Brief Bio

All Saints' Day, also known as All Hallows' Day, the Feast of All Saints, the Feast of All Hallows, the Solemnity of All Saints, and Hallowmas, is a Christian solemnity celebrated in honour of all the saints of the Church, whether they are known or unknown.

From the 4th century, feasts commemorating all Christian martyrs were held in various places, on various dates near Easter and Pentecost. In the 9th century, some churches in the British Isles began holding the commemoration of all saints on 1 November, and in the 9th century this was extended to the whole Catholic Church by Pope Gregory IV.

In Western Christianity, it is still celebrated on 1 November by the Western Catholic Church as well as by many Protestant churches, such as the Lutheran, Anglican, and Methodist traditions. The Eastern Orthodox Church and associated Eastern Catholic and Eastern Lutheran churches celebrate it on the first Sunday after Pentecost. The Syro-Malabar Church and the Chaldean Catholic Church, both of which are in communion with Rome, as well as the Church of the East, celebrate All Saints' Day on the first Friday after Easter Sunday. In the Coptic Orthodox tradition, All Saints' Day is on Nayrouz, celebrated on 11 September. The day is the start of the Coptic new year, and of its first month, Thout.
