Acta Apostolicae Sedis
Official gazette of the Holy See
Acta Apostolicae Sedis, often cited as AAS, is the official gazette of the Holy See, appearing about twelve times a year. It was established by Pope Pius X on 29 September 1908 with the decree Promulgandi Pontificias Constitutiones, and publication began in January 1909. It contains all the principal decrees, encyclical letters, decisions of Roman congregations, and notices of ecclesiastical appointments. 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.
