Black Friday
   Black Friday is the day following Thanksgiving Day in the United States, often regarded as the beginning of the Christmas shopping season. In recent years, most major retailers have opened extremely early and offered 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 employees and schools have both Thanksgiving and the day after off, followed by a weekend, 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.
   The day’s name originated in Philadelphia, where it originally was used to describe the heavy and disruptive pedestrian and vehicle traffic which would occur on the day after Thanksgiving. Use of the term started before 1961 and began to see broader use outside Philadelphia around 1975. Later an alternative explanation began to be offered: that "Black Friday" indicates the point at which retailers begin to turn a profit, or are "in the black".
   For many years, it was common for retailers to open at 6: 00 a. m. , but in the late 2000s many opened at 5: 00 or even 4: 00 in the morning. This was taken to a new extreme in 2011, when several retailers opened at midnight for the first time. This year, Walmart and several other retailers announced that they would open most of their stores at 8:00 p. m. on Thanksgiving Day (except in states where opening on Thanksgiving is prohibited due to blue laws, such as Massachusetts where they still opened around midnight, prompting calls for a walkout among some workers.
