Acta Apostolicae Sedis (Latin for 'Acts of the Apostolic See'), often cited as AAS, is the official gazette of the Holy See,[1] appearing about twelve times a year.[2] It was established by Pope Pius X on 29 September 1908 with the decree Promulgandi Pontificias Constitutiones, and publication began in January 1909.[2] It contains all the principal decrees, encyclical letters, decisions of Roman congregations, and notices of ecclesiastical appointments.[3] The laws contained in it are to be considered promulgated when published, and effective three months from date of issue, unless a shorter or longer time is specified in the law.[3][4][5]
