Black Friday is the name given to the day following Thanksgiving Day in the United States, traditionally the beginning of the Christmas shopping season. On this day, most major retailers open extremely early, often at 4 am, or earlier, and offer promotional sales to kick off the holiday shopping season, similar to Boxing Day sales in many Commonwealth Nations. Black Friday is not an official holiday, but many non-retail employers also observe this day as a holiday along with Thanksgiving, giving their employees the day off, thereby increasing the number of potential shoppers. It has routinely been the busiest shopping day of the year since 2005, although news reports, which at that time were inaccurate, have described it as the busiest shopping day of the year for a much longer period of time.
