The Liturgy of the Hours (also called the Divine Office or the Breviary) is the official prayer of the universal Church, traditionally prayed by priests, deacons, and members of religious orders throughout each day. In recent decades, many laypeople have discovered and embraced this ancient form of prayer.
The Hours divide the day into moments of prayer: Lauds (Morning Prayer), Daytime Prayer, Vespers (Evening Prayer), and Compline (Night Prayer). The Office of Readings allows for an extended meditation on Scripture and writings of the saints.
Digital apps like iBreviary and Universalis have made the Liturgy of the Hours more accessible than ever for busy laypeople who wish to unite their prayer with the worldwide Church.
