Is it right to call a calendar of days (13 numbers and 20 names) as a calendar. Do we americans and europeans have a DAY calendar, and is it 7 days or 28 years. A week cycles only 7 years in a 365-day calendar without leap days. So does this mean a 7-year calendar exists besides the 28-year.
The Romans had three calendars over the 1,200 years of their history. Only the first one, the Romulean calendar created by Romulus, Rome's first king, had 10 months and this lasted only for about 40 years. The second king of Rome, Numa Pompilius, reformed the calendar and created one with 12 months (the calendar of Numa). The Julian calendar, created by Julius Caesar, also had 12 months. Caesar also switched from a lunar to a solar calendar.
