Canonical hours

Canonical hours are ancient divisions of time (also called "offices"), developed by the Catholic Church, serving as increments between prayers. The practice grew from the Jewish practice of reciting prayers at set times of the day: for example, in the book of Acts, Peter and John visit the temple for the afternoon prayers. Already well-established by the ninth century, these canonical offices consisted of eight daily prayer events and three (or four) nightly divisions (called "nocturnes", "watches," or "vigils"). Building on the recitation of psalms and canticles from Scripture, the Church has added (and, at times subtracted) hymns, hagiographical readings, and other prayers. The practice of observing canonical hours are maintained by many Churches, such as the Catholic, Orthodox, and Anglican communions.

The daily events were:

(at dawn) Matins ("MATT'-inz") called "Orthos" in Eastern Churches

(at dawn) Lauds ("lawds") later separate from Matins; aka "Morning Prayer" or "The Praises."

(at ~6 AM) Prime (the "first hour")

(at ~9 AM) Terce (the "third hour")

(at Noon) Sext (the "sixth hour")

(at ~3 PM) Nones (the "ninth hour")

(at sunset) Vespers (aka "Evensong" or "Evening Prayer")

(at bedtime) Compline ("COMP'-lin", aka "Night Prayer")

The remainder of this article is divided into three sections: the Anglican Usage, the Catholic usage, and the Orthodox usage.

Catholic Usage in the Roman Rite following the Second Vatican Council

Following the Second Vatican Council, the Catholic Church's Roman Rite simplified the observance of the canonical hours and sought to make them more accessible to the laity, hoping to restore their character as the prayer of the entire Church. The office of Prime was abolished, and the character of Matins changed so that it could be used at any time of the day as an office of Scriptural and hagiographical readings. Furthermore, the period over which the entire Psalter is recited has been expanded from one week to four.

Formerly referred to popularly as "The Divine Office", and published in four volumes according to the meteorological seasons "Spring", "Summer", "Fall", and "Winter", the Church now publishes the related liturgical books under the title "The Liturgy of the Hours", and issues them in four volumes according to the liturgical season: "Advent and Christmas", "Lent and Easter", "Ordinary Time Vol. I", "Ordinary Time Vol. II".

Current Catholic usage focuses on two major hours and from three to five minor hours:

The major hours

The major hours consist of Morning and Evening Prayer (or Vespers). The character of Morning Prayer is that of praise; of Evening Prayer, that of thanksgiving. Both follow the same format:

The minor hours

The daytime hours follow a simpler format:

The office of readings expands on the format of the daytime hours:

Night prayer has the character of preparing the soul for its passage to eternal life:

In each office, the psalms and canticle are framed by antiphons, and each concludes with the traditional Catholic doxology.

Liturgical variation

In addition to the basic four-week cycle of prayers for each of the canonical hours, the Church also provides an alternate collection of hymns, readings, psalms, canticles and antiphons, for use in marking specific dates on the Roman Calendar, which sets out the order of celebrations for the liturgical year. These alternate selections are found in the 'Proper of Seasons' (selections for Advent, Christmas, Lent and Easter), and the 'Proper of Saints' (selections for feast days of the Saints). A breviary is generally keyed to help the user navigate these overlays in the liturgy.
