There was no highlight of the day in the modern sense. Every day was just about the same, with all the time allotted to work of various kinds, study and prayer. Meals (one per day in winter, two in summer) were taken in complete silence and were not an opportunity for noisy chatter.
The implication of "highlight of the day" is selfish enjoyment, which is totally against the concept of the life in a monastery. Being a monk or nun meant putting God first in everything, then putting the work of God (prayer and so on) before all selfish considerations. The idea of "me" and "what I want" was considered the very least important part of life.
The only change to the standard routine would be on the many feast days, when particular saints would be honoured; some of these might involve a formal procession around the monastic precinct or even through the local town. "Feast" did not mean a large meal - it was a day of religious devotion to the saint with additions to the services and special hymns being sung.
