Given that it is the day on which Christians remember the crucifixion and death of Jesus Christ, Good Friday is not seen as a "happy day."
It is a gloomy and depressing day of contemplation, lamentation,
and confession for the sins that caused Jesus to suffer and die on the cross.
Christians hold that Jesus gave his life voluntarily to atone for humankind's sins,
and they view his death as an essential component of the redemption narrative.
This does not lessen the agony and sorrow of his suffering and death,
and Good Friday is a day when Christians reflect on the magnitude of Jesus' sacrifice and their own sins.
Therefore, rather than being a day of joy or celebration, Good Friday is a day of melancholy remembering and thought.
