How to Calculate US Stock Market Closing Time? The Complete Trading Hours Guide for Taiwanese Investors

Key Tip: The United States entered Standard Time at 2:00 AM on November 2, 2025. Currently, regular US stock trading hours in Taiwan local time are from 22:30 to 5:00 the next day.

1. Why is the US stock market closing time so important?

For Taiwanese investors, understanding the US stock market closing time is the first step to successful trading. The US stock market operates independently across three major exchanges. Although trading hours are mostly synchronized, opening, closing, and price times may vary slightly between exchanges. Knowing these time differences helps avoid missing trading opportunities or suffering losses due to time zone confusion.

2. Quick reference table for US stock closing time and trading sessions

US stocks are based on Eastern Time in the US, with three trading sessions. Here is the latest time conversion table:

Note: The regular trading session is the main trading period before the US stock market closes and is also when most retail investors are most active.

3. Standard Time vs. Daylight Saving Time: Common pitfalls for Taiwanese investors

The US adjusts clocks annually, while Taiwan remains unchanged year-round. This causes a one-hour time difference in US stock market closing times in Taiwan.

Time change rules:

• Daylight Saving Time (DST): Starts at 2:00 AM on the second Sunday in March, ends at 2:00 AM on the first Sunday in November, clocks move forward 1 hour.
• Standard Time: Starts at 2:00 AM on the first Sunday in November, ends at 2:00 AM on the second Sunday in March, clocks move back 1 hour.

Many states adjust according to local regulations. A simple way to remember: During DST, Taiwan’s trading hours are one hour earlier; during Standard Time, one hour later.
