U.S. daylight saving time runs from the second Sunday in March to the first Sunday in November. Other countries may switch on different dates; check the schedule above.

Why is it Sunday in the U.S. when it is Monday in Korea?

Trading days follow the New York date. For example, Monday's overnight session begins on Sunday evening in New York and Monday morning in Seoul. The schedule shows the actual start date and marks next-day times.

Is overnight trading a regular exchange session?

No. Overnight trading here refers to Blue Ocean ATS (20:00–04:00 ET). Supported stocks, order types and maintenance hours vary by broker. Check availability with your broker.

What changes on an early-close day?

On listed early-close dates, the regular session ends at 13:00 rather than 16:00 ET. The 17:00 ET after-hours close shown here follows NYSE Arca. Other venues and brokers may differ.

Why can't I place an order during scheduled hours?

This schedule shows planned trading hours, not individual halts, broker maintenance, temporary closures or order restrictions. Extended hours may have lower volume and wider spreads.
