Gregorian Calendar
The Gregorian calendar is the calendar used in most parts of the world. It was introduced in October 1582 by Pope Gregory XIII as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years differently so as to make the average calendar year 365.2425 days long, more closely approximating the 365.2422-day 'tropical' or 'solar' year that is determined by the Earth's revolution around the Sun. The rule for leap years is: There were two reasons to establish the Gregorian calendar. First, the Julian calendar assumed incorrectly that the average solar year is exactly 365.25 days long, an overestimate of a little under one day per century, and thus has a leap year every four years without exception. The Gregorian reform shortened the average (calendar) year by 0.0075 days to stop the drift of the calendar with respect to the equinoxes.See Wikisource English translation of the (Latin) 1582 papal bull '' Inter gravissimas''.

Calendar
A calendar is a system of organizing days. This is done by giving names to periods of time, typically days, weeks, months and years. A date is the designation of a single and specific day within such a system. A calendar is also a physical record (often paper) of such a system. A calendar can also mean a list of planned events, such as a court calendar or a partly or fully chronological list of documents, such as a calendar of wills. Periods in a calendar (such as years and months) are usually, though not necessarily, synchronized with the cycle of the sun or the moon. The most common type of pre-modern calendar was the lunisolar calendar, a lunar calendar that occasionally adds one intercalary month to remain synchronized with the solar year over the long term. Etymology The term ''calendar'' is taken from , the term for the first day of the month in the Roman calendar, related to the verb 'to call out', referring to the "calling" of the new moon when it was fir ...

List Of Adoption Dates Of The Gregorian Calendar By Country
This is a list of adoption dates of the Gregorian calendar by country. For explanation, see the article about the Gregorian calendar. Except where stated otherwise, the transition was a move by the civil authorities from the Julian to the Gregorian calendar. In religious sources it could be that the Julian calendar was used for a longer period of time, in particular by Protestant and Eastern Orthodox churches. The historic area does not necessarily match the present-day area or country. The column 'Present country' only provides a logic search entry. With a few exceptions, the former colonies of European powers are not shown separately. There are only four countries which have not adopted the Gregorian calendar: Ethiopia (Ethiopian calendar), Nepal (Vikram Samvat and Nepal Sambat), Iran and Afghanistan (Solar Hijri calendar).

Mysterii Paschalis
''Mysterii Paschalis'' is an apostolic letter issued '' motu proprio'' (that is, "of his own accord") by Pope Paul VI on 14 February 1969. It reorganized the liturgical year of the Roman Rite and revised the liturgical celebrations of Jesus Christ and the saints in the General Roman Calendar. It promulgated the General Roman Calendar of 1969. Content of the apostolic letter By this document, Pope Paul VI implemented the Second Vatican Council's norms for restoring the liturgical year and "approve by Our apostolic authority ��the new Roman Universal Calendar ��and likewise the general norms concerning the arrangement of the liturgical year". The new norms became effective on 1 January 1970. Liturgical year The principles indicated in the document ''Universal Norms for the Liturgical Year'' were declared applicable both to the Roman Rite and to all other liturgical rites, while the practical norms were to be understood as intended for the Roman Rite alone except ...

29 February
February 29, also known as leap day or leap year day, is a date added to leap years. A leap day is added in various solar calendars (calendars based on the Earth's revolution around the Sun), including the Gregorian calendar standard in most of the world. Lunisolar calendars (whose months are based on the phases of the Moon) instead add a leap or intercalary month. It is the 60th day of a leap year in the Gregorian calendar, and 306 days remain until the end of the leap year. It is also the last day of February on leap years. It is also the last day of meteorological winter in Northern Hemisphere and the last day of meteorological summer in the Southern Hemisphere on leap years. Events Pre-1600 * 1504 – Christopher Columbus uses his knowledge of a lunar eclipse that night to convince Jamaican natives to provide him with supplies. 1601–1900 * 1644 – Abel Tasman's second Pacific voyage begins as he leaves Batavia in command of three ships. * 1704 – In ...

