A Marian year is a designation given by the Catholic Church to calendar years in which Mary the mother of Jesus is to be particularly reverenced and celebrated. Marian years do not follow a set pattern; they may be declared by a bishop for his diocese, or a national conference of bishops for a country.
In Church history, only two international Marian years have been pronounced, by Pope Pius XII in 1954, and Pope John Paul II in 1987.[1] In both years, Marian devotion, Marian pilgrimages, and Marian meetings were promulgated.
