"The three-day celebration begins with the Holy Thursday Mass and continues on Good Friday with the Liturgy of the Lord’s Passion. At the end of this liturgy, we leave the church in silence, waiting to celebrate the glory of our Lord’s resurrection. Then, on Saturday at sundown, the Church re-gathers to celebrate the final, and most grand moment of the Triduum: the Resurrection of our Lord."

Palm branches:

"Holy Week begins on the Sunday before Easter, known as Palm Sunday. Palm Sunday is named after the palm branches the Jews used to praise Jesus as he entered Jerusalem at the start of his Passion. Palms were an important symbol in Jewish history.

Purple veils on statues:

“During Holy Week churches cover crosses, statues, and other sacred depictions with purple veils. This veiling of sacred items reminds us that, without Jesus’ ultimate sacrifice and glorious Resurrection, our faith and everything sacred related to it wouldn’t exist.”

Bread and Wine:

Among the most poignant symbols of Holy Week are the bread and wine. These images recall Jesus’ institution of the Holy Eucharist at the Last Supper on the day before his crucifixion. During that Passover meal, Jesus offered himself as the sacrificial lamb by transforming bread and wine into his own Body and Blood.”
