Marian year
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. In both years, Marian devotion, Marian pilgrimages, and Marian meetings were promulgated.
