New Year's Day
In the Gregorian calendar, New Year's Day is the first day of the calendar year, January 1, 1 January. Most solar calendars, such as the Gregorian and Julian calendars, begin the year regularly at or near the December solstice, northern winter solstice. In contrast, cultures and religions that observe a lunisolar or lunar calendar celebrate their Lunar New Year at varying points relative to the solar year. In pre-Christian Rome, under the Julian calendar, the day was dedicated to Janus, god of gateways and beginnings, for whom January is also named. From Roman times until the mid-18th century, the new year was celebrated at various stages and in various parts of Christian Europe on 25 December, on 1 March, on 25 March and on the Date of Easter, movable feast of Easter. In the present day, with most countries now using the Gregorian calendar as their civil calendar, 1 January according to Gregorian calendar is among the most celebrated of public holidays in the w ...

Gregorian Calendar
The Gregorian calendar is the calendar used in most parts of the world. It went into effect in October 1582 following the papal bull issued by Pope Gregory XIII, which introduced it as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years slightly differently to make the average calendar year 365.2425 days long rather than the Julian calendar's 365.25 days, thus more closely approximating the 365.2422-day tropical year, "tropical" or "solar" year that is determined by the Earth's revolution around the Sun. The rule for leap years is that every year divisible by four is a leap year, except for years that are divisible by 100, except in turn for years also divisible by 400. For example 1800 and 1900 were not leap years, but 2000 was. There were two reasons to establish the Gregorian calendar. First, the Julian calendar was based on the estimate that the average solar year is exactly 365.25 days long, an overestimate of a li ...

Solar Calendar
A solar calendar is a calendar whose dates indicates 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 types of calendar are lunar calendar and lunisolar 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 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 was first declared by Pope Gregory XIII to be used in Catholic countries in 1582, it has since 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. Most non-Christian countries have adopted it as a result of colonization, with some cases of voluntary adoption. Four countries have not adopted the Gregorian calendar: Afghanistan and Iran (which use the Solar Hijri calendar), Ethiopia (the Ethiopian calendar), and Nep ...

British Academy
The British Academy for the Promotion of Historical, Philosophical and Philological Studies is the United Kingdom's national academy for the humanities and the social sciences. It was established in 1902 and received its royal charter in the same year. It is now a fellowship of more than 1,000 leading scholars spanning all disciplines across the humanities and social sciences and a funding body for research projects across the United Kingdom. The academy is a self-governing and independent registered charity, based at 10–11 Carlton House Terrace in London. The British Academy is primarily funded with annual government grants. In 2022, £49.3m of its £51.7m of charitable income came from the Department for Business, Energy, and Industrial Strategy – in the same year it took in around £2.0m in trading income and £0.56m in other income. This funding is expected to continue under the new Department for Business and Trade. Purposes The academy states that it has five fundam ...

Date Of Easter
As a moveable feast, the date of Easter is determined in each year through a calculation known as – often simply ''Computus'' – or as paschalion particularly in the Eastern Orthodox Church. Easter is celebrated on the first Sunday after the Paschal full moon (a mathematical approximation of the first astronomical full moon, on or after 21 March itself a fixed approximation of the March equinox). Determining this date in advance requires a correlation between the lunar months and the tropical year, solar year, while also accounting for the month, date, and weekday of the Julian calendar, Julian or Gregorian calendar. The complexity of the algorithm arises because of the desire to associate the date of Easter with the date of the Jewish feast of Passover which, Christians believe, is when Jesus was crucified. It was originally feasible for the entire Christian Church to receive the date of Easter each year through an annual announcement by the pope. By the early third ...

