Why is it called Black Friday? What is its origin?

Because on the fourth Friday of 1 1 month (the second day of Thanksgiving), the accounts used by merchants to record profits are all black, so it is called Black Friday.

American businessmen will choose black and red ink when keeping accounts. Red ink means loss, and black ink means profit. After Thanksgiving, the demand for all kinds of goods has increased greatly, and businesses have earned a lot of money, with a piece of black ink on their accounts. Therefore, westerners will call such a crazy shopping day "Black Friday".

Just like the double eleven in our country, there is no such thing as bad luck. Black here means that the business has too much profit and the accounts are all black.

Extended data:

Two other expressions of Black Friday:

The first refers to a group of dark people who line up in shopping malls on Friday after Thanksgiving. Traditionally, they use different colors of ink to keep accounts, 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.

Another way to put it, the discount activities in stores usually start at midnight after Thanksgiving (that is, at 0: 00 on Friday). On the second day after Thanksgiving, people who want to buy bargains have to queue up at the mall in the dark to buy bargains, which can also be regarded as the origin of "Black Friday".
