Christmas or Christmas Day is an annual Christian holiday commemorating the birth of Jesus Christ.In 2018 it is celebrated on December 25. Christmas is central to the Christmas and holiday season, and in Christianity marks the beginning of the larger season of Christmastide, which lasts twelve days.
Although a Christian holiday, Christmas is also widely celebrated by many non-Christians, and some of its popular celebratory customs have pre-Christian or secular themes and origins. Popular modern customs of the holiday include gift-giving, music, an exchange of greeting cards, church celebrations, a special meal, and the display of various decorations; including Christmas trees, lights, garlands, mistletoe, nativity scenes, and holly. In addition, Father Christmas (known as Santa Claus in some areas, including North America, Australia and Ireland) is a popular folklore figure in many countries, associated with the bringing of gifts for children.
Because gift-giving and many other aspects of the Christmas festival involve heightened economic activity among both Christians and non-Christians, the holiday has become a significant event and a key sales period for retailers and businesses. The economic impact of Christmas is a factor that has grown steadily over the past few centuries in many regions of the world. (From: Wikipedia, license: CCA-SA)
