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] |
Shibukawa Shunkai
born as Yasui Santetsu (), later called Motoi Santetsu (), was a Japanese scholar, go player and the first official astronomer appointed of the Edo period. He revised the Chinese lunisolar calendar at the shogunate request, drawing up the Jōkyō calendar which was issued in 1684 during the Jōkyō era. In 1702, he changed his name to ''Shibukawa Sukezaemon Shunkai'' and retired by 1711. As a go player, he was affiliated with the Yasui house, calling himself initially (after his father) Yasui Santetsu II. He is mentioned as a Tengen player in Yamashita Keigo 's book: ''Challenging Tengen''. Shibukawa Shunkai (as Yasui Santetsu) is the central character in the 2012 film '' Tenchi: The Samurai Astronomer'' by Yōjirō Takita Yōjirō Takita (滝田 洋二郎 ''Takita Yōjirō'', born December 4, 1955) is a Japanese filmmaker.

Senmyō Calendar
The Xuanming calendar (宣明历), also known as ''Senmyō-reki'' or ''Senmei-reki'' in its Japanese version, was a Chinese lunisolar calendar. It was used in China during the 9th century as well as in the Koryo kingdom in Korea; in Japan it remained in use from the late-9th century to the late-17th century. In China, the Xuanming calendar was the penultimate calendar to be used in the Tang dynasty. In 893, it was replaced by the Chongxuan calendar (崇玄曆), which was used to the end of the Tang dynasty and beyond. History China The Xuanming calendar was one of several calendars developed during the Tang dynasty. It was implemented in 822 and was used until 892, a period of 71 years. In 893, it was replaced by the Chongxuan calendar (崇玄曆), which was used to the end of the Tang dynasty and into the subsequent Five Dynasties and Ten Kingdoms period. Japan The calendar was imported into Japan in 859. The earliest record of this calendar being used in Japan is in the 8th mon ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Diet Library
The is the national library of Japan and among the largest libraries in the world. It was established in 1948 for the purpose of assisting members of the in researching matters of public policy. 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". The original Diet libraries "never developed either the collections or the services which might have made t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of Science And Technology In Japan
This is the history of science and technology in modern Japan. Science In the natural sciences, the number of Japanese winners of the Nobel Prize has been second only to the United States in the 21st century, for contributions made in the 20th century. On the list of countries by research and development spending, Japan is third on the list, behind the United States and China. Chemistry ;Frontier Molecular Orbital Theory In 1952, Kenichi Fukui published a paper in the ''Journal of Chemical Physics'' titled "A molecular theory of reactivity in aromatic hydrocarbons." He later received the 1981 Nobel Prize in Chemistry for his investigations into the mechanisms of chemical reactions, with his prize-winning work focused on the role of frontier orbitals in chemical reactions, specifically that molecules share loosely bonded electrons which occupy the frontier orbitals, that is the Highest Occupied Molecular Orbital (HOMO) and the Lowest Unoccupied Molecular Orbital (LUMO). ;Chira ...
