Calendar Before Julian

Calendar Before Julian. The julian calendar—the prevalent calendar in the christian world for the first millennium ce and part of the second millennium—was an improvement over the roman republican calendar that it replaced, but it was 11 minutes and 14. By the 8th century, people noticed the problem, and proposals for calendar reform were brought before popes during the middle ages.

The purpose of the calendar is to reckon past or future time, to show how many days until a certain event takes place—the harvest or a religious festival—or how long since. The roman calendar was reformed by julius caesar in 45 bce.
