What is Black Friday?

Black Friday usually refers either to the infamous Wall Street Panic of September 24, 1869, when Jay Gould and James Fisk tried to corner the gold market, or to September 19, 1873, when stock failures caused the Panic of 1873.

Shoppers and retailers in the United States, and nowadays in many parts of the world, also refer to the day after Thanksgiving as Black Friday because it marks the beginning of the Christmas commercial season and is traditionally a frenetic day of shopping.
