Holy Saturday (Latin: Sabbatum Sanctum), sometimes known as Easter Eve^[1] or Black Saturday, 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 laid in the tomb.

Holy Saturday is sometimes called Easter Saturday,^[2] though this phrase is more correctly applied to the Saturday in Easter Week.^[3]

Good Friday (from the senses pious, holy of the word "good"),^[1] is a religious holiday observed primarily by Christians commemorating the crucifixion of Jesus Christ and his death at Calvary. The holiday is observed during Holy Week as part of the Paschal Triduum on the Friday preceding Easter Sunday, and may coincide with the Jewish observance of Passover. It is also known as Holy Friday, Great Friday, Black Friday,^[2] or Easter Friday,^[3] though the latter properly refers to the Friday in Easter week.
