In winter, that is from the first of November until Easter, the brethren shall rise at what is calculated to be the eighth hour of the night, so that they may sleep somewhat beyond midnight and rise with their rest completed. If any time remain after Matins, let the brethren, who are lacking in knowledge of the psalter and lessons, employ it in study. From Easter to the aforesaid first of November let the hour of rising be so arranged that there be a very short interval after Matins, in which the brethren may go out for the necessities of nature, to be followed at once by Lauds, which should be said at dawn.
