- The origins of Easter are rooted in Christianity and the biblical accounts of Jesus Christ's crucifixion and resurrection, which took place during the Jewish festival of Passover. Early Christians would commemorate Jesus's death and resurrection on Sundays and eventually designated a specific Sunday each year to celebrate Easter.
- In the early 4th century, Easter was celebrated through liturgical rites that renewed the sacrifice of Jesus's body and blood. Over time, Holy Week developed as a way to relive the mysteries of Christ through Palm Sunday, Holy Thursday, Good Friday, and Holy Saturday, culminating in the celebration of Easter Sunday.
