The Church's liturgical year is made up of six seasons:
Advent - four weeks of preparation before the celebration of Jesus' birth
Christmas - recalling the Nativity of Jesus Christ and his manifestation to the peoples of the world
Lent - a six-week period of penance before Easter
Sacred Paschal Triduum - the holiest "Three Days" of the Church's year, where the Christian people recall the suffering, death, and resurrection of Jesus
Easter - 50 days of joyful celebration of the Lord's resurrection from the dead and his sending forth of the Holy Spirit
