For almost 50 years, the daily schedule of Mormon missionaries across the globe — whether in Boston or Berlin, São Paulo or Seoul — has been nearly identical and vigorously enforced.
Rise by 6:30, eat breakfast and exercise. The missionaries, who generally travel in pairs, then study scriptures for a couple of hours, head out the door for proselytizing by midmorning, wolf down lunch, engage in more proselytizing, have dinner, and then return to their apartments by 9 with lights out by 10 or 10:30.
Now that rigid routine has been loosened, allowing flexibility based on differing cultures from country to country.
