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 ...

Tang Dynasty
The Tang dynasty (, ; zh, t= ), or Tang Empire, was an Dynasties in Chinese history, imperial dynasty of China that ruled from 618 to 907 AD, with an Zhou dynasty (690–705), interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. Historians generally regard the Tang as a high point in Chinese civilization, and a Golden age (metaphor), golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivaled that of the Han dynasty. The House of Li, Lǐ family () founded the dynasty, seizing power during the decline and collapse of the Sui Empire and inaugurating a period of progress and stability in the first half of the dynasty's rule. The dynasty was formally interrupted during 690–705 when Empress Wu Zetian seized the throne, proclaiming the Zhou dynasty (690–705), Wu Zhou dynasty and becoming the only legitimate Chinese empress regnant. The devast ...

Five Dynasties And Ten Kingdoms
The Five Dynasties and Ten Kingdoms period (), from 907 to 979, was an era of political upheaval and division in 10th-century Imperial China. Five dynastic states quickly succeeded one another in the Central Plain, and more than a dozen concurrent dynastic states were established elsewhere, mainly in South China. It was a prolonged period of multiple political divisions in Chinese imperial history. Traditionally, the era is seen as beginning with the fall of the Tang dynasty in 907 and reaching its climax with the founding of the Song dynasty in 960. In the following 19 years, Song gradually subdued the remaining states in South China, but the Liao dynasty still remained in China's north (eventually succeeded by the Jin dynasty), and the Western Xia was eventually established in China's northwest. Many states had been ''de facto'' independent long before 907 as the Tang dynasty's control over its officials waned, but the key event was their recognition as sovereign by foreig ...

Japanese Calendar
Japanese calendar types have included a range of official and unofficial systems. At present, Japan uses the Gregorian calendar together with year designations stating the year of the reign of the current Emperor. The written form starts with the year, then the month and finally the day, coinciding with the ISO 8601 standard. For example, February 16, 2003 can be written as either 2003年2月16日 or 平成15年2月16日 (the latter following the regnal year system). 年 reads ''nen'' and means "year", 月 reads ''gatsu'' or 「がつ」and means "month" and finally 日 (usually) reads ''nichi'' (its pronunciation depends on the number that precedes it, see below) and means "day". Prior to the introduction of the Gregorian calendar in 1873, the reference calendar was based on the lunisolar Chinese calendar. History The lunisolar Chinese calendar was introduced to Japan via Korea in the middle of the sixth century. After that, Japan calculated its calendar using various Chine ...

Sexagenary Cycle
The sexagenary cycle, also known as the Stems-and-Branches or ganzhi ( zh, 干支, gānzhī), is a cycle of sixty terms, each corresponding to one year, thus a total of sixty years for one cycle, historically used for recording time in China and the rest of the East Asian cultural sphere. It appears as a means of recording days in the first Chinese written texts, the Shang dynasty, Shang oracle bones of the late second millennium BC. Its use to record years began around the middle of the 3rd century BC. The cycle and its variations have been an important part of the traditional calendrical systems in Chinese-influenced Asian states and territories, particularly those of Japanese calendar, Japan, Korean calendar, Korea, and Vietnamese calendar, Vietnam, with the old Chinese system still in use in Taiwanese calendar, Taiwan, and to a lesser extent, in Mainland China. This traditional method of numbering days and years no longer has any significant role in modern Chinese time-keeping ...

The library is similar in purpose and scope to the United States Library of Congress. The National Diet Library (NDL) consists of two main facilities in Tokyo and Kyoto, and several other branch libraries throughout Japan. History The National Diet Library is the successor of three separate libraries: the library of the House of Peers, the library of the House of Representatives, both of which were established at the creation of Japan's Imperial Diet in 1890; and the Imperial Library, which had been established in 1872 under the jurisdiction of the Ministry of Education. The Diet's power in prewar Japan was limited, and its need for information was "correspondingly small".
