based on whether DST is in effect in the Eastern zone.
- Avoid placing market orders in the final ten minutes of regular trading if precision matters. Prices can move sharply in the closing auction period.
- Use limit orders rather than market orders during pre-market and after-hours sessions. The spread between bid and ask can be wide, and a market order may fill at a worse price than you expect.
- Check the holiday schedule before any long weekend. An unexpected market closure or early close can leave a time-sensitive order sitting overnight.
- If you are a South African investor, accept that the regular session close in Arizona falls at 10:00 PM or 11:00 PM your time. Automated orders placed before you go to sleep are more reliable than trying to monitor a late-night close.
Sound discipline around order types and timing is a cornerstone of sound retirement planning and investment advice, especially for long-term investors who rely on US market exposure as part of a diversified offshore allocation.

The NYSE closes at 4:00 PM Eastern Time, which is 1:00 PM MST in Arizona during daylight saving months and 2:00 PM MST during standard time months. Arizona itself does not change its clocks, so the apparent shift comes from Eastern Time moving forward in spring.
Does Arizona change its clocks for daylight saving time?
No. Arizona does not observe daylight saving time. The state remains on Mountain Standard Time (MST, UTC-7) throughout the entire year. The Navajo Nation within Arizona is an exception and does observe daylight saving time.
What time does the stock market close in Arizona during summer?
During the summer months, when the rest of the US is on daylight saving time, the stock market closes at 1:00 PM MST in Arizona. Eastern Time is two hours ahead of Arizona during this period, so the 4:00 PM ET close lands at 1:00 PM locally.
What time does the stock market open in Arizona?
The regular market session opens at 9:30 AM Eastern Time, which is 7:30 AM MST in Arizona year-round. For a full breakdown, stock market open time in Arizona covers pre-market hours as well.
Can I trade stocks after 1:00 PM in Arizona?
Yes. After-hours trading is available through most brokers from 4:00 PM to 8:00 PM ET, which is 2:00 PM to 6:00 PM MST in Arizona during DST months. Be aware that after-hours sessions carry wider spreads, lower liquidity, and higher price volatility than the regular session.
What time does the Nasdaq close in Arizona?
Nasdaq closes at the same time as the NYSE: 4:00 PM Eastern Time, which is 1:00 PM MST in Arizona during DST months and 2:00 PM MST during standard time months. The two exchanges maintain identical regular session hours. For a broader reference on US stock market opening hours, the Eastern Time anchor applies to all major US equity exchanges.
The Bottom Line on Arizona Stock Market Close Times
Arizona’s fixed time zone makes the market close simpler to track than in almost any other US state. The regular session closes at 4:00 PM Eastern Time, which is 1:00 PM MST during daylight saving months and 2:00 PM MST during standard time months. Arizona never adjusts its clocks, so any variation you notice is Eastern Time moving, not Arizona.
For South African investors, the close lands between 10:00 PM and 11:00 PM SAST, which means most active monitoring happens after business hours locally.
