All Saints is a Christian festival celebrated on November 1st each year. It honors all saints, known and unknown, who have attained heaven. The day is significant in many Christian denominations, including Catholicism, Orthodoxy, and some branches of Protestantism. The origins of All Saints date back to the early Christian church, with the first recorded celebration occurring in the 4th century. It is often associated with the Feast of All Saints, which was established to commemorate martyrs and saints who did not have specific feast days.
