Black Friday is the day following Thanksgiving Day in the United States (the fourth Thursday of November).
Since the early 2000s, it has been regarded as the beginning of the Christmas shopping season in the US.
Many non-retail employees and schools have both Thanksgiving and the following Friday off in the US.
The day’s name originated in Philadelphia, where it originally was used to describe the heavy and disruptive pedestrian and vehicle traffic that would occur on the day after Thanksgiving.
Later, an alternative explanation was made: that retailers traditionally operated at a financial loss (‘in the red’) from January through November, and ‘Black Friday’ indicates the point at which retailers begin to turn a profit.
