The next upcoming Holy Saturday is on Saturday March 30th, 2024.
All Masses for the day are limited to Baptism, Penance, and anointing of the sick to provide salvation, with many churches stripping the chancel bare and other churches covering the alter in black. Holy Saturday lasts till 6pm and then Easter Vigil is celebrated in the churches with the lighting of the paschal candle bringing in the start of the Easter celebrations.
Holy Saturday has many names including Great Sabbath, Black Saturday, and Easter Eve. This day marks the last day of Holy week and the end of the roughly six week period of Lent that started on Ash Wednesday.
