US Stock Market Hours Around the World

US stock market hours run from 9:30 a.m. to 4:00 p.m. New York time, Monday through Friday. Converted into other clocks, that same session sits at 14:30 to 21:00 in London, 21:30 to 04:00 the next morning in Singapore, and 22:30 to 05:00 in Tokyo, as of July 2026. This page maps the regular and extended US sessions onto the major world time zones, walks the daylight saving shifts that move the conversion twice a year, and shows where the holiday calendar fits.

US market hours in major world time zones

Everything the US market does is scheduled in Eastern Time, the clock New York keeps. Eastern Time runs at UTC-5 in winter and UTC-4 during daylight saving. The panel below converts the four boundaries of a US trading day, the 4:00 a.m. premarket start, the 9:30 a.m. opening bell, the 4:00 p.m. closing bell, and the 8:00 p.m. after-hours cutoff, into ten local clocks. The rows are a fixed illustrative reference for July 2026, the half of the year when New York keeps daylight time. Winter figures come later on this page.

Read the last column first. Singapore sits 12 hours ahead of New York in this window, and the opening bell lands there at 21:30 local with the closing bell at 04:00 the following morning. Tokyo runs one hour further ahead again at 13. London, 5 hours ahead, gets the friendliest conversion of the ten: the US open at 14:30 leaves a full London afternoon alongside New York's morning, and the US close at 21:00 arrives before midnight.

The extended windows stretch the same day considerably. A Sydney reader following the whole electronic session watches it begin at 18:00 in the evening and end at 10:00 the next morning, sixteen hours straddling local midnight. In Los Angeles, three hours behind New York, the entire regular session fits inside a local working day at 06:30 to 13:00.

Which session are you converting?

A US trading day stacks three windows, and a conversion is only useful when it names which one it converts.

• Regular session, 9:30 a.m. to 4:00 p.m. ET. The six and a half hours the opening and closing bells bracket. Official opening and closing prices come from auctions at each end of it.
• Premarket, 4:00 a.m. to 9:30 a.m. ET. Electronic trading ahead of the opening bell.
• After-hours, 4:00 p.m. to 8:00 p.m. ET. Electronic trading after the closing bell.

The regular session is what index levels, the closing price on your statement, and the evening news all describe. The two extended windows are thinner, carry wider bid-ask spreads, and are usually limit-order only at retail brokers. Premarket and after-hours trading measures those differences on the tape. For every boundary stated plainly in Eastern Time, see stock market hours.

Daylight saving moves half the conversions

Time zone conversions for the US market are not stable across the year, and the instability is one sided. The United States observes daylight saving from the second Sunday in March to the first Sunday in November, which in 2026 means March 8 through November 1. Much of Asia observes none at all. Europe observes its own, on its own dates. Three patterns fall out of that mix.

• Europe moves alongside New York, mostly. London and Frankfurt shift their clocks in the same direction, and their local reading of the 9:30 a.m. bell holds at 14:30 and 15:30 for most of the year.
• Asia does not move, so the conversion does. Tokyo, Singapore, Hong Kong and Mumbai keep one clock year round. When New York springs forward, the local time of the US open steps one hour earlier in each of them.
• Sydney moves the opposite way. Australian eastern daylight time runs during the southern summer, roughly October to April, the opposite half of the calendar from the US shift. The two changes stack rather than cancel.

The last column is the size of the annual swing. London and Frankfurt read 0: their January and July conversions are identical. Tokyo reads 1, the opening bell moving from 23:30 in January to 22:30 in July. Sydney reads 2, the widest swing of the six, with the bell at 01:30 the following morning in January against 23:30 the same evening in July.

The weeks when Europe and the US disagree

The United Kingdom and the European Union change clocks on the last Sunday in March and the last Sunday in October. The United States changes on the second Sunday in March and the first Sunday in November. Two mismatch windows open every year. In 2026 they run March 8 to March 29, when New York keeps daylight time and London does not, and October 25 to November 1, when London has already moved back and New York has not. Inside both windows the London reading of the 9:30 a.m. bell sits at 13:30 rather than 14:30, and every US session boundary arrives one hour earlier than a London reader expects. Calendar entries and price alerts set months in advance drift by that hour twice a year.

Overlap with your local exchange

Local exchange hours and US hours overlap only in places. The London Stock Exchange runs 8:00 a.m. to 4:30 p.m. local, and its final two hours sit alongside the first two hours of New York's regular session in July 2026. The Tokyo Stock Exchange runs 9:00 a.m. to 3:30 p.m. local with a lunch break, entirely inside the US overnight. A reader in Singapore or Tokyo who wants the US regular session lives with a late night, an early morning, or an order left resting.

An order placed while the US market is shut does not simply wait quietly. A market order entered overnight queues for the next opening auction, and the price it meets is set by the crowd that arrives at 9:30 a.m. ET, not by the last after-hours print. Mutual fund orders behave differently again: they execute once a day at the net asset value struck after the 4:00 p.m. close, whatever local hour you sent them in, as when mutual funds trade walks through.

The days the conversion does not apply

US exchanges close on weekends, on roughly ten full holidays a year, and early at 1:00 p.m. ET on a handful of scheduled half days. On a half day every boundary in the first panel moves three hours earlier, and after-hours trading wraps around 5:00 p.m. ET instead of 8:00 p.m. Holidays elsewhere have no effect on the US calendar: a US-listed stock trades on Boxing Day and through Golden Week, and stands still on Thanksgiving. Market holidays and early closes carries the dated calendar.

US market hours worldwide FAQ

What time does the US stock market open in the UK?

The 9:30 a.m. New York open lands at 2:30 p.m. London time for most of the year, with the 4:00 p.m. close at 9:00 p.m. For roughly three weeks in late March and one week in late October, when the two regions have not yet aligned their clock changes, the open sits at 1:30 p.m. London time instead.

What time does the US stock market open in Tokyo and Singapore?

As of July 2026, the New York open lands at 10:30 p.m. in Tokyo and 9:30 p.m. in Singapore, with the close at 5:00 a.m. and 4:00 a.m. the next morning. Between early November and early March each of those local times moves one hour later.

Does the US market open at the same local time all year?

Only where the local region changes its clocks on the same dates New York does. The UK and continental Europe hold their conversion steady for most of the year, Asian cities without daylight saving see it move one hour twice a year, and Sydney sees two hours.

How do I convert US market hours to my own time zone?

Take 9:30 a.m. and 4:00 p.m. Eastern Time, note whether New York is on UTC-5 (early November to early March) or UTC-4 (early March to early November), then add your own offset from UTC. The panels above do that arithmetic for ten cities as a static July 2026 reference.

Can I trade US stocks from overseas outside regular hours?

Extended-hours sessions run 4:00 a.m. to 9:30 a.m. and 4:00 p.m. to 8:00 p.m. ET, which covers a wider slice of the world's waking hours, and access depends on what your broker supports. Those windows carry fewer participants and wider spreads than the regular session.

Market hours are a schedule, and a schedule converts cleanly once you know which clock it was written in. To measure how a session actually behaves in any window you pick, run the queries yourself on the Strasmore terminal.
