All Saints day

All Saints' Day (in the Roman Catholic Church officially the Solemnity of All Saints and also called All Hallows or Hallowmas), often shortened to All Saints, is a solemnity celebrated on 1 November by parts of Western Christianity, and on the first Sunday after Pentecost in Eastern Christianity, in honour of all the saints, known and unknown.

In Western Christian theology, the day commemorates all those who have attained the beatific vision in Heaven. It is a national holiday in many historically Catholic countries. In the Roman Catholic Church and many Anglican churches, the next day, All Souls' Day, specifically commemorates the departed faithful who have not yet been purified and reached heaven. Catholics celebrate All Saints' Day and All Souls' Day in the fundamental belief that there is a prayerful spiritual communion between those in the state of grace who have died and are either being purified in purgatory or are in heaven (the 'church penitent' and the 'church triumphant', respectively), and the 'church militant' who are the living. Other Christian traditions define, remember and respond to the saints in different ways; for example, in the Methodist Church, "saints who have helped extend and enliven God's kingdom" are remembered—that is—the entire Church universal and those significant to a particular local congregation.
