The summit of the entire Liturgical Year is the Sacred Easter Triduum -- from the evening of Holy Thursday to Easter Sunday. Although it takes place over three days, it is liturgically one day - the unfolding of the unity of Christ's Paschal Mystery.
To receive the fullness of the graces, please make it a point to come and celebrate as the last three days of Jesus' life on earth are recounted.
*Please note this revised schedule includes Veneration of the Cross on Good Friday.
