Marian feast days are specific days of the year declared by the Catholic Church as being significant Marian days for the celebration of events in the life of the Blessed Virgin Mary and her veneration.
During the month of May, May devotions to the Blessed Virgin Mary take place in many Catholic regions. There is no firm structure as to the content of a May devotion. It includes usually the singing of Marian anthems, readings from scriptures, a sermon, and or presentation by local choirs. The whole rosary is prayed separately and is usually not a part of a Marian devotion, although Hail Mary's are included. The devotion, was promoted by Jesuits and spread to Jesuit Colleges and to the entire Latin church and since that time it has been a regular feature of Catholic life. Marian devotions may be held within the family, around a “May Altar” consisting of a table with a Marian picture decorated with many May flowers. The family would then pray together the rosary. May devotions exist in the entire Latin church and since that time have been a regular feature of Catholic life.
Traditionally, the month of October is "rosary month" in the Catholic Church,when the faithful are encouraged to pray the rosary if possible. Since 1571, Mary, Queen of the Holy Rosary, is venerated on October 7. Pope Benedict XVI, following all his predecessors, also encourages the rosary during the month of October:
