A chaplet is a devotional prayer counted on beads, and the word can also refer to the set of prayers itself. Usually shorter than a full rosary, each chaplet is tied to a particular devotion of the Church.
Here you will find the Chaplet of Divine Mercy given to St. Faustina, the St. Michael chaplet of nine salutations to the angelic choirs, the Seven Sorrows chaplet of Our Lady, and chaplets in honor of St. Jude, St. Anthony and other saints. Many include a prayer card with instructions.
The Hour of Mercy: Our Lord asked St. Faustina to pray the Divine Mercy Chaplet at three o'clock, the hour of His death. The words are in our Divine Mercy Chaplet prayer.
