FWIW I think that, as the prayer of the entire Church, it’s best to follow the rubrics and pray the hours according to them, taking into consideration the calendar.
One can use one of the prescribed forms. In my attachment to a monastic community I have used in the past one of the approved Benedictine schemas (psalms on a 1-week cycle), but time being a constant problem for me I have settled on the 4-week LOH. As an oblate I am required to pray at least part of the office as my situation permits. For me, the LOH allows me to pray all offices on most days. Actually to chant them on most days in Gregorian chant.
I endeavour to pray it properly. Not to say I don’t make mistakes… I’ve seen Benedictine monks make mistakes too
The LOH does have many
legitimate variations though, for example choice of 1-year or 2-year lectionary for the Office of Readings.
