Easter, also known as Resurrection Sunday, is on April 20, 2014. Jesus was crucified on Good Friday, and rose from the dead after three days. Through his death, burial, and resurrection, Jesus paid the penalty for sin, thus for all who believe in him will have eternal life in Heaven.
Easter Sunday is preceded by Holy Week, it marks the important events of Jesus' life as described in the four book of Gospels -- his triumphal entrance to Jerusalem on Palm Sunday, the Last Supper on Maundy Thursday, and his death and crucifixion on Good Friday.
Before the celebration of resurrection on Easter, Christians remember the sacrifice and love of Jesus on the cross.

In Jerusalem, the holy fire ceremony draws tens of thousands of Orthodox Christians on April 19. Christians believe Jesus was crucified, buried and resurrected at the site where the Church of the Holy Sepulcher now stands in the Old City of Jerusalem.
