Good Friday is a significant day in the Christian calendar that commemorates the crucifixion of Jesus Christ. It is observed during Holy Week on the Friday before Easter Sunday and is a time of solemn reflection, mourning, and remembrance of the sacrifice Jesus made for humanity's sins.
The term "Good Friday" is thought to have originated from the Old English word "good," which at the time meant "holy" or "pious." Thus, it signifies a "holy" day rather than implying that the day itself is "good" in a conventional sense.
