The Friday before Easter — Christian commemoration of the crucifixion of Jesus.
Astronomically anchored to Easter (the first Sunday after the first full moon following the spring equinox in the Western tradition). The date is the same globally each year, though Eastern Orthodox traditions use a different rule.
Good Friday marks the crucifixion and death of Jesus Christ at Calvary. It is observed with solemnity — fasting, prayer, and church services that retrace the Stations of the Cross. The date moves with Easter; it is always the Friday immediately preceding Easter Sunday.
Computed for Delphi (Europe/Athens) using local sunrise, sunset and astronomical positions.
