Chongzhen Calendar
The Chongzhen calendar () or Shixian calendar () was the final lunisolar Chinese calendar. It was developed by the Jesuit scholars Johann Schreck and Johann Adam Schall von Bell with Xu Guangqi from 1624 to 1644, and was dedicated to the Chongzhen Emperor. When he died a year after it was released, it was propagated in the first year of the Qing dynasty by the Shunzhi Emperor, who changed its name to Shíxiàn calendar. The calendar was used from the early Qing period into the modern era. The main changes introduced by the calendar are: * Replacement of the original "平气法" solar term system (based on dividing a tropical year equally) with one based on the ecliptic longitude The ecliptic coordinate system is a celestial coordinate system commonly used for representing the apparent positions, orbits, and pole orientations of Solar System objects. Because most planets (except Mercury) and many small Solar System bodi ... of the sun ("定气法"). * Placement of intercalary m ...

Lunisolar Calendar
A lunisolar calendar is a calendar in many cultures, combining lunar calendars and solar calendars. The date of Lunisolar calendars therefore indicates both the Moon phase and the time of the solar year, that is the position of the Sun in the Earth's sky. If the sidereal year (such as in a sidereal solar calendar) is used instead of the solar year, then the calendar will predict the constellation near which the full moon may occur. As with all calendars which divide the year into months there is an additional requirement that the year have a whole number of months. In this case ordinary years consist of twelve months but every second or third year is an embolismic month, embolismic year, which adds a thirteenth Intercalation (timekeeping), intercalary, embolismic, or leap month. Their months are based on the regular cycle of the Moon's lunar phase, phases. So lunisolar calendars are lunar calendars with – in contrast to them – additional Intercalation (timekeeping), inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Calendar
The traditional Chinese calendar (also known as the Agricultural Calendar ��曆; 农历; ''Nónglì''; 'farming calendar' Former Calendar ��曆; 旧历; ''Jiùlì'' Traditional Calendar ��曆; 老历; ''Lǎolì'', is a lunisolar calendar which identifies years, months, and days according to astronomical phenomena. In China, it is defined by the Chinese national standard GB/T 33661–2017, "Calculation and Promulgation of the Chinese Calendar", issued by the Standardization Administration of China on May 12, 2017. Although modern-day China uses the Gregorian calendar, the traditional Chinese calendar governs holidays, such as the Chinese New Year and Lantern Festival, in both China and overseas Chinese communities. It also provides the traditional Chinese nomenclature of dates within a year which people use to select auspicious days for weddings, funerals, moving or starting a business. The evening state-run news program ''Xinwen Lianbo'' in the P.R.C. continues to anno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johann Adam Schall Von Bell
Johann Adam Schall von Bell (1 May 1591 – 15 August 1666) was a German Jesuit, astronomer and instrument-maker. He spent most of his life as a missionary in China (where he is remembered as "Tang Ruowang") and became an adviser to the Shunzhi Emperor of the Qing dynasty. Life Schall von Bell was born to noble parents in Cologne or nearby Lüftelberg (today part of Meckenheim) in the Holy Roman Empire.

Qing Dynasty
The Qing dynasty ( ), officially the Great Qing,, was a Manchu-led imperial dynasty of China and the last orthodox dynasty in Chinese history. It emerged from the Later Jin dynasty founded by the Jianzhou Jurchens, a Tungusic-speaking ethnic group who unified other Jurchen tribes to form a new "Manchu" ethnic identity. The dynasty was officially proclaimed in 1636 in Manchuria (modern-day Northeast China and Outer Manchuria). It seized control of Beijing in 1644, then later expanded its rule over the whole of China proper and Taiwan, and finally expanded into Inner Asia. The dynasty lasted until 1912 when it was overthrown in the Xinhai Revolution. In orthodox Chinese historiography, the Qing dynasty was preceded by the Ming dynasty and succeeded by the Republic of China. The multiethnic Qing dynasty lasted for almost three centuries and assembled the territorial base for modern China. It was the largest imperial dynasty in the history of China and in 1790 the f ...

Shunzhi Emperor
The Shunzhi Emperor (15 March 1638 – 5 February 1661) was the second Emperor of China, emperor of the Qing dynasty of China, and the first Qing emperor to rule over China proper, reigning from 1644 to 1661. A Deliberative Council of Princes and Ministers, committee of Manchu princes chose him to succeed his father, Hong Taiji (1592–1643), in September 1643, when he was five years old. The princes also appointed two co-regents: Dorgon (1612–1650), the 14th son of the Qing dynasty's founder Nurhaci (1559–1626), and Jirgalang (1599–1655), one of Nurhaci's nephews, both of whom were members of the Aisin Gioro, Qing imperial clan.

Solar Term
A solar term is any of twenty-four periods in traditional Chinese lunisolar calendars that matches a particular astronomical event or signifies some natural phenomenon. The points are spaced 15° apart along the ecliptic and are used by lunisolar calendars to stay synchronized with the seasons, which is crucial for agrarian societies. The solar terms are also used to calculate intercalary months; which month is repeated depends on the position of the sun at the time. According to the '' Book of Documents'', the first determined term was Dongzhi (Winter Solstice) by Dan, the Duke of Zhou, while he was trying to locate the geological center of the Western Zhou dynasty, by measuring the length of the sun's shadow on an ancient timekeeper instrument named Tu Gui (土圭). Then four terms of seasons were set, which were soon evolved as eight terms; until 104 BC in the book Taichu Calendar, the entire twenty-four solar terms were officially included in the Chinese calendar.

Ecliptic Longitude
The ecliptic coordinate system is a celestial coordinate system commonly used for representing the apparent positions, orbits, and pole orientations of Solar System objects. Because most planets (except Mercury) and many small Solar System bodies have orbits with only slight inclinations to the ecliptic, using it as the fundamental plane is convenient. The system's origin can be the center of either the Sun or Earth, its primary direction is towards the vernal (March) equinox, and it has a right-hand convention. It may be implemented in spherical or rectangular coordinates. Primary direction The celestial equator and the ecliptic are slowly moving due to perturbing forces on the Earth, therefore the orientation of the primary direction, their intersection at the Northern Hemisphere vernal equinox, is not quite fixed. A slow motion of Earth's axis, precession, causes a slow, continuous turning of the coordinate system westward about the poles of the ecliptic, complet ...
