The original Roman calendar is believed to have been a lunar calendar, which may have been based on one of the Greek lunar calendars. As the time between new moons averages 29.5 days its months were constructed to be either hollow (29 days) or full (30 days).he calendar year originally began on 1 March, as is shown by the names of the six months following June (Quintilis = fifth month, Sextilis = sixth month, September = seventh month, etc.).
Julius Caesar and  Augustus did not add two months to the year named after them. The  original calendar established by Romulus, the first king of Rome,  in the mid-8th centâ¦ury (the Romulean calendar) had ten months. Numa  Pompilius, the second king of Rome, reformed the calendar in the  late 8th or early 7th century BC.
