How long is 355 days

To obtain sufficient days for his new months, he is then said to have deducted one day from the day months, thus having 56 days to divide between January and February. But since the Romans had, or had developed, a superstitious dread of even numbers, January was given an extra day; February was still left with an even number of days, but as that month was given over to the infernal gods, this was considered appropriate.

The system allowed the year of 12 months to have days, an uneven number. The so-called Roman republican calendar was supposedly introduced by the Etruscan Tarquinius Priscus B.

The Roman republican calendar was a dating system that evolved in Rome prior to the Christian era. According to legend, Romulus, the founder of Rome, instituted the calendar in about B.

This dating system, however, was probably a product of evolution from the Greek lunar calendar, which in turn was derived from the Babylonian. The original Roman calendar appears to have consisted only of 10 months and of a year of days. The Roman ruler Numa Pompilius is credited with adding January at the beginning and February at the end of the calendar to create the month year. In B. By the 1st century B. The occasional intercalation of an extra month of 27 or 28 days, called Mercedonius, kept the calendar in step with the seasons.

The confusion was compounded by political maneuvers. The Pontifex Maximus and the College of Pontiffs had the authority to alter the calendar, and they sometimes did so to reduce or extend the term of a particular magistrate or other public official. Finally, in 46 B. 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.

According to Plutarch, Caesar had previously made the wise decision to stay within the safety of his bedroom chambers on the 15th of March.

So Julius Caesar decided to attend the Senate on the 15th of March. On his way to the Senate, Caesar "accidentally" met up with the astrologer, Spurinna. Caesar then told the astrologer "The Ides of March are come. Calendars exhibit Webexhibit. A page from the "Calendars" exhibit What did a Roman calendar look like? How do you read the calendar?
