Republican Calendar Adds January and February Months in the Republican Calendar Month Namesįollowing another calendar reform, which later Roman writers attributed to Romulus' successor, Numa Pompilius, the Republican calendar was instituted. The winter season was not assigned to any month, so the year only lasted 304 days, with 61 days unaccounted for in the winter.

The resulting calendar, whose structure borrowed heavily from the ancient Greek calendar system, had only 10 months, with March (Martius) being the first month of the year. Moon phases in any location Only 10 Months at FirstĪccording to tradition, Romulus, the legendary first king of Rome, oversaw an overhaul of the Roman calendar system around 738 BCE. This basic structure was preserved through the centuries, which is the reason why we use months today. It is believed that the original Roman calendar was a lunar calendar that followed the phases of the Moon. The Republican calendar was derived from a line of older calendar systems whose exact design is largely unknown. It was used until 45 BCE, when it was replaced by the Julian calendar. Also known as the Republican calendar, it is the earliest calendar system from Rome for which we have historical evidence. Here, we focus mainly on the calendar used in the Roman Republic (509-27 BCE).

However, because the calendar was reformed and adjusted countless times over the centuries, the term essentially denotes a series of evolving calendar systems, whose structures are partly unknown and vary quite a bit. The Roman calendar is the time reckoning system used in ancient Rome. ©/matthewleesdixon What Is the Roman Calendar? Business Date to Date (exclude holidays).
