He wanted the year to begin in January since it contained the festival of the god of gates later the god of all beginnings , but expulsion of the Etruscan dynasty in B.
In order to prevent it from becoming too far out of step with the seasons, an intercalary month, Intercalans, or Mercedonius from merces, meaning wages, since workers were paid at this time of year , was inserted between February 23 and It consisted of 27 or 28 days, added once every two years, and in historical times at least, the remaining five days of February were omitted.
Intercalation was the duty of the Pontifices, a board that assisted the chief magistrate in his sacrificial functions. The reasons for their decisions were kept secret, but, because of some negligence and a measure of ignorance and corruption, the intercalations were irregular, and seasonal chaos resulted.
In spite of this and the fact that it was over a day too long compared with the tropical year, much of the modified Roman republican calendar was carried over into the Gregorian calendar now in general use.
Much of the knowledge we now have about early Roman calendars came from Ovid, a Roman born in 43 B. Both of them had access to historical documents that are no longer extant. Ovid claimed that his information was "dug up in archaic calendars," so it was already ancient over two thousand years ago.
Initially, it contained only ten months. It has been suggested that those month lengths reflected growth cycles of crops and cattle. When compared with the solar year, it had an uncounted winter period of approximately sixty days. Romulus, the legendary first king, was said to have made extensive changes to those month lengths, assigning twenty-nine days to some and thirty-one to others.
Both Ovid and Plutarch said that Martius , originally the first month, was named after Mars, the Roman god of war. Six of the other original ten were simply numbered as Quintilis thru Decembris fifth thru tenth but there were already disagreements when Ovid wrote, two thousand years ago, as to the sources of names for what were originally the second thru fourth, Aprilis , Maius and Junius. These disagreements continue to the present time. When writing about April, Ovid said "I have come to the fourth month, full of honor for you; Venus, you know both the poet and the month are yours.
Jakob Grimm, a later authority, opposed this stating it may have originated from the name of a god or hero named Aper or Aprus. Maius was said by some to be named after the goddess Maia , a daughter of Atlas, and Junius "is indirectly named after the goddess Juno , the Roman equivalent of Frigga. Januarius became part of the calendar within half a century after Rome was founded because Plutarch said that Numa, the king who followed Romulus, made it the first month of the year and made February the last.
One historian assigns that action an exact date by stating that "January and February were added to an original Roman calendar of only ten months in B. Ovid quoted Janus as saying "The ancients called me chaos, for a being from of old am I. On the first day of the month there goes in procession no less a personage than Janus himself, dressed up in a two-faced mask, and people call him Saturnus, identifying him with Kronos. Early Romans believed that the beginning of each day, month and year were sacred to Janus.
They thought he opened the gates of heaven at dawn to let out the morning, and that he closed them at dusk. This eventually led to his worship as the god of all doors, gates, and entrances. Some say Februarius got its name from a goatskin thong called a februa "means of purification. During the festival, a februa was wielded by priests who used it to beat women in the belief that it would make a barren woman fertile. That indicates Februarius was observed in pre-Romulan times when months had as few as twenty days.
Romans always reconciled differences between calendar and solar year lengths during the "Month of Purification. Even in our time, leap year is observed with a day February.
To purists, "leap day" is February 24, not the 29th. Plutarch wrote: "Numa This amendment, however, itself, in course of time, came to need other amendments. But as the moon does not complete thirty days in each month, and so there are fewer days in the lunar year than in that measured by the course of the sun, he interpolated intercalary months and so arranged them that every twentieth year the days should coincide with the same position of the sun as when they started, the whole twenty years being thus complete.
He also established a distinction between the days on which legal business could be transacted and those on which it could not, because it would sometimes be advisable that there should be no business transacted with the people. This month also began after the 23rd day of Februarius.
It was observed every second year and was said to have had a length of either 22 or 23 days, with the remaining five days of Februarius added after them.
Who calls? Bid every noise be still. Who is it in the press that calls on me? I hear a tongue, shriller than all the music, Cry "Caesar"! Beware the Ides of March. What man is that? A soothsayer bids you beware the Ides of March. Set him before me; let me see his face. Fellow, come from the throng; look upon Caesar.
