Holy Week is the week preceding Easter and the final week of Lent.
Holy Week begins with Palm Sunday and ends with Holy Saturday, the day before Easter Sunday.
Holy Week includes Holy Thursday (also known as Maundy Thursday) and Good Friday, which, together with Holy Saturday, are known as the Triduum. In the calendar of the Extraordinary Form, Holy Week is the second week of Passiontide.
During Holy Week, Christians commemorate the Passion of Christ, Who died on Good Friday in reparation for the sins of mankind, and rose on Easter Sunday to give new life to all who believe. Thus, while Holy Week is solemn and sorrowful, it also anticipates the joy of Easter through the recognition of God’s goodness in sending His Son to die for our salvation.
