Advent is a word that is not often used by Orthodox Christians living in the East parts of the world. It is used more frequently by Orthodox Christians living in the West, for the simple reason that when they say “Advent”, other Christians immediately understand they are referring to a period of preparation before the Great Feast of Christmas, the Nativity of our Lord.
There are three key differences between Orthodox and Western Advent:
1. Advent in Western Christianity begins on the fourth Sunday before Christmas, while in the Orthodox Church it begins forty days before Christmas (November 15).
2. Western Advent is focused on both the First and Second Comings of Christ, whereas the primary focus of Orthodox Advent is the Incarnation of our Lord.
3. Advent Sunday marks the beginning of the liturgical year in the Western churches, while the ecclesiastical year of the Orthodox Church begins on September 1.
