what is gregorian calender?

Answer 1

(m)

The Gregorian calendar is the most widely used calendar in the world. A modification of the Julian calendar, it was first proposed by the Calabrian doctor Aloysius Lilius, and was decreed by Pope Gregory XIII, for whom it was named, on 24 February 1582 via the papal bull Inter gravissimas. Years in the calendar are numbered from the traditional birth year of Jesus, which was labeled the "anno Domini" (AD) era[1], and is sometimes labeled the "common era" (CE).

The Gregorian Calendar was devised both because the mean Julian Calendar year was slightly too long, causing the vernal equinox to slowly drift backwards in the calendar year, and because the lunar calendar used to compute the date of Easter had grown conspicuously in error as well.


Tomb of Pope Gregory XIII in St. Peter's Basilica.The Gregorian calendar system dealt with these problems by dropping a certain number of days to bring the calendar back into synchronization with the seasons, and then slightly shortening the average number of days in a calendar year, by omitting three Julian leap-days every 400 years. The days omitted are the century years, i.e.: 29 February 1700, 1800, 1900, 2100, 2200, 2300, 2500, 2600, 2700, 2900 etc.

Answer 2

That is the calendar used in most of the world today. The calendar has to deal with the fact that the length of the year is a bit less than 365.25 days, so handling the fraction has been a problem. On the advice of his astronomers, Pope Gregory, about 1572, promulgated the new calendar, which was adopted by much of the world, but not by England until about 200 years later. The error in the previous (Julian) calendar had, by Gregory's time, added up to about 11 days, so that number of days was skipped. (The Julian calendar assumes the year as 365.25 days exactly.) The adjustment made in the Gregorian calendar was to fudge the century years, which previously were leap years; now, they will only be leap years if the year is divisible by 400 (as the year 2000 was). This has an error of about one day in 3323 years, so I assume that the year 4000 will not be a leap year.

Answer 3

Sorry one individual that responded to this question was wrong. I figured that I would fix their mistake. The Gregorian Calender was decreed by Pope Gregory XIII. It was not invented by him. It was invented by a monk named Dionysus to assist Bishops. The first year is often referred to as A.D. This means Anno Domini or Year of Our Lord. The years following this are called the C.E. or Commen Era. The years previous are called B.C.E. Before Common Era.
