Christian feast day: Mary, Help of Christians

Mary, Help of Christians is a Catholic title of the Blessed Virgin Mary, based on a devotion now associated with a feast day of the General Roman Calendar on 24 May. John Chrysostom was the first to describe this title, in 345 AD. Don Bosco also propagated the devotion. It is associated with the defense of Christian Europe, North Africa and the Middle East from non-Christians during the Middle Ages.
