gregorian calendar
(wn) | Gregorian calendar
n 1: the solar calendar now in general use, introduced by
Gregory XIII in 1582 to correct an error in the Julian
calendar by suppressing 10 days, making Oct 5 be called Oct
15, and providing that only centenary years divisible by
400 should be leap years; it was adopted by Great Britain
and the American colonies in 1752 [syn: {Gregorian
calendar}, New Style calendar] |
gregorian calendar
(foldoc) | Gregorian calendar
The system of dates used by most of the world. The
Gregorian calendar was proposed by the Calabrian doctor
Aloysius Lilius and was decreed by, and named after, Pope
Gregory XIII on 1582-02-24. It corrected the Julian calendar
whose years were slightly longer than the solar year. It also
replaced the lunar calendar which was also out of time with
the seasons. The correction was achieved by skipping several
days as a one-off resynchronisation and then dropping three
leap days every 400 hundred years. In the revised system,
leap years are all years divisible by 4 but excluding those
divisible by 100 but including those divisible by 400. This
gives a mean calendar year of 365.2425 days = 52.1775 weeks =
8,765.82 hours = 525,949.2 minutes = 31,556,952 seconds.
leap seconds are occasionally added to this to correct for
irregularities in the Earth's rotation.
