Good Friday, also known as Holy Friday, Great Friday, Great and Holy Friday, or Friday of the Passion of the Lord, is a solemn Christian holy day commemorating the crucifixion of Jesus and his death at Calvary (Golgotha). It is observed during Holy Week as part of the Paschal Triduum.
The date of Good Friday varies from one year to the next in both the Gregorian and Julian calendars. Eastern and Western Christianity disagree over the computation of the date of Easter and therefore of Good Friday. Good Friday is a widely instituted legal holiday around the world. Some predominantly Christian countries, such as Germany, have laws prohibiting certain acts—public dancing, horse racing—in remembrance of the sombre nature of Good Friday.
