Christmas, also known as Christmas, is a Christian festival to commemorate the birth of Jesus. It is scheduled for December 25, and the Orthodox Church calls it Nativity Day. It is an important festival in the Christian liturgical calendar. Some denominations prepare for it through Advent and Christmas Eve, and continue to celebrate it with the eight-day celebration (English: Octave (liturgical)) and the liturgical festival (English: Christmastide). Christmas is also a public holiday in many countries and regions, especially Western countries and other areas where Christian culture is the mainstream; on occasions other than the church, Christmas has been transformed into a folk festival, and is often called "New Year's Day" Christmas and New Year season
