There are several theories about the origins of black Friday, one of which is when a black man goes to a long line at the mall on the Friday after Thanksgiving.One popular theory is that since it is the first day after Thanksgiving (the fourth Thursday in November), followed by the traditional big Christmas in the United States, people usually start their Christmas shopping, and many stores are flooded with customers to make big purchases.Traditionally, different colors of ink have been used for accounting. Red means deficit, and black means profit. So let's call this Friday black Friday, and let's call this Friday black Friday. Since store sales usually begin at midnight (Friday zero), the day after Thanksgiving, bargain hunters have to line up at the mall in the dark, which can also be seen as a black Friday tradition.This behavior has a very figurative name, Early Bird.
November and December are the traditional shopping season in the United States, and black Friday is the wildest shopping day of the year in the United States.Store employees use the name black Friday to mock themselves, saying it's a busy day.
