Canonical hours Canonical hours are divisions of time, developed by the Christian Church, serving as increments between the prescribed prayers of the daily round. A Book of Hours contains such a set of prayers.In the West, canonical hours may also be called offices, since they refer to the official set of prayer of the Roman Catholic Church that is known variously as the Divine Office (from the Latin officium divinum meaning "divine service" or "divine duty"), and the Opus Dei (meaning in Latin, "Work of God").

Agpeya The Coptic cycle of canonical hours is largely monastic, primarily composed of psalm readings. The Coptic equivalent of the Byzantine Horologion is the Agpeya. Seven canonical hours exist, corresponding largely to the Byzantine order, with an additional "Prayer of the Veil" which is said by Bishops, Priests, and Monks (something like the Byzantine Midnight Office). The Coptic terms for 'Matins' and 'Vespers' are 'The Morning Raising of Incense' and 'The Evening Raising of Incense' respectively. Agpeya
