146. “On Holy Saturday, the Church pauses at the Lord’s tomb, meditating his Passion and Death, his descent into Hell, and, with prayer and fasting, awaits his resurrection” (CDWDS, Lettera circolare sulla preparazione e celebrazione delle feste pasquali,73).
I’ve been in many places where bread and other objects were blessed on the day of Easter Eve. These Easter practices are discouraged until after the Vigil:
Popular piety should not be impervious to the peculiar character of Holy Saturday. The festive customs and practices connected with this day, on which the celebration of the Lord’s resurrection was once anticipated, should be reserved for the vigil and for Easter Sunday.
The Directory on Popular Piety and the Liturgy is online at the Vatican site.
