Under normal circumstances, the New York Stock Exchange (NYSE) schedule is from Monday through Friday 9:30 a.m. to 4:00 p.m. ET. NYSE Arca is also open from 4:00 a.m. to 9:30 a.m. ET and 4:00 p.m. to 8:00 p.m.
Most U.S. stock exchanges follow the NYSE holiday calendar in regard to days when the market is closed or observing abbreviated hours. The NYSE and its affiliated exchanges (NYSE MKT, NYSE Amex Options, NYSE Arca, NYSE Arca Options, and NYSE Bonds) close for official U.S. holidays.
Although NYSE Arca follows the same holiday calendar as the NYSE, on days when the NYSE closes early, NYSE Arca hours may vary due to its extended trading day.
In addition to the days noted on the NYSE holiday calendar, the markets sometimes also close for special occasions or emergencies.

Regarding Washington's Birthday: First declared a federal holiday by an 1879 act of Congress. The Monday Holiday Law, enacted in 1968, shifted the date of the commemoration of Washington's Birthday from February 22 to the third Monday in February, but neither that law nor any subsequent law changed the name of the holiday from Washington's Birthday to President's Day. Although the third Monday in February has become popularly known as President's Day, the NYSE's designation of Washington's Birthday as an Exchange holiday (Rule 51) follows the form of other federal holidays.
