The week immediately preceding Easter or Resurrection Sunday. It is observed in many Christian churches as a time to commemorate and enact the suffering (Passion) and death of Jesus through various observances and services of worship. While some church traditions focus specifically on the events of the last week of Jesus’ life, many of the liturgies symbolize larger themes that marked Jesus’ entire ministry. Observances during this week range from daily liturgical services in churches to informal meetings in homes to participate in a Christian version of the Passover Seder.
