Cyber Monday is a marketing term for the Monday after the Thanksgiving holiday in the United States. The term "Cyber Monday" was created by marketing companies to encourage people to shop online. The term was coined by Ellen Davis and Scott Silverman, and made its debut on November 28, 2005 in a Shop.org press release entitled "'Cyber Monday' Quickly Becoming One of the Biggest Online Shopping Days of the Year". It is on the Monday after Thanksgiving, and most of the time falls in November, but if Thanksgiving is on November 27 or 28, it will fall in December. The date range is November 26 to December 2, and is always four days after the holiday.
Black Friday is a shopping day for a combination of reasons. As the first day after the last major holiday before Christmas, it marks the unofficial beginning of the Christmas shopping season. Additionally, many employers give their employees the day off as part of the Thanksgiving holiday weekend
Christmas is an annual festival commemorating the birth of Jesus Christ, observed primarily on December as a religious and cultural celebration among billions of people around the world. A feast central to the Christian liturgical year, it is preceded by the season of Advent or the Nativity Fast and initiates the season of Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night; in some traditions, Christmastide includes an octave. Christmas Day is a public holiday in many of the world's nations, is celebrated religiously by a majority of Christians, as well as culturally by many non-Christians, and forms an integral part of the holiday season centered around it.
