Good Friday, also called
Holy Friday, Black Friday, or
Great Friday, is a
holiday observed primarily by adherents to
Christianity commemorating the
crucifixion of Jesus 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 often coincides with the Jewish observance of
Passover.
Based on the scriptural details[citation needed] of the Sanhedrin Trial of Jesus, the Crucifixion of Jesus was most probably on a Friday. The estimated year of Good Friday is AD 33, by two different groups, and originally as AD 34 by Isaac Newton via the differences between the Biblical and Julian calendars and the crescent of the moon.[1][2][3][4][5][6] A third method, using a completely different astronomical approach based on a lunar Crucifixion darkness and eclipse model (consistent with Apostle Peter's reference to a "moon of blood" in Acts 220) arrives at the same date, namely Friday April 3, AD 33.[7][8]
According to the accounts in the Gospels, Jesus was arrested in the Garden of Gethsemane by the Temple Guards through the guidance of his disciple, Judas Iscariot. Judas received money (30 pieces of silver) (Matthew 2614-16) for betraying Jesus and told the guards that whomever he kisses is the one they are to arrest. Jesus is brought to the house of Annas, who is the father-in-law of the current high priest, Caiaphas. There he is interrogated with little result, and sent bound to Caiaphas the high priest, where the Sanhedrin had assembled (John 181-24).
Conflicting testimony against Jesus is brought forth by many witnesses, to which Jesus answers nothing. Finally the high priest adjures Jesus to respond under solemn oath, saying "I adjure you, by the Living God, to tell us, are you the Anointed One, the Son of God?" Jesus testifies in the affirmative, "You have said it, and in time you will see the Son of Man seated at the right hand of the Almighty, coming on the clouds of Heaven." The high priest condemns Jesus for blasphemy, and the Sanhedrin Trial of Jesus concurs with a sentence of death (Matthew 2657-66). Peter also denies Jesus three times during the interrogations. Jesus already knew that Peter would deny him three times. See the article Sanhedrin Trial of Jesus regarding the two trials, one at night, the other in the morning and how their timing may affect the day of Good Friday.
