The First Roman calendar was the Romulean calendar, established by Romulus, the first king of Rome, when he founded Rome in 753 BC. It only had 10 months. The second calendar, the calendar of Numa, was established soon afterwards by the second king of Rome, Numa Pompilius. It had 12 months. Both these calendars were lunar. The Julian calendar was established by the Julius Caesar in 45 BC. He switched from a lunar to a solar calendar. Apart from some minor modifications introduced by Pope Gregory XIII in the 15th century AD, this is the calendar we still use today.
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.
The original Roman calendar was said to be invented by Romulus, the first king of Rome, at around 753 BCE (Before Common Era). The calendar started the year in March (Martius) and consisted of 10 months, with 6 months of 30 days and 4 months of 31 days. The winter season was not assigned to any month, so the calendar year only lasted 304 days with 61 days unaccounted for in the winter. The Romulean calendar was short lived. The second king of Rome, Numa Pompilius, reformed the calendar. The Calendar of Numa had twelve month. It had 6 months of 29 days and 6 months of 31 days. it remained a lunar calender.
Julius Caesar implemented several significant changes in Rome, including the expansion of the calendar to the Julian calendar, which standardized the length of the year. He reformed the tax system to increase efficiency and reduce corruption. Caesar also redistributed land to veterans and the poor, addressing social inequalities. Additionally, he centralized the bureaucracy and expanded citizenship to people in the provinces, enhancing loyalty to Rome.

Julian Calendar and the roman numerals
The exact calendar that we used today was created by Pope Gregory XIII in the mid-1700s. The original basis for this calendar was the Julian Calendar (the difference between them was the timing of leap years) and the Julian Calendar was invented by Julius Caesar, Emperor of Rome.
The Julian Calendar was a calendar reform by Julius Caesar in Rome, introduced in 46 BC. The Julian Calendar divided the year into 365 days and 12 months, with a leap day every 4 years.
The calendar has been changed a number of times. Julius Ceasar introduced calendar reforms in ancient Rome that were still in use by some countries (notably Russia) in the 20th century. The m

The very first calendar established by Romulus the founder of Rome and its first king (the calendar of Romulus) only had ten months: March to December (Martius to Decembris). The month was called Decembris because it was the tenth month. The name is derived from decem, the Latin for ten. The second king of Rome, Numa Pomplius, introduced a new calendar (the calendar of Numa) and created twelve months by adding Ianuarius and Ferbuarius (January and February). The year still started in March and December remained the tenth month.
