All Saints' Day

All Saints' Day, also known as All Hallows, Day of All the Saints, Solemnity of All Saints, or Feast of All Saints is a festival celebrated on 1 November by the Latin Church of the Roman Catholic Church and some other Western Christian traditions, and on the first Sunday after Pentecost in Eastern Catholicism and Eastern Orthodoxy, in honour of all the saints, known and unknown. The liturgical celebration begins at Vespers on the evening of 31 October and ends at the close of 1 November. It is thus the day before All Souls' Day.
