Chapter 8: On the Divine Office During the Night
In the winter time,
that is from the Calends of November until Easter,
the sisters shall rise
at what is calculated to be the eighth hour of the night,
so that they may sleep somewhat longer than half the night
and rise with their rest completed.
And the time that remains after the Night Office
should be spent in study
by those sisters who need a better knowledge of the Psalter
or the lessons.
From Easter to the aforesaid Calends of November,
the hour of rising should be so arranged that the Morning Office,
which is to be said at daybreak,
will follow the Night Office after a very short interval,
during which they may go out for the necessities of nature.
