What is an Ordo?
The Ordo tells you which Mass and Office are to be said on a particular day, whether any commemorations or other liturgical rites are to take place, whether votive Masses are permitted, etc. If you are simply following the Universal Calendar, you may get a hang of the calendar and rubrics to the point that you do not need to use an Ordo, particularly if you are not canonically bound to the recitation of the Office. But if you are a cleric, or your diocese or religious order has particular feasts, or if the bishop has ordered an oratio imperata to be said at Mass, or anything else not covered by the Universal Calendar, then an Ordo becomes much more helpful and perhaps indispensable to ensure you are fulfilling your canonical obligations. For laity who pray the Office from devotion, it just makes life easier for those who have not learned the rubrics. Even if you do have a good grasp of the rubrics, there are complicated situations that sometimes arise (less so in the "1962" books).
