Blessed All Saints Day All Saints’ Day is celebrated on 1 November, to remember and give thanks for all those who have died in the saving faith (the ‘Church Triumphant’) by those still living (the ‘Church Militant’) . All Saints’ Day is the second day of Hallowmas and begins at sunrise on the first day of November and finishes at sundown. It is the day before All Souls’ Day. “Oh blest communion, fellowship divine! We feebly struggle, they in glory shine; yet all are one in Thee, for all are Thine. Alleluia!”
