Passion Sunday
In the 1955 Holy Week revisions, Passion Sunday was formally renamed from "Dominica Passionis" or "Dominica de Passione" ("Sunday of the Passion") to "Dominica I Passionis", "First Sunday of the Passion" or "First Sunday of Passiontide". Palm Sunday, formerly "Dominica in Palmis" ("Sunday in Palms") became "Dominica II Passionis seu in Palmis" ("II Sunday of the Passion or in Palms").
