Holy Saturday i.e. the Saturday of Holy Week, also known as the Great Sabbath, Black Saturday, or Easter Eve, and called "Joyous Saturday" or "the Saturday of Light" among Coptic Christians, is the day after Good Friday. It is the day before Easter and the last day of  Holy Week in which Christians prepare for Easter. It commemorates the day that Jesus Christ's body lay in the tomb and the Harrowing of Hell.
