Black Friday is the day after the American holiday of Thanksgiving, which is celebrated on the fourth Thursday of November. It traditionally marks the start of the holiday shopping season. Retailers often offer significant sales and discounts on Black Friday to attract customers, leading to a surge in shopping activity. It’s called “Black Friday” because it’s historically the day when retailers begin to turn a profit, or “go into the black,” for the year. In recent years, Black Friday has expanded beyond a single day and often includes the entire weekend following Thanksgiving, as well as online sales that can start as early as the week of Thanksgiving.
