Friday, November 29 is Black Friday 2019.
In retail and online shopping the first day after Thanksgiving in the United States is referred to as Black Friday. Black Friday is generally perceived to be one of the largest major U.S. holiday shopping days for the retail industry, and is the day that most retailers become profitable for the year (i.e., go into the black). Black Friday is more associated with brick-and-mortar retail stores than online stores.
