Paschal Triduum
The Paschal Triduum or Easter Triduum (Latin: "Triduum Paschale"), Holy Triduum (Latin: "Triduum Sacrum"), or the Three Days, is the period of three days that begins with the liturgy on the evening of Maundy Thursday, reaches its high point in the Easter Vigil, and closes with evening prayer on Easter Sunday. It is a moveable observance recalling the Passion, Crucifixion, Death, burial, and Resurrection of Jesus, as portrayed in the canonical Gospels.
