Gregorian Calendar: Encyclopedia - Gregorian calendar

The Gregorian calendar is the calendar that is used nearly everywhere in the world. A modification of the Julian calendar, it was first proposed by the Neapolitan doctor Aloysius Lilius, and was decreed by Pope Gregory XIII, for whom it was named, on 24 February 1582 (Note: The papal bull Inter gravissimas was signed in the year 1581 for unknown reasons, but printed on 1 March 1582. Although the use of the date 1581 is often attributed to the supposed adoption by the papacy of a reckoning by which the year began on 25 March, other contemporaneous papal bulls have years that do not agree with March years, let alo ...

Gregorian Calendar: Encyclopedia II - Gregorian calendar - Proleptic Gregorian calendar The Gregorian calendar can, for certain purposes, be extended backwards to dates preceding its official introduction, producing the proleptic Gregorian Calendar. However, this proleptic calendar should be used with great caution. For ordinary purposes, the dates of events occurring prior to 15 October 1582 are generally shown as they appeared in the Julian calendar, and not converted into their Gregorian equivalents. However, events occurring in countries where the Gregorian calendar was introduced later than 4 October 1 ...

Gregorian Calendar: Encyclopedia - Intercalation

The solar year does not have whole number of days, but a calendar year must have a whole number of days. The only way to reconcile the two is to vary the number of days in the calendar year. In many calendars, this is done by adding to a common year of 365 days, an extra day (leap day or intercalary day): this makes a leap year of 366 days. In the Gregorian calendar, the intercalary day is February 29. The solar year does not have a whole number of lunar months either, so a lunisolar calendar must have a variable ...

Gregorian Calendar: Encyclopedia - Sabbat neopaganism

In the Wiccan form of neopaganism, a Sabbat is one of the eight major seasonal festivals which make up the Wheel of the Year. These include the solstices and equinoxes, and four additional festivals sometimes referred to as the "cross-quarter days". The word derives from Old English "sabat", from Old French "sabbat", from Latin "sabbatum", from Greek "sabbaton" (or sa`baton), from Hebrew "shabbat" - to cease or rest - the same roots as "Sabbath (christian)" or "Shabbat (judaism)". See also "sabbath". The word appears in the wri ...

Gregorian Calendar: Encyclopedia - Computus

Computus (Latin for computation) is the calculation of the date of Easter in the Christian calendar. The name has been used for this procedure since the early Middle Ages, as it was one of the most important computations of the age. The canonical rule is that Easter Sunday is the first Sunday after the 14th day of the lunar month (the nominal full moon) that falls on or after 21 March (nominally the day of the vernal equinox). For determining the feast, Christian churches settled on a method to define a reckoned "ecclesiastic" ...

Gregorian Calendar: Encyclopedia - Month

The month is a unit of time, used with calendars, which is approximately as long as some natural period related to the motion of the Moon. The traditional concept arose with the cycle of moon phases; such months (lunations) are synodic months and last ~29.53 days. From excavated tally sticks, researchers have deduced that people counted days in relation to the Moon's phases as early as the Paleolithic age. Synodic months are still the basis of many calendars.

A calendar is a system for naming periods of time, typically days. These names are known as calendar dates. The dates may be based on the perceived motion of astronomical objects. A calendar is also a physical device (often paper) that illustrates the system (for example, a desktop calendar) — this is the most common usage of the word. As a subset, 'calendar' is also used to denote a list of particular set of planned events (for example, court calendar). Calendar - Calendar systems. Including:

Gregorian Calendar: Encyclopedia II - Gregorian calendar - Accuracy

The Gregorian calendar improves the approximation made by the Julian calendar by skipping 3 Julian leap days in every 400 years, giving an average year of 365.2425 mean solar days long, which has an error of about 1 day per 3300 years with respect to the mean tropical year of 365.2422 days but less than half this error with respect to the vernal equinox year of 365.2424 days. Both are substantially more accurate than the 1 day in 128 years error of ...
