In Western Christianity, Advent begins on the fourth Sunday prior to Christmas Day, or the Sunday which falls closest to November 30, and lasts through Christmas Eve, or December 24. When Christmas Eve falls on a Sunday, it is the last, or fourth Sunday of Advent.
In Eastern Orthodox churches which use the Julian calendar, Advent begins earlier, on November 15, and lasts 40 days, rather than 4 weeks.
