US Stock Market Hours for International Traders

The regular US stock market session runs from 9:30 a.m. to 4:00 p.m. Eastern Time, Monday through Friday, except exchange holidays. Exchange premarket trading can start at 4:00 a.m. ET and after-hours trading can run to 8:00 p.m. ET, while overnight access depends on your broker. The number that trips up international traders is the offset: New York switches between EST (UTC−5) and EDT (UTC−4) on its own dates, so your local opening time moves by an hour twice a year, and in Europe it moves twice more for a week or three in spring and autumn.

The US trading day, anchored in Eastern Time

Every US equity schedule is published in Eastern Time, the clock of America/New_York. Writing "9:30 a.m. EST" all year is a small but real error: for about eight months New York is on daylight time.

The core session, 9:30 a.m. to 4:00 p.m. ET with no lunch break, includes the opening and closing auctions. The NYSE holidays and trading hours page lists that core session along with holidays and early closes. Around it sit extended hours. At the exchange level, Nasdaq's order types reference defines System Hours of 4:00 a.m. to 8:00 p.m. ET next to Market Hours of 9:30 a.m. to 4:00 p.m.

What you can actually trade is narrower and set by your broker. Schwab's extended-hours page lists a standard premarket window of 7:00 to 9:25 a.m. and after-hours from 4:05 to 8:00 p.m. ET, with round-the-clock weekday trading only on thinkorswim and only for selected symbols. Overnight sessions are broker products as well: Interactive Brokers' overnight trading runs from 8:00 p.m. to 3:50 a.m. ET, and E*TRADE's extended hours agreement sets its overnight session at 8:00 p.m. to 4:00 a.m. ET, Sunday through Thursday. Eligible symbols, order types, and trade-date rules differ by platform.

Converting Eastern Time to your local time

Convert through UTC for a specific date rather than memorizing a gap between your city and New York. When New York is on EDT, premarket at 4:00 a.m. ET is 08:00 UTC and the regular session runs from 13:30 to 20:00 UTC. When New York is on EST, everything moves one hour later in UTC: premarket at 09:00 UTC and the regular session from 14:30 to 21:00 UTC. Add your own current UTC offset and you have local time.

For several major hubs, the regular session looks like this, first under US daylight time and then under US standard time:

1. London: 2:30–9:00 p.m. in both seasons, because the UK changes clocks too; Frankfurt, Paris, and Berlin: 3:30–10:00 p.m. in both seasons.
2. Dubai (UTC+4, no daylight saving): 5:30 p.m.–midnight in summer, 6:30 p.m.–1:00 a.m. in winter.
3. Tashkent and Almaty (UTC+5, no daylight saving): 6:30 p.m.–1:00 a.m. in summer, 7:30 p.m.–2:00 a.m. in winter.
4. Mumbai and New Delhi (UTC+5:30, no daylight saving): 7:00 p.m.–1:30 a.m. in summer, 8:00 p.m.–2:30 a.m. in winter.
5. Singapore (UTC+8, no daylight saving): 9:30 p.m.–4:00 a.m. in summer, 10:30 p.m.–5:00 a.m. in winter.

East of Dubai, the US close falls on the next calendar date: a Tashkent trader closing at 2:00 a.m. on Tuesday in winter is making Monday's trade. Keep both the time and the date in your notes for anything tied to a trade date. For Asian traders, premarket also starts early enough to matter: 4:00 a.m. ET is 4:00 p.m. in Singapore under US daylight time and 5:00 p.m. in winter.

The weeks when the gap with New York changes in 2026 and 2027

According to NIST's daylight saving time rules, US daylight time starts at 2:00 a.m. on the second Sunday in March and ends at 2:00 a.m. on the first Sunday in November. In 2026 that is March 8 to November 1. Applying the same rule, 2027 runs from March 14 to November 7.

Europe uses different Sundays. The European Commission's summertime rules set the switch for the last Sunday of March and the last Sunday of October, and the UK follows the same pattern, with GOV.UK listing March 29 and October 25, 2026, and March 28 and October 31, 2027. Because the US moves earlier in spring and later in autumn, there are two stretches each year when the usual European conversion is off by an hour and the US market opens at 1:30 p.m. in London and 2:30 p.m. in Frankfurt instead of 2:30 and 3:30.

In 2026 the spring stretch covered the trading days from March 9 to March 27, a full three weeks, and the autumn stretch runs from Monday, October 26, to Friday, October 30. In 2027 the spring stretch runs from March 15 to March 25, since Good Friday on March 26 is an exchange holiday, and the autumn stretch runs from Monday, November 1, to Friday, November 5. On the Mondays after, March 30, 2026, November 2, 2026, March 29, 2027, and November 8, 2027, the familiar London and Frankfurt times return.

Countries that do not observe daylight saving time, including the UAE, India, Singapore, Uzbekistan, and Kazakhstan, which has used a single UTC+5 zone since March 2024, see only the US changes. Their session moves one hour later from Monday, November 2, 2026, one hour earlier from Monday, March 15, 2027, and one hour later again from Monday, November 8, 2027. Traders in the southern hemisphere, where local clocks move in the opposite direction, can see the gap change by up to two hours across the year and should convert date by date.