What say'st thou to me now? Speak once again. He is a dreamer; let us leave him. Caesar asks him to come closer and repeat what he has just said. Later, when he meets the Soothsayer again on the way to the Senate, he confidently says to him, "The Ides of March have come.
According to to historical writer C. If, however, Julius Caesar took care on that one day - then all would be well.

Connect and share knowledge within a single location that is structured and easy to search. I did some research on Wikipedia and concluded three months were added because of the Roman empire. July, June, and August. Is this correct? If so, perhaps the book was referring to two months added for Julius Caesar?
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 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 days with 61 days unaccounted for in the winter. King Numa Pompilius reformed the calendar around BCE by adding the months of January Ianuarius and February Februarius to the original 10 months, which increased the year's length to or days.
The addition of January and February meant that some of the months' names no longer agreed with their position in the calendar September - December. The Roman calendar was still flawed after adding January and February, as well as the days and months needed to keep the calendar in line with the seasons. Many attempts were made to align the calendar with the seasons but all failed. An extra month was added to the calendar in some years to make up for the lack of days in a year.
The insertion of the intercalary month was made by the pontifex maximus, the high priest of the College of Pontiffs in ancient Rome. However, this system was flawed because the Roman calendar year defined the term of office of elected officials, thus a pontifex maximus could control the length of the year depending on their political agenda.
When Julius Caesar became pontifex maximus, he reformed the calendar by getting rid of the intercalary months. The Julian calendar was created, then completed during his successor Augustus' reign. According to dateandtime. It wasn't until Julius Caesar that that we got the Julian calendar but it wasn't perfected until Agustus Caeser's reign. Resource sited here. The two answers from rancho and EvanM say the Julian calendar was not completed or perfected until during the reign of Augustus the first emperor.
Actually the calendar was in its final, complete, and perfect form when introduced by Julius Caesar in 44 BC but the College of Pontiffs who administered it made what we might consider to be a very basic and obvious mistake.
The Julian calendar has a leap year every fourth year, counted exclusively. If a year is a leap year it is not counted. The harvest was being celebrated before the crops even had been taken in. As Suetonius complained, "Harvest festivals did not come in summer nor those of the vintage in the autumn" Life of Julius , XL.
That year, a reformed calendar based on the solar year was introduced by Caesar, who first had heard about it, relates Lucan Pharsalia , X.
With the advice of the Alexandrian astronomer Sosigenes, the missing ninety days were intercalated, extending this ultimus annus confusionis "the last year of confusion" to days Macrobius, Saturnalia , I. To correct for the days that were lost in the old lunar calendar of the Republic, one or two additional days were added at the end of those months with 29 days.
This, then, was the new Julian calendar , which was introduced on January 1, 45 BC, on the first new moon after Bruma. Because the solar year is approximately a quarter day longer than the calendar year, a single intercalary day also was to be inserted every four years, when February 24 would be counted twice. This was a bissextile or leap year, since that date was the "twice sixth" day bissextus before the Kalends of March.
The notion of February 29 is a modern construct. When Caesar was assassinated in 44 BC, Quinctilis, the month in which he had been born, was renamed Julius July in his honor, although this change in the name of the month was ignored until made legal after the appearance of a comet four months later during games sponsored in July by Octavian, which, recounts Dio, was understood to be a sign of Caesar's apotheosis XLV.
Octavian also is thought to have moved these games to late July to overshadow those sponsored by Brutus earlier that month. Hearing of their announcement, Cicero responded in a letter to Atticus, "Good heavens! Confound their impudence! Cicero also joked in a letter just four days after the new calendar had been introduced that the constellation of Lyre was rising "by Caesar's decree. But the pontiffs mistakenly adjusted for leap year every three years having counted inclusively and inserted too many intercalary days.
Only then, after the superfluous days had been corrected and intercalation was resumed, did the Julian calendar function as intended, with February gaining an extra day every four years. In honor of this reform, Sextilis was renamed Augustus. It was that month, says Macrobius I. August, too, was the eighth month and appropriate for someone who earlier had been named Octavian. The four-year cycle of the Julian year averaged Rather, it was a bit more than eleven minutes too long, gaining almost a day every years, an accumulation that, by the mid-sixteenth century, amounted to approximately ten days.
