World Day of Peace

World Day of Peace, sometimes unofficially known as World Peace Day, is a feast day dedicated to peace  celebrated on January 1, on the Solemnity of Mary, Mother of God.

It was introduced in 1967 and inspired by the encyclicals Pacem in Terris and Populorum Progressio of John XXIII and Paul VI.
