Some interesting information about christmas:
Christmas or Christmas Day is an annual festival commemorating the birth of Jesus Christ, observed most commonly on December 25 as a religious and cultural celebration among billions of people around the world. A feast central to the Christian liturgical year, it is prepared for by the season of Advent or Nativity Fast and is prolonged by the Octave of Christmas and further by the season of Christmastide. Christmas Day is a public holiday in many of the world's nations, is celebrated culturally by a large number of non-Christian people,and is an integral part of the Christmas and holiday season.
The celebratory customs associated in various countries with Christmas have a mix of pre-Christian, Christian, and secular themes and origins.Popular modern customs of the holiday include gift giving, completing an Advent calendar or Advent wreath, Christmas music and caroling, an exchange of Christmas cards, church services, a special meal, and the display of various Christmas decorations, including Christmas trees, Christmas lights, nativity scenes, garlands, wreaths, mistletoe, and holly. In addition, several closely related and often interchangeable figures, known as Santa Claus, Father Christmas, Saint Nicholas, and Christkind, are associated with bringing gifts to children during the Christmas season and have their own body of traditions and lore
For Christians, the more important a doctrinal point of view, was and is the feast of the Resurrection of Christ (Easter). After the Christian community came Greeks (Hellenistic and other peoples), under the influence of Hellenistic traditions and started celebrating Christmas.
The traditional colors of Christmas decorations are red, green, and gold. Red symbolizes the blood of Jesus, which was shed in his crucifixion, while green symbolizes eternal life, and in particular the evergreen tree, which does not lose its leaves in the winter, and gold is the first color associated with Christmas, as one of the three gifts of the Magi, symbolizing royalty.
The Christmas tree is considered by some as Christianisation of pagan tradition and ritual surrounding the Winter Solstice, which included the use of evergreen boughs, and an adaptation of pagan tree worship.
