Stock market hours around the world

How global trading hours actually work

This guide covers eight of the largest equity exchanges: New York Stock Exchange and Nasdaq in the United States, the London Stock Exchange and Euronext Paris in Europe, the Japan Exchange Group in Tokyo, Hong Kong Exchanges and Clearing, the National Stock Exchange of India in Mumbai, and the Australian Securities Exchange in Sydney. Between them, their regular sessions cover about 20 to 22 hours of each weekday; the gap is the two to four hours between the New York close and the Sydney open, depending on where each hemisphere is in its DST cycle (two hours in the northern winter, four in the northern summer).

Each exchange publishes its hours in local civil time. That sounds harmless and is in practice the source of most cross-market scheduling errors. The NYSE's "09:30–16:00" only resolves to a UTC instant after you know whether the U.S. is on Eastern Standard Time (UTC-5, winter) or Eastern Daylight Time (UTC-4, summer). The LSE's "08:00–16:30" only resolves after you know whether the UK is on GMT (winter) or BST (summer). The JPX's "09:00–11:30 / 12:30–15:30" never has a DST adjustment because Japan does not observe DST ^[3]. The result is that New York is 5 hours behind London most of the year, but 4 hours behind for two or three weeks in March and one week around the start of November, when the U.S. and the UK have changed clocks on different dates. Tokyo is 13 hours ahead of New York in U.S. summer and 14 in winter.

The practical consequence: if you want to know "when is the LSE open in my local zone," the only safe answer is to compute it from the LSE's IANA zone (`Europe/London`) into your own IANA zone, with both DST schedules respected. The time zone converter does this for any date: enter the exchange's opening time in its own zone and read the result in yours. A static "LSE = 00:00–08:30 PT" lookup table is right most of the year and wrong for about four weeks, which is the hardest kind of error to notice.

One more point: the "regular session" hours that exchanges publicize are not the only times you can trade. Pre-market and after-hours sessions extend U.S. equity trading from roughly 04:00 to 20:00 ET. Asian markets typically have less extended-hours activity. European markets have closing-auction extensions but limited true after-hours. The exchange's headline hours are the auction-and-continuous-trading window only; what your broker actually lets you do may be wider.

The eight exchanges, their hours, and their quirks

New York Stock Exchange (NYSE). Regular session 09:30–16:00 America/New_York. Pre-market 04:00–09:30, after-hours 16:00–20:00 on most ECN routes. The opening auction prints a single cross at 09:30, the closing auction prints at 16:00; both are major liquidity events. The closing auction in particular is where index funds and rebalancing trades clear, and it regularly accounts for around a tenth of a stock's daily volume. Holidays follow most of the U.S. federal calendar plus Good Friday; the market closes early, at 13:00, on the day after Thanksgiving and usually on July 3 and December 24 when they fall on weekdays. NYSE observes U.S. DST ^[1] — the session shifts an hour in UTC at every transition.

Nasdaq Stock Market. Regular session is identical to NYSE: 09:30–16:00 America/New_York. The two markets have a shared regulatory framework (Reg NMS), and most stocks listed on either are traded on both via the National Market System. Nasdaq's pre-market opens at 04:00 ET and is the more active venue for early-session activity in tech names. Holidays match the NYSE calendar.

London Stock Exchange (LSE). Continuous trading 08:00–16:30 Europe/London, with an opening auction 07:50–08:00 and a closing auction 16:30–16:35 ^[2]. Half-day closes at 12:30 on Christmas Eve and New Year's Eve. Bank holidays apply. The LSE and NYSE regular sessions overlap for two hours most of the year.

Euronext Paris, continuous trading 09:00–17:30 Europe/Paris, after an opening auction that uncrosses at 09:00, with a closing auction that uncrosses at about 17:35. The other Euronext venues (Amsterdam, Brussels, Lisbon, Dublin, Oslo, Milan) run on the same schedule with minor differences. France observes EU DST, switching on the last Sunday of March and last Sunday of October.

Japan Exchange Group (JPX). Two sessions: morning 09:00–11:30 Asia/Tokyo, afternoon 12:30–15:30. The afternoon close moved from 15:00 to 15:30 on November 5, 2024, when the Tokyo Stock Exchange's upgraded *arrowhead* trading system went live and a new closing auction was added ^[6]. The midday lunch break is one of the few preserved in major world markets and is a common surprise for foreign investors. Japan does not observe DST, so JPX's UTC times are stable year-round: 00:00–02:30 UTC and 03:30–06:30 UTC.

Hong Kong Exchanges and Clearing (HKEX). Two sessions: morning 09:30–12:00 Asia/Hong_Kong, afternoon 13:00–16:00 ^[4]. One-hour midday break. Closing-auction session 16:00–16:10. Hong Kong does not observe DST. The Mainland-Hong Kong Stock Connect schemes have additional rules about which Chinese A-shares are tradable on which days; these are worth checking when investing in dual-listed names. HKEX used to suspend trading during typhoon signal 8 or higher and black rainstorm warnings; since September 23, 2024 it keeps trading in severe weather.

