Advent is a season observed in many Western Christian churches as a time of expectant waiting and preparation for the celebration of the Nativity of Jesus at Christmas. The term is an anglicized version of the Latin word adventus, meaning “coming”.
Latin adventus is the translation of the Greek word parousia, commonly used to refer to the Second Coming of Christ. For Christians, the season of Advent anticipates the coming of Christ from two different perspectives. The season offers the opportunity to share in the ancient longing for the coming of the Messiah, and to be alert for his Second Coming.
Advent is the beginning of the Western liturgical year and commences on Advent Sunday. At least in the Roman Catholic, Anglican, Lutheran, Moravian, Presbyterian and Methodist calendars, Advent starts on the fourth Sunday before December 25, which is the Sunday between November 27 and December 3 inclusive.
