Arrangement of the Psalms in the Divine Office
According to the Apostolic Constitution "Divino Afflatu"
of Pope St. Pius X
November 1, 1911; Effective January 1, 1913


This chart indicates which Psalms are recited during each Hour of the Divine 
Office, the prayer of the Church that sanctifies the hours of the day after 
the practice from Old Testament times:  "Seven times a day I have given 
praise to thee, for the judgments of thy justice" (Psalm 118:164/DR).  Thus, 
we have Matins/Lauds (midnight/before dawn), Prime (dawn), Terce (mid 
morning), Sext (midday), None (mid afternoon), Vespers (dusk), and Compline 
(after sunset).

In 1911, Pope St. Pius X provided that the 150 psalms of the Psalter be 
distributed among the different day and night hours in such a way that 
it was possible to recite the whole Psalter in the course of a week.

Although the Most Holy Rosary and other private devotions are most 
commendable, it is the Divine Office, which includes Holy Mass, that is 
the Church's official and most highly indulgenced prayer.

It would be a most commendable spiritual practice for those who are 
unable to say the entire Divine Office at least to say all, or even 
some, of the Psalms pertaining to each day.
