When will US stock trading start in 2025? Complete guide to holidays and trading hours

Things You Must Know Before Trading the US Stock Market

If you are planning to buy and sell US stocks, there are essential things you need to know. Specifically, trading hours and market holidays. The US has a significantly different time zone from Korea, and daylight saving time is also applied, so if you don’t know the exact times, you may miss trading opportunities or incur unexpected losses. Additionally, unlike the Korean market, the US stock market has no price limit bands, making it difficult to respond quickly during sharp declines. In this article, I will organize all trading information, including the 2025 US stock market holidays, in a table for your reference.

Overview of the 3 Major US Stock Exchanges

US stock trading mainly occurs on three exchanges.

New York Stock Exchange(NYSE) has been operating since 1792 and is the largest exchange in the world. About 2,400 companies are listed, with a total market capitalization of approximately $23 trillion. Traditional large-cap stocks such as Berkshire Hathaway, Johnson & Johnson, Visa, and Walmart are mainly traded.

Nasdaq(NASDAQ) started in 1971 and is characterized by a focus on technology companies. Stocks like Apple, Microsoft, and Nvidia are traded here, and in terms of market capitalization, it is the second largest in the world after the NYSE.

American Stock Exchange(AMEX) mainly lists mid-sized and small-cap companies, making it popular among investors looking to trade stocks of early-growth-stage companies.

Complete Guide to US Stock Trading Hours

Based on Korea time

All three exchanges operate at the same hours, which are as follows in Korea Standard Time.

Most trading volume is concentrated during regular hours, but trading is also possible during pre-market and after-hours. Keep in mind that liquidity is lower, and bid-ask spreads can be wider.

Check Trading Regulations

All three major US exchanges trade in US dollars(USD), and settlement occurs two business days after the trade. The most notable point is that there are no price limit bands(lock limit) in the US stock market. Unlike Korea, sharp declines can occur in a single trade, so since the market operates at night Korea time, you should prepare risk management strategies accordingly.

2025 US Stock Market Holidays Schedule

The US stock market is closed on national and federal holidays. The holidays for 2025 are as follows.

Check Early Close Dates

Although not holidays, some days see early market close at 1 PM Eastern Time(.

Be Careful with Daylight Saving Time

From the second Sunday in March to the first Sunday in November, daylight saving time is applied in the US. During this period, US Eastern Time is moved one hour ahead, so trading hours in Korea are also effectively one hour earlier. If you don’t adjust your schedule in advance, you may miss trading times, so be cautious.