National Stock Exchange of India (NSE), regular session 09:15–15:30 Asia/Kolkata. Pre-open 09:00–09:15 with a single-price auction. India does not observe DST, so NSE hours map to a stable 03:45–10:00 UTC year-round. The Bombay Stock Exchange (BSE) runs on the same schedule. NSE's holiday list includes Hindu, Muslim, Christian, Sikh and Jain festivals as well as national days, and is published each December for the following year.

Australian Securities Exchange (ASX). Normal trading 10:00–16:00 Australia/Sydney (stocks open in staggered groups from 10:00), with a closing single-price auction at about 16:10. New South Wales observes Australian Eastern Daylight Time (UTC+11) from October to April and Australian Eastern Standard Time (UTC+10) from April to October — DST runs the opposite half of the year from the Northern Hemisphere. The ASX is on the opposite side of the Pacific from NYSE; their direct overlap is zero, and the two markets are best thought of as a relay rather than a pair.

To see any of these sessions in your own zone, convert its opening and closing times with the time zone converter; the world clock shows the current time in each exchange's city.

The overlaps that matter

Cross-market overlap is where institutional flow concentrates and where directional moves in one market most clearly transmit to the next.

LSE ↔ NYSE: the two-hour transatlantic overlap. The NYSE opens at 09:30 New York time, which is 14:30 in London, and the LSE closes at 16:30, so both are open for two hours: 13:30–15:30 UTC in summer and 14:30–16:30 UTC in winter. This window carries cross-Atlantic arbitrage, trading in stocks listed on both sides, and the U.S. morning's reaction to European news. During the desync weeks the NYSE opens at 13:30 London time and the overlap grows to three hours: in 2026 that was March 9–27 and October 26–30.

Tokyo ↔ Hong Kong: the Asian core overlap. Because both markets break for lunch, the overlap comes in three pieces: 01:30–02:30 UTC (both mornings), 03:30–04:00 UTC (Tokyo afternoon, Hong Kong morning) and 05:00–06:30 UTC (both afternoons), about three hours in total. After 06:30 UTC Hong Kong trades alone until its 08:00 UTC close.

ASX ↔ Tokyo / Hong Kong: the Asia-Pacific morning relay. The ASX opens at 23:00 UTC during the Australian summer (AEDT, October to April) and 00:00 UTC in the Australian winter, and closes at 05:00 or 06:00 UTC. It overlaps Tokyo's morning session from 00:00 UTC and Hong Kong from 01:30 UTC.

HKEX ↔ LSE: the bridge. When the UK is on BST, London opens at 07:00 UTC and overlaps Hong Kong's last hour of continuous trading (07:00–08:00 UTC). In winter, London opens at 08:00 UTC, as Hong Kong's continuous session ends, so the two barely overlap.

There is no NYSE ↔ Tokyo overlap. JPX closes at 06:30 UTC; NYSE opens at 13:30 or 14:30 UTC depending on season, seven to eight hours later. European markets trade through that gap, and index futures (CME, Eurex, SGX, Osaka) trade almost around the clock.

Holidays, half-days, and emergency closures

Each exchange publishes its annual holiday calendar in local civil time. The U.S. and UK exchange calendars share about four closures a year: New Year's Day, Good Friday, the last Monday of May (Memorial Day in the U.S., the spring bank holiday in the UK) and Christmas Day. Beyond that, there is no global trading-holiday standard.

The U.S. exchanges close on the federal-holiday subset that markets observe: New Year's, MLK Jr. Day, Presidents' Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving, and Christmas. Early-close days (13:00 ET) on the day after Thanksgiving, Christmas Eve, and Independence Day eve when those fall on a weekday. Unscheduled NYSE closures since 2000 include September 11–14, 2001 (reopening on September 17), October 29–30, 2012 (Hurricane Sandy), and national days of mourning for Presidents Reagan (June 11, 2004), Ford (January 2, 2007), George H. W. Bush (December 5, 2018) and Carter (January 9, 2025).

The LSE observes UK bank holidays plus a half-day at 12:30 on Christmas Eve and New Year's Eve. JPX closes on Japanese national holidays plus December 31 to January 3, and its Golden Week closures cluster in late April and early May. HKEX observes both Western holidays and the Chinese calendar — Lunar New Year (three days closed; the Mainland A-share market closes for a full week and that interacts with Stock Connect), Ching Ming, mid-Autumn, and others on a year-shifting lunar schedule. NSE India observes Hindu (Holi, Diwali), Islamic (Eid) and other religious holidays on a year-shifting lunisolar schedule; on Diwali it holds a one-hour special "Muhurat" trading session. ASX closes on the days listed in its own trading calendar (weekday closures in 2026: New Year's Day, Australia Day, Good Friday, Easter Monday, the King's Birthday, Christmas Day and Boxing Day; Anzac Day fell on a Saturday), with early closes on Christmas Eve and New Year's Eve.

Before placing an order in a market you do not trade every day, check that exchange's own published trading calendar for holidays and early closes. Unannounced closures (weather, national mourning) can still happen at short notice.

