Chapter 15. At what times of the year Alleluia is to be said

FROM the holy Feast of Easter until Pentecost, without interruption, let Alleluia be said both with the Psalms and the responsories. From Pentecost until the beginning of Lent, it is to be said at the Night-Office with the six latter Psalms only. But on every Sunday out of Lent let the Canticles,” Lauds, Prime, Tierce, Sext and None be said with Alleluia: Vespers, however, with an antiphon. The responses are never to be said with Alleluia, except from Easter to Pentecost.
