Feast-day
Saint Jarlath's feast day is 6 June, which is the date of the translation of his relics to a church specially built in his honour next to the Cathedral of Tuam. His remains were encased in a silver shrine, from which the 13th-century church gained the name Teampul na scrín, that is the "church of the shrine", a perpetual vicarage united to the prebend of Kilmainemore in 1415.
In a note added to the Félire Óengusso and in other martyrologies, Iarlaithe's feast-day is recorded as 25 or 26 December.
