what was the first month of the roman calendar?
january
traditionally, the original roman calendar consisted of 10 months totaling 304 days, winter being considered a month-less period. around 713 bc, the semi-mythical successor of romulus, king numa pompilius, is supposed to have added the months of january and february, so that the calendar covered a standard lunar year (354 days). although march was originally the first month in the old roman calendar, january became the first month of the calendar year either under numa or under the decemvirs about 450 bc (roman writers differ). in contrast, each specific calendar year was identified by the names of the two consuls, who entered office on may 1 or march 15 until 153 bc, from when they entered office on january 1.
