What is the common name for the day after Thanksgiving known for shopping sales?

The common name for the day after Thanksgiving known for shopping sales is Black Friday.

In the United States, Black Friday falls on the Friday after Thanksgiving and traditionally marks the unofficial beginning of the Christmas shopping season. Retailers promote heavily discounted items, limited-time offers, and “doorbuster” deals to attract large crowds. It is a commercial observance, not a federal holiday, although some employers, schools, and state governments give people the day off.

The term has older meanings, including the financial panic of 1869. Its retail meaning emerged in the mid-20th century, especially in Philadelphia, where police used it for the traffic and crowds created by shoppers. The popular explanation that stores move from “the red” into “the black” later helped make the name more appealing.

Black Friday is often confused with Cyber Monday, which is the following Monday and emphasizes online shopping. Small Business Saturday comes the next day, on Saturday.
