The day when Christians each year commemorate the crucifixion of Jesus. There was for a long time no special annual observance of the crucifixion of Jesus except that from the 2nd cent. every Friday was a day of fasting. The death and resurrection were commemorated in a single Paschal festival over Saturday and Sunday. But in the 4th cent. there was a development of Holy Week at Jerusalem in which the historical events of the passion were rehearsed, and then Good Friday became a distinct occasion for recalling the Crucifixion, and Easter Sunday for celebrating the Resurrection. Only the latter allowed the adjective ‘good’ to be applied to the Friday.