Pre-market, after-hours, and the order types you actually need

Many retail brokers offer pre-market and after-hours trading on U.S. equities through exchange extended-hours sessions and electronic communication networks (ECNs). These sessions are not the same as the regular session.

Pre-market session (04:00–09:30 ET). Lighter volume than regular hours. Spreads, especially on smaller stocks, can be much wider than during the day. Limit orders only at most brokers; market orders are typically rejected or queued for the regular open. Earnings released before the open are first priced into pre-market activity, and the regular open's auction print absorbs the cumulative pre-market direction.

After-hours session (16:00–20:00 ET). Earnings released after 16:00 ET get priced here. Large companies often report after the close, and the minutes after a release can see large moves. Volume usually thins out later in the evening session.

Closing auction (16:00 ET). Market-on-close (MOC) and limit-on-close (LOC) orders must normally be entered before 15:50 ET at NYSE or 15:55 ET at Nasdaq. Index funds use them heavily for end-of-day rebalancing. Check your broker's own cut-off, which is often earlier.

Opening auction (09:30 ET). Market-on-open (MOO) and limit-on-open (LOO) orders join the opening cross; each venue and broker sets its own entry cut-off, so check before relying on one.

MOC and LOC are not orders that "guarantee" a fill at the close. They guarantee participation in the closing auction at the auction-determined price. If the auction prints far from where you wanted to fill, you fill there.

This is general information, not investment advice. For most people who are not day-trading, limit orders during the regular session do the job. Market orders in the first and last minutes of the session risk poor fills, because spreads can widen around the auctions and in the first reaction to overnight news.

Foreign exchange and crypto: the markets that don't sleep

Equity exchanges set the rhythm of the trading day, but two other markets run continuously: FX and crypto.

Foreign exchange (FX) trades on a decentralized network of bank dealers, ECNs, and prime brokers. There is no single venue and no opening or closing bell. Liquidity follows the business day around the world: Asian hours are usually thinnest, London is the largest single FX trading centre in the BIS Triennial Survey, and the London–New York overlap is typically the busiest part of the day. The FX week conventionally runs from Sunday 17:00 New York time to Friday 17:00 New York time (21:00 or 22:00 UTC, depending on U.S. DST), and weekend activity is minimal.

Cryptocurrency trades 24/7/365 on centralized exchanges (Coinbase, Binance, Kraken, OKX, Bybit, etc.) and 24/7 on decentralized exchanges and on-chain protocols. There are no holidays, no opening bells, no closing auctions. Liquidity still varies by hour and is usually thinner at weekends, when prices can move more on smaller orders.

For the equity question — "is anything open right now?" — compare the current time in each exchange's city, on the world clock, with the sessions above, and check the holiday calendars. For continuous markets, the answer is always yes during the work week and almost always yes on weekends.

Glossary

Regular trading session

The continuous-trading window an exchange officially supports — typically the only window during which the exchange's order book is fully active and during which closing-auction prints are official. For the NYSE this is 09:30–16:00 America/New_York; for the LSE 08:00–16:30 Europe/London; for JPX two sessions, 09:00–11:30 and 12:30–15:30 Asia/Tokyo.

Closing auction

A single-price auction at the end of the regular session that establishes the official closing price for each listed security. Orders flagged as market-on-close (MOC) or limit-on-close (LOC) participate in the auction. Index funds use the closing auction heavily for daily rebalancing, which is why it regularly accounts for around a tenth of a U.S. stock's daily volume.

Pre-market and after-hours

Extended trading sessions, run by exchanges and ECNs, that allow trading before the regular open and after the close. U.S. pre-market runs roughly 04:00–09:30 ET; after-hours 16:00–20:00 ET. Spreads are wider, volume is lighter, and most brokers restrict order types to limits only.

ECN (Electronic Communication Network)

An electronic order-matching system that routes buy and sell orders for securities outside an exchange's central limit order book. ECNs power U.S. pre-market and after-hours trading, and they handle a substantial share of regular-session order flow under Regulation NMS. Major ECNs include Nasdaq INET, NYSE Arca, and Cboe BZX.

Market-on-close (MOC) order

An order that participates in the closing auction, executing at the official closing price determined by the auction. MOC orders must be entered before a cut-off (15:50 ET at NYSE, 15:55 at Nasdaq) and generally cannot be cancelled after it. Used heavily by index funds and rebalancing trades; an unhedged MOC order takes whatever closing price the auction produces.

IANA zone

The canonical identifier for a civil time zone, used by operating systems and programming languages for unambiguous time-of-day computation. Each exchange's hours are defined in a specific IANA zone — `America/New_York` for NYSE/Nasdaq, `Europe/London` for LSE, `Asia/Tokyo` for JPX, `Asia/Hong_Kong` for HKEX. Storing exchange hours as a fixed UTC offset rather than an IANA zone breaks at every DST transition.

Trading-day overlap

The window during which two exchanges are simultaneously open for regular trading. The most-watched overlap is LSE–NYSE, two hours most of the year (14:30–16:30 London time). It grows to three hours in the weeks each spring and autumn when the U.S. and Europe have changed clocks on different dates.
