TIME fact 6:TIME: part 6
Today January 1 is the first day of every new year. This was not always the case.
Most cultures and calendars placed the start of the new year in Spring. As Spring shows
signs of new growth, it was reasonable that a new year would begin at the same time. In 46
B. C., Julius Caesar introduced his Julian calendar. The Julian calendar reorganized the
Roman calendar form a lunar calendar to a solar calendar. Julius Caesar also moved the
start of the new year from March 1, to January 1. The Julian calendar became the basis for
today's Gregorian calendar. When the Gregorian calendar was introduced in 1582, January 1
remained the first day of the new year.
Even after the adoption of the Gregorian calendar in England and the American colonies,
March 25 remained the start of the new year. This date was intended to represent the
vernal equinox. Under this system, March 24, 1700, was followed by March 25, 1701. Though
the Gregorian calendar was adopted in 1582, it was not until 1752 that the English
government made January 1, the start of the new year.
As stated earlier (TIME 1) a calendar year is exactly 365 days, 5 hours, 48 minutes, and
46 seconds. Even though this is scientifically true our measurement of time has not been
that accurate. The longest year was in 46 B. C.. This is the year that Julius Caesar
introduced the Julian calendar. He added two extra months and 23 extra days to February to
make up for the accumulated error in the previously used Egyptian calendar. This made the
year 46 B. C. a total of 455 days long. ( I would have probably still been behind in my
work)
In 1582 the Gregorian Calendar was introduced. Pope Gregory decreed that October 5 would
be October 15. This eliminated 10 days (and my birthday) from that year to make up for the
accumulated error of the Julian calendar. Thus 1582 was the shortest year having only 355
days. It was not the shortest year for the entire world however. Most Catholic European
countries changed to the Gregorian calendar within 2 years of its introduction. Most
Protestant continental countries adopted the Gregorian calendar in 1699-1700. As suggested
above, England and its colonies did not change to the Gregorian calendar until 1752.
Sweden changed to this calendar in 1753. Asian countries were much slower to adopt the
Gregorian calendar with most complying by the end of the 19th century. China did not adopt
the Gregorian calendar until 1912. Turkey began using it in 1917, while Russia waited
until 1918.
To change dates from the Julian calendar to the Gregorian calendar one must: add 10 days
to dates October 5, 1582, through February 28, 1700; after that date add 11 days through
February 28, 1800; add 12 days through February 28, 1900; and add 13 days through February
28, 2100.
