Among Christian beliefs, the death and resurrection of Jesus are two main events of Christian doctrine and theology. From what the New Testament says, Jesus was crucified, died a physical death, was buried in a tomb, and rose from the dead on the third day afterwards. Most Christians place his death on a Friday each year, which is the first day of his death. Saturday is the second day, and Sunday is the third day. The New Testament writes that after rising from the dead Jesus appeared many times before his Twelve Apostles and disciples. Once He appeared before "more than five hundred brethren at once". This was before Jesus' Ascension to heaven. Jesus' death and resurrection are remembered by Christians in their worship services, and most commonly during Holy Week, which has Good Friday and Easter Sunday in the week.
