Good Friday is a Christian religious holiday commemorating the crucifixion of Jesus Christ and his death at Calvary. The holiday is observed during Holy Week as part of the Paschal Triduum on the Friday preceding Easter Sunday, and may coincide with the Jewish observance of Passover. It is also known as Holy Friday, Great Friday, Black Friday, or Easter Friday, though the last term properly refers to the Friday in Easter week.
Easter, also called Pasch or Resurrection Sunday, is a festival and holiday celebrating the resurrection of Jesus Christ from the dead, described in the New Testament as having occurred on the third day of his burial after his crucifixion by Romans at Calvary c. 30 AD. It is the culmination of the Passion of Christ, preceded by Lent, a forty-day period of fasting, prayer, and penance.
