IV. The Celebration of This Sacrament

From The Catechism of the Catholic Church

1572
Given the importance that the ordination of a bishop, a priest, or a deacon has
for the life of the particular Church, its celebration calls for as many of the
faithful as possible to take part. It should take place preferably on Sunday,
in the cathedral, with solemnity appropriate to the occasion. All three
ordinations, of the bishop, of the pRiest, and of the deacon, follow the same
movement. Their proper place is within the Eucharistic liturgy.