A worked example: the market that "opened late"

A trader in Tashkent follows ABC and has always thought of the US open as 6:30 p.m. local time. On Friday, October 30, 2026, that is correct: New York is still on EDT, so 9:30 a.m. ET is 6:30 p.m. in Tashkent and the session closes at 1:00 a.m. on Saturday.

Over the weekend New York falls back to EST. Tashkent's clocks stay where they are. On Monday, November 2, the trader logs in at 6:25 p.m. expecting the open in five minutes, but it is only 8:25 a.m. in New York. ABC is quoted $49.90 bid and $50.30 ask in premarket, and the trader sends a regular-session Day order to buy 300 shares with a $50.10 limit. The broker accepts it and holds it for the regular session. It is visible on screen but not working, because the order was never flagged for extended hours.

At 7:30 p.m. Tashkent time ABC opens at $50.65, above the limit, and the order sits unfilled. Two separate issues are at work. The scheduling mistake left the order held rather than working for an hour. The price mistake means that even an extended-hours order at $50.10 would not have crossed a $50.30 offer. The broker's order status is the fastest way to separate them, a distinction hi2morrow explains in its guide to why an order can be rejected or held outside market hours.

Exchange hours, broker access, and the 23-hour day from December 6, 2026

An exchange being open does not mean your account can trade there. Four conditions have to line up: the venue is in session, your broker accepts and routes orders for that session, the security is eligible, and the order itself carries the right type, time in force, and session flag. Brokers are allowed to set narrower hours, limit order types, and choose their venues, and FINRA's extended-hours trading guidance warns that these sessions usually bring thinner liquidity, wider spreads, and quotes that can differ between venues.

The exchange side of the schedule is about to get much longer. NYSE and Nasdaq plan to launch overnight sessions on December 6, 2026, as summarized in Jones Day's review of the 23-hour trading day. The overnight session will run from 9:00 p.m. to 4:00 a.m. ET, with a pause from 8:00 to 9:00 p.m. ET each weekday. NYSE Arca will carry the overnight session for NYSE-listed stocks, and retail traders can reach it only through a member broker. The CTA extended trading hours FAQ sets the consolidated feed to run from 9:00 p.m. ET on Sunday to 8:00 p.m. ET on Friday, and says the overnight session will not open on the evening before a market holiday.

For traders in Asia and the Gulf, that session moves into local business hours. Under US standard time, which applies at launch, 9:00 p.m. to 4:00 a.m. ET is 02:00 to 09:00 UTC: 6:00 a.m. to 1:00 p.m. in Dubai, 7:00 a.m. to 2:00 p.m. in Tashkent and Almaty, 7:30 a.m. to 2:30 p.m. in Mumbai, and 10:00 a.m. to 5:00 p.m. in Singapore. The first session, on the evening of Sunday, December 6, in New York, opens at 10:00 a.m. on Monday in Singapore. Every one of those times moves an hour earlier when the US returns to daylight time on March 14, 2027. Whether you can use the session will still depend on your broker's rollout, the symbols it enables, and the order types it accepts overnight.

Holidays, early closes, and products on different clocks

The 9:30-to-4:00 frame applies only to a normal US trading day. On holidays the exchanges are closed, and on early-close days, November 27 and December 24 in 2026, the regular session ends at 1:00 p.m. ET. Extended-hours schedules on those days vary widely by venue and broker, as explained in hi2morrow's guide to extended-hours trading on an early close day. A public holiday in your own country has no effect on the US calendar, and a US bank holiday such as Columbus Day can leave the stock market open while settlement pauses.

The 23-hour schedule adds its own holiday rule. Nasdaq's global trading hours FAQ says that when a holiday falls on a Monday through Thursday, trading restarts at 9:00 p.m. ET on the evening of the holiday, so a Monday holiday is followed by a session from 9:00 p.m. Monday to 8:00 p.m. Tuesday. A Friday holiday leaves a longer gap. For Christmas on Friday, December 25, 2026, the CTA FAQ lists no session on Thursday night, during the holiday, or on Friday night, with the next one starting on Sunday, December 27, at 9:00 p.m. ET, which is 7:00 a.m. on Monday in Tashkent. The rest of the new schedule, including order types and trade dates overnight, is covered in hi2morrow's guide to what changes when US stocks trade 23 hours a day.

Other instruments follow their own timetables. Some index and ETF options trade until 4:15 p.m. ET, futures run on exchange schedules with daily maintenance breaks, and mutual funds price once a day at net asset value. A single stock can also be halted while its market stays open.

Alexander Styopin's professional view: an international trader should keep one fixed reference, the opening bell at 9:30 a.m. in New York, and let a time-zone-aware calendar work out local time for each date. Most timing mistakes come from a remembered local time that was right in August and wrong in the last week of October. Put the transition weeks in your calendar before they arrive, and after December 6, 2026, check your broker's overnight session terms before assuming the new exchange hours apply to your account.
