In 45 B.C., New Year’s Day is celebrated on January 1 for the first time
in history as the Julian calendar takes effect.
Soon after becoming Roman dictator, Julius Caesar decided that the
traditional Roman calendar was in dire need of reform. Introduced around
the seventh century B.C., the Roman calendar attempted to follow the
lunar cycle but frequently fell out of phase with the seasons and had to
be corrected. In addition, the pontifices, the Roman body charged with
overseeing the calendar, often abused its authority by adding days to
extend political terms or interfere with elections.
In designing his new calendar, Caesar enlisted the aid of Sosigenes, an
Alexandrian astronomer, who advised him to do away with the lunar cycle
entirely and follow the solar year, as did the Egyptians. The year was
calculated to be 365 and 1/4 days, and Caesar added 67 days to 45 B.C.,
making 46 B.C. begin on January 1, rather than in March. He also decreed
that every four years a day be added to February, thus theoretically
keeping his calendar from falling out of step. Shortly before his
assassination in 44 B.C., he changed the name of the month Quintilis to
Julius (July) after himself. Later, the month of Sextilis was renamed
Augustus (August) after his successor.
Celebration of New Year’s Day in January fell out of practice during the
Middle Ages, and even those who strictly adhered to the Julian calendar
did not observe the New Year exactly on January 1. The reason for the
latter was that Caesar and Sosigenes failed to calculate the correct
value for the solar year as 365.242199 days, not 365.25 days. Thus, an
11-minute-a-year error added seven days by the year 1000, and 10 days by
the mid-15th century.
The Roman church became aware of this problem, and in the 1570s Pope
Gregory XIII commissioned Jesuit astronomer Christopher Clavius to come
up with a new calendar. In 1582, the Gregorian calendar was implemented,
omitting 10 days for that year and establishing the new rule that only
one of every four centennial years should be a leap year. Since then,
people around the world have gathered en masse on January 1 to celebrate
the precise arrival of the New Year.
