Some sensible, but dry considerations for interrupted readings:
249. When the continuous reading is interrupted because of a solemnity or feast or special celebration, it is allowed during the same week, taking into account the readings for the whole week, either to combine the parts omitted with others or to decide which of the texts are to be preferred.
250. The office of readings also offers the option to choose, with a good reason, another reading from the same season, taken from The Liturgy of the Hours or the optional lectionary (no. 161), in preference to the second reading appointed for the day. On weekdays in Ordinary Time and, if it seems opportune, even in the seasons of Advent, Christmas, Lent, and Easter, the choice is open for a semicontinuous reading of the work of a Father of the Church, in harmony with the biblical and liturgical context.
251. The readings, prayers, songs, and intercessions appointed for the weekdays of a particular season may be used on other weekdays of the same season.
252. Everyone should be concerned to respect the complete cycle of the four-week psalter. [See GILH 100-109] Still, for spiritual or pastoral advantage, the psalms appointed for a particular day may be replaced with others from the same hour of a different day. There are also circumstances occasionally arising when it is permissible to choose suitable psalms and other texts in the way done for a votive office.
This last paragraph is of interest to me. I’ve done Liturgy of the Hours in parishes for over twenty years, but always weekly and usually seasonally. I’ve utilized this option often, especially for a weeknight evening prayer for people who don’t ordinarily pray the Hours. Some New Testament canticles seem appropriate for seasonal prayer: Philippians 2 for Lent, Revelation 19 for Easter, Ephesians 1 for Christmas strike me as having “spiritual or pastoral” advantage.
