Answer:
It was more precise than previous calendars.
Step-by-step explanation:
The author implies that the Julian calendar was more precise than previous calendars. The Julian calendar was introduced by Julius Caesar in 45 BCE to replace the Roman calendar, which had only ten months and 304 days. The Julian calendar had 12 months and 365 days with an additional day added every four years, known as a leap year. The extra day, called the intercalary day, was added to February, and this made the Julian calendar more precise than the previous Roman calendar. Therefore, the author implies that the Julian calendar was an improvement over the previous calendars in terms of precision.
