Here is when the biggest global stock markets are open for business

A stock market exchange is, by definition, a marketplace where stocks can be bought and sold for certain hours throughout the day. It functions as an entity that ensures orderly trading and efficient dissemination of price quotes for the companies that list on the exchange.

Trading is generally conducted from Monday through Friday. The Saudi Stock Exchange is an exception to the rule, as it is open from Sunday to Thursday.
A small number of exchanges close for a lunch break. This is most commonly seen in Asia’s marketplaces. The London Stock Exchange has a two-minute break at noon daily.
For an American investor, access to any of the international markets and exchanges requires an account with a brokerage, online or off.


Trading Hours on Holidays
Holidays depend on the local calendar, so they are different for every location. The New York Stock Exchange (NYSE) closes on July 4 for U.S. Independence Day. The Singapore Stock Exchange closes in early February for the Chinese New Year.

Some exchanges close for a half day from time to time. For example, the NYSE is open only until 1 p.m. on Christmas Eve.
The exchanges post their annual calendars well in advance.


Trading Hours in Asia and the Mideast
There are 11 time zones across Asia and its immediate neighbors, but fortunately, they synchronize their exchange hours for the sake of trade and liquidity.

Some Asian markets, including the Shanghai Stock Exchange (SSE) and the Tokyo Stock Exchange (TSE/TYO), take a break for lunch.

The Shanghai Stock Exchange has 18 market holidays in a year, including a five-day hiatus for the Chinese New Year.


Trading Hours in the U.K. and Europe--
Europe, like Asia, has many individual exchanges. The largest stock exchange organization in Europe is Euronext, a pan-European exchange that operates in seven countries and has its headquarters in Amsterdam.


Trading Hours in South America--
The largest exchange in South America is in São Paulo, Brazil. The exchange trades two hours ahead of the NYSE, so much of the action follows that of the NYSE.


Trading Hours in Africa--
The largest stock exchange in Africa is in Johannesburg, South Africa. Egypt, Mauritius, and Nigeria have smaller exchanges.

The Johannesburg Stock Exchange (JSE) has acquired the South Africa Futures Exchange and the Bond Exchange of South Africa, so all of those assets are traded on the JSE.
The Johannesburg exchange is open from 9 a.m. to 5 p.m. South African Standard Time (SAST), with no lunch break. The exchange, therefore, opens 6½ hours before the NYSE.


Trading Hours in Australia/Oceania--
The Sydney-based Australian Securities Exchange (ASX) is roughly the same size as the South African exchange. The ASX merged with the Sydney Futures Exchange in 2006. Bonds and derivatives also are traded on the ASX.

The market opens later than most, at 10 a.m. local time, and there is no lunch break.

The world’s first public stock market was established in Amsterdam in 1611. It initially offered only shares in the Dutch East Indies Co.


What's the Difference Between a Stock Exchange and the Stock Market?--
A stock exchange is a marketplace or infrastructure that facilitates equity trading. The exchange is founded and managed by a corporation, private or public. It allows companies to list their stocks in its marketplace.

The term “stock market” refers more generally to all stocks, or to a group of stocks in a particular region, industry, or sector.


Which Major Stock Exchanges Are Closed During Lunch?--
The major stock exchanges with an official lunch close are the Shanghai Stock Exchange (SSE), the Tokyo Stock Exchange (TSE/TYO), the Shenzhen Stock Exchange (SZSE), and the Stock Exchange of Hong Kong (SEHK).

The London Stock Exchange (LSE) has a two-minute break at noon. Its traders don’t eat that fast. The mini-break is designed to protect institutional traders from high-frequency traders, whose split-second transactions can skew prices.


What Times Are the New York Stock Exchange (NYSE) and the Nasdaq Open?--
The New York Stock Exchange (NYSE) and the Nasdaq are usually open at the same hours, from 9:30 a.m. to 4 p.m. Eastern time.
Both publish annual calendars of their holidays and half days.
