As revised after the Second Vatican Council, the Ambrosian liturgy of the hours uses for what once called matins either the designation "the part of matins that precedes lLauds in the strict sense" or simply "office of readings". Its structure is similar to that of the Roman Liturgy of the Hours, with variations such as having on Sundays three canticles, on Saturdays a canticle and two psalms, in place of the three psalms of the other days in the Ambrosian Rite and of every day in the Roman Rite.
