Lauds
the traditional morning prayer of the Western Church, constituting with matins the first of the seven canonical hours
derived from the three last psalms in the office (148, 149, 150), in all of which the word laudate is repeated frequently, and to such an extent that originally the word Lauds designated the end, that is to say, these three psalms with the conclusion.
The Seven “hours” are: matins and lauds (usually counted as a single hour), in the middle of the night; prime, at sunrise; terce, 9 a.m.; sext, noon; none, 3 p.m.; vespers, sunset; and compline, bedtime.
