Ranking of feast days
Feast days are ranked in accordance with their importance. In the post-Vatican II form of the Roman Rite, feast days are ranked (in descending order of importance) as solemnities, feasts or memorials (obligatory or optional). Pope John XXIII's 1960 Code of Rubrics, whose use remains authorized by the motu proprioSummorum Pontificum, divides liturgical days into I, II, III, and IV class days. Those who use even earlier forms of the Roman Rite rank feast days as doubles (of three or four kinds), Semidoubles, and Simples. See Ranking of liturgical days in the Roman Rite.
