Stock trading will be closed in the U.S. in observance of Good Friday this week.

Good Friday is an exception to other stock market holidays in the U.S. such as Thanksgiving and Christmas because it is not also a federal holiday. That means the government and many businesses will be open.

Nonetheless, stock trading has traditionally closed for the day, with some exceptions.

The New York Stock Exchange, which opened for business in 1817, first shut down trading for Good Friday in 1864, according to the NYSE. The Christian holy day marks the crucifixion of Jesus and precedes Easter.

Since then, the exchange has closed on Good Friday every year but three: 1898, 1906 and 1907, the NYSE said.

Not all trading in U.S. financial markets comes to a halt on Good Friday.

Bond trading will be open until 12 p.m. Eastern time, and electronic trading on the Chicago Mercantile Exchange will be open briefly, giving investors a window until 10:30 Eastern time to trade futures for the S&P 500 stock index and other financial instruments.

Good Friday is one of nine stock market holidays in the U.S. The others are New Year's Day, Martin Luther King Jr.'s birthday, Washington's Birthday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas.
