good friday

Good Friday, also called Holy Friday, Great Friday or Black Friday, is a religious holiday observed primarily by adherents to Christianity commemorating the crucifixion of Jesus and his death at Golgotha, an event central to Christian theology. 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 of the Sanhedrin Trial of Jesus, the Crucifixion of Jesus was most probably on a Friday. The exact year of Good Friday has been estimated as 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.
