The Little Hours or minor hours are the canonical hours other than the three major hours. The major hours are those whose traditional names are matins, lauds and vespers. Since the reform of the Liturgy of the Hours mandated by the Second Vatican Council, they are called the office of readings, morning prayer and evening prayer. The minor hours, so called because their structure is shorter and simpler than that of the major hours, are those celebrated between lauds and vespers together with compline.
Hours between morning and evening prayer in the Roman Rite
Between lauds and vespers, both Western Christianity and the Eastern Orthodox Church traditionally celebrate three canonical hours, consisting mainly of psalms and bearing names derived from the hours of daylight: terce, sext and none. These prayer times derive from ancient Jewish practice and are mentioned in the Acts of the Apostles. They also commemorate the events of the Passion of Jesus. The Roman Rite also had prime. This has been suppressed by mandate of the Second Vatican Council. In English, the other three hours celebrated between morning and evening prayer are now in the ICEL four-volume edition of the Liturgy of the Hours called midmorning, midday and midafternoon prayer, and collectively the daytime hours; and in the three-volume edition in use in most English-speaking countries outside of the United States they are indicated as before noon, midday and afternoon, and collectively as prayer during the day. Celebration of these three hours is in general obligatory for those who lead a contemplative life. For others, recitation of all three is recommended and, in order to preserve the tradition of praying during the day's work, those who have the duty to celebrate the Liturgy of the Hours are obliged to say at least one. The Latin collective term is hora media. All three have the same structure. They begin with the versicleDeus in adiutorium meum intende and its response, followed by Gloria Patri and Alleluia. A hymn is then said or sung, after which come the psalmody, and a short reading, followed by a versicle and a prayer. Two psalmodies are provided: one that varies from day to day for use by all, and a complementary one, with psalms chosen mainly from among the gradual psalms, for use by those who say one or two additional hours.
During Great Lent, the Little Hours undergo significant changes on weekdays, and are celebrated with greater solemnity than during the rest of the year. On weekdays, in addition to the normal three Psalms, a kathisma from the psalter is read, the choir chants special Lenten hymns in place of the Troparion and Kontakion of the day, and the Sixth Hour has added to it a special Troparion, Prokeimena, and a reading from the Old Testament. Finally, as at all Lenten services, the Prayer of St. Ephraim is read with everyone making prostrations. During Holy Week, on Monday, Tuesday and Wednesday, the services are similar to those during Great Lent, except that instead of the normal Lenten hymns which replace the Kontakion, the Kontakion of the day is chanted. Also, the four Gospels are read in their entirety over the course of these three days at the Third Hour, Sixth Hour, and Ninth Hour. On Great Thursday, Friday and Saturday, the Little Hours are more like normal, except that a Troparion of the Prophecy, prokeimena, and a reading from Jeremiah are chanted at the First Hour on Great Thursday. On Great Friday, the Royal Hours are chanted. During the Lesser Lenten seasons the Little Hours undergo changes similar to those during Great Lent, except the hymns are usually read instead of chanted, and there are no additional Kathismata on weekdays. In addition, on weekdays of the Lesser Fasts, the Inter-Hours will be read. These Inter-Hours follow the same general outline as the Little Hours, except they are shorter, one Inter-Hour following each of the Little Hours.
Festal Seasons
The Royal Hours are the most liturgically splendid celebration of the Little Hours. This service takes its name from the fact that it used to be officially attended by the Emperor and his court at Hagia Sophia in Constantinople. Three times a year, on the Eve of the Nativity, Eve of Theophany, and Good Friday, the Little Hours are celebrated as one continuous service. The priest vests in Phelonion, and the deacon vests fully and serves. The holy doors and curtain are open for most of the service, and the gospel book is placed on an analogion in the center of the temple. At the beginning of each Hour the priest or deacon censes the Gospel, Icons and people. At each of the Hours, one of the three fixed Psalms is replaced by a Psalm that is significant to the Feast being celebrated; the Troparion and Kontakion of the day are replaced by numerous hymns chanted by the choir; and each Hour has an Old Testament reading, a Prokeimenon, and an Epistle and Gospel. The Paschal Hours are celebrated during Bright Week, and are the most joyous of the entire year. At this time the Little Hours are completely different from any other time of the year. Everything is sung joyfully rather than being read. Each of the Little Hours is exactly the same: No Psalms are read; rather, each Paschal Hour is composed of hymns taken primarily from the Paschal Vigil. On the Sunday of Pascha itself, the priest vests fully, as for Divine Liturgy; on the other days of Bright week, he wears Epitrachelion, Epimanikia and Phelonion. The Holy Doors and Curtain are open.
