 While in other countries the only holidays included in the "season" are Christmas Eve, Christmas Day, St. Stephen's Day/Boxing Day, New Year's Eve, New Year's Day and Epiphany, in recent times, this definition in the U.S. has begun to expand to include Yule, Hanukkah, Kwanzaa, Thanksgiving, Black Friday and Cyber Monday.The expansion of the holiday season in the U.S. to encompass Thanksgiving is believed to have begun in the 1920s, when in major department stores Macy's and Gimbels were launched dueling Thanksgiving Day parades to promote Christmas sales.Due to the phenomenon of Christmas creep and the informal inclusion of Thanksgiving, the Christmas and holiday season has begun to extend earlier into the year, overlapping Veterans/Remembrance/Armistice Day, Halloween and Guy Fawkes Night.
