Pray the Novena
A novena is typically nine days of prayer in preparation of a celebration of a feast day. At the National Shrine of The Divine Mercy, the Chaplet of Divine Mercy Novena is recited perpetually at the Hour of Great Mercy — the three o'clock hour.
The Chaplet can be said anytime, but the Lord specifically asked that it be recited as a novena. He promised, "By this Novena (of Chaplets), I will grant every possible grace to souls."
