In those places where the feast of Our Lady of Guadalupe has very special significance, the liturgical celebration may be transferred to another appropriate day. This is in accord with the General Instruction of the Roman Missal, no. 374, which states that “If any case of a graver need or of pastoral advantage should arise, at the direction of the Diocesan Bishop or with his permission, an appropriate Mass may be celebrated on any day except Solemnities, the Sundays of Advent, Lent, and Easter, days within the Octave of Easter, the Commemoration of All the Faithful Departed (All Souls’ Day), Ash Wednesday, and the days of Holy Week.”
