when are the mysteries of the rosary said
Rosary The prayers that essentially compose the Rosary are arranged in sets of ten Hail Marys with each set preceded by one Lord's Prayer and followed by one Glory Be, with perhaps the "Oh My Jesus" added, based on the apparitions at Fátima in 1917. During recitation of each set, known as a decade, thought is given to one of the Mysteries of the Rosary, which recall events in the lives of Jesus and Mary. The Glorious mysteries are said on Sunday and Wednesday, the Joyful on Monday and Saturday, the Sorrowful on Tuesday and Friday, and the Luminous Mysteries are said on Thursday. Normally, five decades are recited in a session. Various prayers are sometimes added after each decade (for example, the Fátima Prayer), at the beginning (in particular, the Apostles' Creed), and at the end (in particular, the Hail, Holy Queen). The rosary as a material object is an aid towards saying these prayers in the proper sequence.
Chaplet of the Divine Mercy On September 13, 1935, while Faustina was in Vilnius, she wrote of a vision of Jesus about the chaplet in her diary (Notebook 1 item 476).[8][9] Faustina stated that Jesus asked her to pray the chaplet and instruct others to do so. Although the chaplet is said on beads like the Rosary, it is about a third of the length of the Rosary, and unlike the Rosary that has evolved over the years, the form and structure of the chaplet has remained unchanged since Faustina attributed it to a message from Jesus.[9]
