There are many theories about the origin of "Black Friday". One of them is that on the Friday after Thanksgiving, a group of people in the dark lined up at the mall to shop. A common view is that since this day is the first day after Thanksgiving (165438+1the fourth Thursday in October), it is followed by the traditional and grand Christmas in the United States, people usually start Christmas shopping here, and many stores will be crowded with customers, thus earning a lot of income. Traditionally, different colors of ink are used for bookkeeping, with red indicating loss or deficit and black indicating profit. Therefore, this Friday is called Black Friday to show that this day is expected to be profitable. Because store discounts usually start at midnight after Thanksgiving (that is, at 0: 00 on Friday), people who want to buy bargains have to rush to the mall to buy bargains in the dark, which can also be regarded as the origin of "Black Friday". This kind of behavior has a very vivid saying, called Early Bird. 165438+ 10 and 65438+February are the traditional shopping seasons in the United States, and "Black Friday" is the craziest shopping day for Americans in a year. The employees in the store laughed at themselves with the name Black Friday, saying it would be a busy day.