Bissextus
Bissext, or bissextus () is the 'leap day' which is added to the Julian calendar and the Gregorian calendar every fourth year to compensate for the six-hour difference in length between the common 365-day year and the actual length of the solar year. (The Gregorian calendar omits this leap day in years evenly divisible by 100, unless they are divisible by 400) In the Julian calendar, 24 February i.e. the 6th day before the calends (1st) of March, counting backwards inclusively in the Roman style (1/3, 28/2, 27/2, 26/2, 25/2, 24/2) was doubled in a leap year. Consequently the , or sixth before the calends, the or "second sixth," was ''also'' 24 February. In modern usage, with the exception of some ecclesiastical calendars, this intercalary day is added for convenience at the end of the month of February, as 29 February, and years in which February has 29 days are called "bissextile," or leap years.

Solar Calendar
A solar calendar is a calendar whose dates indicate the season or almost equivalently the apparent position of the Sun relative to the stars. The Gregorian calendar, widely accepted as a standard in the world, is an example of a solar calendar. The main other type of calendar is a lunar calendar, whose months correspond to cycles of Moon phases. The months of the Gregorian calendar do not correspond to cycles of the Moon phase. The Egyptians appear to have been the first to develop a solar calendar, using as a fixed point the annual sunrise reappearance of the Dog Star—Sirius, or Sothis—in the eastern sky, which coincided with the annual flooding of the Nile River. They constructed a calendar of 365 days, consisting of 12 months of 30 days each, with 5 days added at the year’s end. The Egyptians’ failure to account for the extra fraction of a day, however, caused their calendar to drift gradually into error. Examples The oldest solar calendars include the Julian calendar ...

Civil Calendar
The civil calendar is the calendar, or possibly one of several calendars, used within a country for civil, official, or administrative purposes. The civil calendar is almost always used for general purposes by people and private organizations. The most widespread civil calendar and ''de facto'' international standard is the Gregorian calendar. Although that calendar is associated with the Catholic Church and the papacy, it has been adopted, as a matter of convenience, by many secular and non-Christian countries although some countries use other calendars. Civil calendars worldwide 168 of the world's countries use the Gregorian calendar as their sole civil calendar as of 2021.{{Cite web, url=https://www.worldatlas.com/articles/countries-that-use-their-own-calendar.html, title=Countries That Use Their Own Calendar, website=WorldAtlas, language=en, access-date=2020-03-07 Most non-Christian countries have adopted it as a result of colonization, with some cases of voluntary adopti ...

Old Style And New Style
Old Style (O.S.) and New Style (N.S.) indicate dating systems before and after a calendar change, respectively. Usually, this is the change from the Julian calendar to the Gregorian calendar as enacted in various European countries between 1582 and 1923. In England, Wales, Ireland and Britain's American colonies, there were two calendar changes, both in 1752. The first adjusted the start of a new year from Lady Day (25 March) to 1 January (which Scotland had done from 1600), while the second discarded the Julian calendar in favour of the Gregorian calendar, removing 11 days from the September 1752 calendar to do so.Spathaky, MikOld Style and New Style Dates and the change to the Gregorian Calendar "Before 1752, parish registers, in addition to a new year heading after 24th March showing, for example '1733', had another heading at the end of the following December indicating '1733/4'.

Dual Dating
Dual dating is the practice, in historical materials, to indicate some dates with what appears to be duplicate, or excessive digits, sometimes separated by a hyphen, a slash or are placed one above the other. The need for dual dating arose from the transition from an older calendar to a newer one. For example, in "10/21 February 1750/51", the dual day of the month is due to the correction for excess leap years in the Julian calendar by the Gregorian calendar, and the dual year is due to some countries beginning their numbered year on 1 January while others were still using another date. Another method used is to give a date of an event according to one calendar, followed in parentheses by the date of the same event in the other, suffixing an indicator to each to specify which reference calendar applies.

Eastern Orthodoxy
Eastern Orthodoxy, also known as Eastern Orthodox Christianity, is one of the three main branches of Chalcedonian Christianity, alongside Catholicism and Protestantism. Like the Pentarchy of the first millennium, the mainstream (or " canonical") Eastern Orthodox Church is organised into autocephalous churches independent from each other. In the 21st century, the number of mainstream autocephalous churches is seventeen; there also exist autocephalous churches unrecognized by those mainstream ones. Autocephalous churches choose their own primate. Autocephalous churches can have jurisdiction (authority) over other churches, some of which have the status of " autonomous" which means they have more autonomy than simple eparchies. Many of these jurisdictions correspond to the territories of one or more modern states; the Patriarchate of Moscow, for example, corresponds to Russia and some of the other post-Soviet states. They can also include metropolises, bishoprics, pari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
