Все вокруг кричат о предложениях к Чёрной пятнице. Что ж это за пятница такая?

Black Friday is an informal name for the Friday following Thanksgiving Day in the United States, which is celebrated on the fourth Thursday of November. Black Friday has been regarded as the beginning of America's Christmas shopping season since 1952, although the term "Black Friday" didn't become widely used until more recent decades.

Many stores offer highly promoted sales on Black Friday and open very early, such as at midnight, or may even start their sales at some time on Thanksgiving. Black Friday is not an official holiday, but California and some other states observe "The Day After Thanksgiving" as a holiday for state government employees, sometimes in lieu of another federal holiday, such as Columbus Day. Many non-retail employees and schools have both Thanksgiving and the following Friday off, which, along with the following regular weekend, makes it a four-day weekend, thereby increasing the number of potential shoppers.
