The US stock market does not operate every day of the year. In addition to weekend closures, US exchanges observe a series of official market holidays each year where US exchanges are completely shut for trading. While these are largely aligned with the U.S. federal holiday schedule, they are followed by major U.S. stock exchanges like the New York Stock Exchange (NYSE) and Nasdaq, global investors, brokers and financial institutions.Knowing when the US stock market is closed is important to the market participants for planning their strategy, portfolio planning, risk management, settlement timeline and global market coordination, especially for Indian investors who track US equities, ETFs, and Global indices. Below is a closer look at the standard weekend and other market holidays observed in the U.S. stock market.Standard weekend holidaysThe U.S. stock market is always closed on weekends, Saturday and Sunday, as part of standard stock market operation. Additionally, when a holiday occurs on a weekend, the exchanges observe the holiday the previous Friday or the following Monday, depending on the calendar arrangement. Official US stock market holidays (NYSE & Nasdaq)The following table provides a list of standard annual holidays observed by the NYSE and the Nasdaq.

For example, on the date after Thanksgiving and on Christmas Eve in 2026, the markets will close early at 1:00 p.m. ET (1:15 p.m. for eligible options). Crossing session orders will be accepted between 1:00 p.m. and 1:30 p.m., and late trading sessions for NYSE American Equities, NYSE Arca Equities, NYSE Chicago, and NYSE National will close at 5:00 p.m. ET.Bond market holidaysThe US bond markets observe the same 10 holidays as the US stock market and two additional holidays on Columbus Day (Monday, October 12) and Veterans Day (Wednesday, November 11). The bond markets also have several early closures at 2:00 PM ET in 2026. These include: DateEventApril 2Thursday before Good FridayMay 22Friday before Memorial DayJuly 2Day preceding Independence DayNovember 27Black Friday (the day after Thanksgiving)December 24Christmas EveDecember 31New Year's Eve Impact of weekend holidaysWhen a US stock market holiday falls on a Saturday, the majority of the time, the market will close on the preceding Friday. If the holiday falls on a Sunday, the market will be closed the following Monday. For example, since Independence Day (July 4) falls on a Saturday in 2026, the NYSE and Nasdaq will be closed on Friday, July 3, in observance of the holiday.Extended trading hours and risksWhile regular trading hours for the US market are from 9:30 a.m. to 4:00 p.m. ET, extended hours trading, including pre-market and after-hours trading, are also available. Pre-market hours start from 4:00 a.m to 9:30 a.m. ET. After-hours trading is from 4:00 p.m. to 8:00 p.m. ET. However, trading in these extended periods often attracts lower liquidity and higher volatility, which can result in less ideal pricing for transactions. The availability of extended hours trading may also vary depending on the broker.Why these holidays matter to investorsThese holidays are important for investors as:No trading and liquidity impactOn market holidays in the US, there is no price discovery in US equities and ETFs. Global markets that remain open may still react to overnight news, which can lead to gap openings when US markets reopen.Settlement timelines (T+1)Since the US markets operate on a T+1 settlement cycle, these holidays can cause delays in the settlement for trades placed around those dates. This plays an important role in cash management, margin requirements and cross-border fund transfers.Impact on global markets and IndiaIndian markets often respond to overnight US cues. When US markets close, Indian indices receive fewer global cues, which can reduce volatility or, in some cases, can amplify the market reaction when the markets open after a long weekend.The bottom lineUS stock market holidays are observed globally by brokers and investors tracking major U.S. stock exchanges like the New York Stock Exchange (NYSE) and Nasdaq. Beyond standard weekend closures, the exchanges follow a fixed list of annual holidays on which there are no trading activities. For global investors, including those in India, tracking these holidays is important to prevent execution problems, to manage settlements and to anticipate the effects of global cues on Indian markets when trading resumes.
