Drawing of the fragmentary Fasti Antiates Maiores (ca. 60 BC), a Roman calendar from before the Julian reform, with the seventh and eighth months still named Quintilis ("QVI") and Sextilis ("SEX"), and the intercalary month ("INTER") in the far righthand column (see enlarged)

The Roman calendar changed its form several times between the founding of Rome and the fall of the Roman Empire. This article generally discusses the early Roman or pre-Julian calendars. The calendar used after 46 BC is discussed under Julian calendar. The common calendar widely used today known as the Gregorian calendar is a refinement of the Julian calendar where the length of the year has been adjusted from 365.25 days to 365.2425 days (a 0.002% change).
