2025 US Stock Trading Complete Guide: Holiday and Trading Hours Schedule at a Glance

Introduction: Essential Knowledge for U.S. Stock Investors

Trading U.S. stocks involves more than just selecting the right stocks. If you do not accurately understand trading hours, holidays, and time zone differences, you may miss trading opportunities or incur unexpected losses. Especially since there is over a 13-hour time difference with Korea, and during daylight saving time in the U.S., trading hours change, so caution is required. Additionally, unlike Korea, the U.S. stock market has no price limit bands, making rapid responses during sharp declines more difficult, which should not be overlooked.

This article summarizes the exact trading hours of the New York Stock Exchange, NASDAQ, and American Stock Exchange, as well as the U.S. stock market holidays in 2025, providing a comparison table based on Korea time. You can also compare with major global stock markets.
