Are the glorious mysteries of the rosary used from Dec 24 to Lent?
No, for those who do not say the entire rosary everyday, the
Church has recommended a plan, wherein you pray the entire rosary
twice a week:
Sunday - Glorious
Monday - Joyful
Tuesday - Sorrowful
Wednesday - Glorious
Thursday - Luminous
Friday - Sorrowful
Saturday - Joyful
That being said, in the old days, when there were only three
sets of mysteries, the entire rosary was prayed in six days, so
Sunday was usually reserved for the set of mysteries of the season
in which you were, thus from 24 December until the Epiphany, you
said the Joyful mysteries on Sunday, then the Sorrowful during
Lent, and the Glorious during Easter.