Christian Europe
The terms Christendom or Christian world commonly refer to the global Christian community, Christian states, Christian-majority countries or countries in which Christianity is dominant or prevails.SeMerriam-Webster.com : dictionary, "Christendom"/ref> Following the spread of Christianity from the Levant to Europe and North Africa during the early Roman Empire, Christendom has been divided in the pre-existing Greek East and Latin West. After the Great schism of 1054, two main branches within Christianity emerged, centred around the cities of Rome (Western Christianity, whose community was called Western or Latin Christendom) and Constantinople (Eastern Christianity, whose community was called Eastern Christendom or Byzantine commonwealth). After the fall of Constantinople in 1453, Latin Christendom rose to a central role in the Western world. Following the reformation, protestantism emerged as the third main branch of Christianity in the 16th century. The history of the Chri ...

Janus
In ancient Roman religion and myth, Janus ( ; ) is the god of beginnings, gates, transitions, time, duality, doorways, passages, frames, and endings. He is usually depicted as having two faces. The month of January is named for Janus (''Ianuarius''). According to ancient Roman farmers' almanacs, Juno was mistaken as the tutelary deity of the month of January, but Juno is the tutelary deity of the month of June. Janus presided over the beginning and ending of conflict, and hence war and peace. The gates of the Temple of Janus in Rome were opened in time of war and closed to mark the arrival of peace. As a god of transitions, he had functions pertaining to birth and to journeys and exchange, and in his association with Portunus, a similar harbor and gateway god, he was concerned with travelling, trading, and shipping. Janus had no flamen or specialised priest ''( sacerdos)'' assigned to him, but the King of the Sacred Rites ''( rex sacrorum)'' himself carried out his cerem ...

Julian Calendar
The Julian calendar is a solar calendar of 365 days in every year with an additional leap day every fourth year (without exception). The Julian calendar is still used as a religious calendar in parts of the Eastern Orthodox Church and in parts of Oriental Orthodox Churches, Oriental Orthodoxy as well as by the Amazigh, Amazigh people (also known as the Berbers). The Julian calendar was proposed in 46 BC by (and takes its name from) Julius Caesar, as a reform of the earlier Roman calendar, which was largely a lunisolar calendar, lunisolar one. It took effect on , by his edict. Caesar's calendar became the predominant calendar in the Roman Empire and subsequently most of the Western world for more than 1,600 years, until 1582 when Pope Gregory XIII promulgated a revised calendar. Ancient Romans typically designated years by the names of ruling consuls; the ''Anno Domini'' system of numbering years was not devised until 525, and became widespread in Europe in the eighth cent ...

Solar Year
A tropical year or solar year (or tropical period) is the time that the Sun takes to return to the same position in the sky – as viewed from the Earth or another celestial body of the Solar System – thus completing a full cycle of astronomical seasons. For example, it is the time from vernal equinox to the next vernal equinox, or from summer solstice to the next summer solstice. It is the type of year used by tropical solar calendars. The tropical year is one type of astronomical year and particular orbital period. Another type is the sidereal year (or sidereal orbital period), which is the time it takes Earth to complete one full orbit around the Sun as measured with respect to the fixed stars, resulting in a duration of 20 minutes longer than the tropical year, because of the precession of the equinoxes. Since antiquity, astronomers have progressively refined the definition of the tropical year. The entry for "year, tropical" in the '' Astronomical Almanac Online G ...

Lunar New Year
Lunar New Year is the beginning of a new year based on lunar calendars or, informally, lunisolar calendars. Lunar calendar years begin with a new moon and have a fixed number of lunar months, usually twelve, in contrast to lunisolar calendar years which have a variable number of lunar months that periodically resynchronise with the solar year. The event is celebrated by numerous cultures in various ways at different dates. The determination of the first day of a new lunar year or lunisolar year varies by culture. Better-known lunar new year celebrations include that based on the (lunar) Islamic calendar which originated in the Middle East. Lunisolar new year celebrations include that of the (lunisolar) Hebrew calendar from same region; the (lunisolar) Chinese calendar and Tibetan calendar of East Asia; and the (lunisolar) Buddhist and Hindu calendars of South and Southeast Asia. In 2023, the United Nations General Assembly recognized the Spring Festival that coincides with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
