Holy Thursday / Maundy Thursday / Great Thursday (Christian)
The Thursday before Easter, commemorates Christ’s Last Supper with the Apostles.
On this day four events are commemorated: the washing of the Disciples’ feet by Jesus Christ, the institution of the Mystery of the Holy Eucharist at the Last Supper, the agony of Christ in the Garden of Gethsemane, and the betrayal of Christ by Judas.*
