Johann Sebastian Bach composed the church cantata Nun komm, der Heiden Heiland, BWV 61, in Weimar for the first Sunday in Advent, the Sunday which begins the liturgical year, and first performed it on 2 December 1714.

Advent is a season observed in most Christian denominations as a time of expectant waiting and preparation for both the celebration of the Nativity of Christ at Christmas and the return of Christ at the Second Coming. Advent is the beginning of the liturgical year in Western Christianity. The name was adopted from Latin adventus "coming; arrival", translating Greek parousia from the New Testament, originally referring to the Second Coming.
