The term 'Period Before Christmas' is often referred to as ADVENT. ADVENT is a season observed in many Christian churches as a time of expectant waiting and preparation for the celebration of the Nativity of Jesus at Christmas. It is a time of spiritual preparation in which believers reflect on their relationship with God and prepare for the coming of Jesus. The season of ADVENT typically begins four Sundays before Christmas Day, or the Sunday nearest November 30, and ends on Christmas Eve.
