I will reiterate my usual recommendation. Read the General Instruction thoroughly, and study the rubrics as well. Looking at on-line apps also helps.
It’s essential to learn three things: the basic structure of each Hour, the basic layout of the books and the levels of celebration: seasons, saints (memorial, feast or solemnity) and what their requirements are; you will find that all in the General Instruction. Also procuring an Ordo is of great help (should be available from your diocese or Conference of Bishops; some dioceses even publish them on-line).
It will take time but eventually it will all be second nature. You’ll look in the Ordo, confirm what the day is (feria, optional memorial, mandatory memorial, feast or solemnity), and instinctively know where to set up the ribbons for the Hour you are about to recite.
I know it sounds complicated but it really isn’t so bad. The joke in monasteries is when a novice has finally figured out the Liturgy of the Hours, he’s ready to make his profession.
Lastly, don’t be afraid to ask questions here. Many of us are very familiar with the LOTH although we don’t all work from the same books; our page numbers won’t correspond, but if we refer you to say the “common of Martyrs”, you should be able to find that in your books without needing the page number once you’re familiar with their layout. We won’t bite your head off if you ask, promised
A bit of homework and practice will go a long way to making the Office second-nature!
Thank you…
