Triduo Pascual
Maundy Thursday initiates the Paschal Triduum, the period which commemorates the passion, death, and resurrection of Jesus; this period includes Good Friday and Holy Saturday, and ends on the evening of Easter Sunday. The Mass of the Lord's Supper or service of worship is normally celebrated in the evening, when Friday begins according to Jewish tradition, as the Last Supper was held on the feast of Passover, according to the three Synoptic Gospels.
