Black Saturday or Sabado de Gloria in the Philippines is a part of the Holy Week celebration also known as Semana Santa. Observed by the majority Catholic population, it falls between Good Friday and Easter Sunday. This day is a representation of the symbolic waiting for the resurrection of Jesus Christ. It is observed solemnly as a day of silence, reflection, and preparation for the much anticipated joyous event of Easter.

On Black Saturday, a pervasive quietness can be felt throughout the country. Ritual activity ceases in the churches as well, featuring only sparse, undecorated altars. The absence of holy mass, recurring prayers, and biblical narratives marking this day establish a notable change in regular religious practice. Many people choose to spend this day in prayer or in reflection of the Passion of Christ.

Moreover, Black Saturday is also known as an opportunity for families to be together. With the week's observance being declared a nationwide non-working holiday, most Filipinos return to their respective hometowns for family gatherings and reunions. While it’s celebrated within the solemnity of the Holy Week, this day also signifies a brief pause, prior to the climax of celebration on Easter Sunday, when Filipinos participate in 'Salubong' or 'Domingo de Pascua', marking the resurrection of Jesus Christ.
