198. In the office of readings, this prayer is as a rule the prayer proper to the day. At night prayer, the prayer is always the prayer given in the psalter for that hour.
199. The concluding prayer at morning prayer and evening prayer is taken from the proper on Sundays, on the weekdays of the seasons of Advent, Christmas, Lent, and Easter, and on solemnities, feasts, and memorials. On weekdays in Ordinary Time the prayer is the one given in the four-week psalter to express the character of these two hours.
200. The concluding prayer at daytime prayer is taken from the proper on Sundays, on the weekdays of the seasons of Advent, Christmas, Lent, and Easter, and on solemnities and feasts.
