This one is for my oldest son. My eleven year old asked me earlier this week where the term Black Friday came from. Black Friday is the day after Christmas. The phrase is believed to have originated in the Philadelphia area. It is the first day of the Christmas shopping season. The day is famous, or infamous if you prefer, for its retail sales which are very hectic and cause a lot of traffic. The widespread chaos is meant to refer to Black Tuesday of the stock market crash of 1929. Some people understand the term to be an Accounting term meaning the point in the year where businesses begin turning a profit, hopefully coming out of the red (referring to an accounting term) into the black. It is highly unlikely this meaning is correct, because as far back as research goes the phrase has always been associated with traffic and crowds.
