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."
austina a different intention:
All mankind, especially sinners; the souls of priests and religious;
all devout and faithful souls; those who do not believe in God and
those who do not yet know Jesus; the souls who have separated
themselves from the Church; the meek and humble souls and the souls of
little children; the souls who especially venerate and glorify His
mercy; the souls detained in purgatory; and souls who have become
lukewarm.
"I desire that during these nine days you bring souls to the fountain of
My mercy, that they may draw therefrom strength and refreshment and
whatever grace they have need of in the hardships of life, and
especially at the hour of death."
