Page "Canonical hours" Paragraph 169

The East Syrian Rite ( also known as the Chaldean, Assyrian, or Persian Rite ) has historically been used in Syria, Mesopotamia, Persia, and Malabar.

The nucleus of the Daily Office is of course the recitation of the Psalter.

There are only three regular hours of service ( Evening, Midnight, and Morning ), with a rarely used Compline.

When East Syrian monasteries existed ( which is no longer the case ) seven hours of prayer were the custom in them, and three hulali ( sections ) of the Psalter were recited at each service.

This would accomplish the unique feat of the common recitation of the entire Psalter each day.
