All Saints’ Day, also known as All Hallows’ Day, Hallowmas, the Feast of All Saints, or Solemnity of All Saints,is a Christian festival celebrated in honour of all the saints, known and unknown. In Western Christianity, it is celebrated on November 1 by the Roman Catholic Church, the Anglican Communion, the Methodist Church, the Lutheran Church, the Reformed Church, and other Protestant churches. The Eastern Orthodox Church and associated Eastern Catholic Churches and Byzantine Lutheran Churches celebrate it on the first Sunday after Pentecost.^[8] Oriental Orthodox churches of Chaldea and associated Eastern Catholic churches celebrate All Saints’ Day on the first Friday after Easter.

In the Western Christian practice, the liturgical celebration begins at Vespers on the evening of 31 October, All Hallows’ Eve (All Saints’ Eve), and ends at the close of 1 November. It is thus the day before All Souls’ Day, which commemorates the faithful departed. In many traditions, All Saints’ Day is part of the season of Allhallowtide, which includes the three days from 31 October to 2 November inclusive and in some denominations, such as Anglicanism, extends to Remembrance Sunday. On All Saints Day, it is common for families to attend church, as well as visit cemeteries in order to lay flowers and candles on the graves of their deceased loved ones. It is a national holiday in many historically Christian countries.
