Triduum (from Latin, meaning "the three days") is the three-day period that begins with the Evening of Holy Thursday Liturgy and ends with Easter Sunday Evening Prayer. It unfolds the Paschal Mystery from the Passion, Crucifixion, Death, Burial, and Resurrection of Christ. Observance of the Triduum ushers in the end of the Lenten season, leading us in hopeful anticipation to the Mass of the Resurrection of the Lord at Easter Vigil.
