Roman calendar

The Roman calendar changed its form several times between the founding of Rome and the fall of the Roman Empire. The common calendar widely used today is known as the Gregorian calendar and is a refinement of the Julian calendar where the average length of the year has been adjusted from 365.25 days to 365.2425 days (a 0.002% change). From at least the period of Augustus on, calendars were often inscribed in stone and displayed publicly. Such calendars are called fasti.
