Stock Market Hours and Holidays: NYSE and Nasdaq Guide

If you are asking whether the stock market is open today, the answer depends on the exchange session and the holiday calendar. NYSE and Nasdaq share the same standard equity trading schedule, but pre-market, after-hours, early closes, and bond-market holidays can make the answer different from one market to another.

What are the regular NYSE and Nasdaq trading hours?

The main U.S. stock market session for NYSE- and Nasdaq-listed shares runs on the same weekday schedule. This is the session most retail investors mean when they ask about stock market hours, and it is the benchmark used by most brokers and market data services. If you want a broader glossary of market terms, see our market glossary.

During the regular session, orders are matched in the primary market, spreads are usually tighter than in off-hours trading, and trading volume is typically highest. Many orders entered outside the session may queue for the next open unless the broker routes them to an extended-hours venue.

How do pre-market and after-hours sessions work?

Pre-market and after-hours trading are extended-hours sessions that let investors react to news before or after the regular session. Availability depends on the broker, the security, and the order type. Not every stock is equally liquid in these sessions, and prices can move more sharply because fewer participants are active.

Extended-hours trading is useful for price discovery, but it also carries extra risk. Quotes may be wider, executions may be partial, and market orders can be less predictable than during the regular session.

When do early closes happen?

Some holiday periods end with a shortened trading day rather than a full closure. In U.S. equities, the best-known early close is the session before Thanksgiving, when trading ends ahead of the usual close. Exchanges may also announce other shortened sessions for special circumstances, so the practical rule is to check the exchange notice before assuming the market will stay open the full day.

On early-close days, the morning and midday sessions can trade normally, but liquidity may thin out faster as the shortened close approaches. Settlement timing, broker cutoff times, and order expirations can also differ from a standard day.

Which holidays close the stock market?

The major U.S. equity exchanges generally close for a fixed set of holidays each year. When a holiday falls on a weekend, the closure is usually observed on the nearest weekday according to exchange rules, which means the market may close on a Friday or Monday instead of the calendar holiday itself.

Christmas	Closed	Observed on a weekday when needed	Observed market holiday rule

How are weekend holidays observed?

When a market holiday lands on a Saturday or Sunday, the exchange normally observes it on a nearby weekday. That is why a holiday can affect trading on the preceding Friday or the following Monday even though the calendar holiday itself is on the weekend. The exact observation rule matters for order scheduling, account funding, and any plan to trade around a long weekend.

The safest approach is to treat the exchange calendar, not the civil calendar, as the final word. A broker may show the market as closed on the observed day even if the holiday name appears to belong to the weekend date.

How do bond-market holidays differ from stock-market holidays?

Bond markets do not always follow the same closure pattern as equities. Some holidays are full closures for both, while others can be partial or shorter sessions for bonds even when stocks are open. That makes fixed-income trading calendars a separate reference point, not a simple copy of equity market hours.

For example, the municipal and Treasury bond markets may observe different schedules from NYSE and Nasdaq, and trading desks often use separate holiday calendars for each segment. If you trade both stocks and bonds, compare the exchange calendar with your broker's fixed-income schedule and any market-specific notices before assuming both markets follow the same rules.

What should investors check before placing an order?

Before entering an order, confirm three things: whether the regular session is open, whether the market is in an extended-hours period, and whether the day is a holiday or early close. These details can affect execution quality, available order types, and the time your trade actually reaches the market.

If you need a quick practical check, use the exchange calendar, your broker's trading-hours page, and any notices about maintenance or special sessions. For planning tools and reference material, our tools section can help you organize the schedule before the market opens.
