Aloysius Lilius
Aloysius Lilius (c. 1510 – 1576), also variously referred to as Luigi Lilio or Luigi Giglio, was an Italian doctor, astronomer, philosopher and chronologist, and also the "primary author" who provided the proposal that (after modifications) became the basis of the Gregorian Calendar reform of 1582.For name-variants and a few biographical details (including citation to a biography published in 1963) see page 206 in: A Ziggelaar (1983)"The papal bull of 1582 promulgating a reform of the calendar" pages 201–239 in G. V. Coyne (ed.), ''The Gregorian Reform of the Calendar: Proceedings of the Vatican conference to commemorate its 400th anniversary'' (Vatican City: Specola Vaticana), 1983. The crater Lilius on the Moon is named after him, as is the asteroid 2346 Lilio. In computer science, the Lilian date is the number of days since the adoption of the Gregorian calendar on 15 October 1582. Life and work Not much is known about the early life of Lilius/Lilio/Giglio. It is known t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cirò, Calabria
Cirò is a ''comune'' and town with a population of 3614 people in the province of Crotone, in Calabria, Italy. History There were Bronze Age settlements in the area and fossils have been found and are preserved for eventual exhibition in a museum to be established. The ancient Greeks had a settlement on the sea coast - rudiments of a shrine to Apollo have been found. The town on the hill had its origins before 1000 AD but it was greatly expanded after the Saracens started raiding the sea coast. Cirò (known earlier as Psicro) became an important regional center with a castle most of which was constructed between the years 1300 and 1500. Today the castle is in a rather bad shape and should be restored. The administration is attempting to obtain funds and authorisation to do so. Until around 1970 the regional court had its seat in Cirò. After the coastal town split off, much of the administrative functions were transferred there. Economy Ciro relies on the production of oil, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Moon
In astronomy, the new moon is the first lunar phase, when the Moon and Sun have the same ecliptic longitude. At this phase, the lunar disk is not visible to the naked eye, except when it is silhouetted against the Sun during a solar eclipse. The original meaning of the term 'new moon', which is still sometimes used in calendrical, non-astronomical contexts, is the first visible crescent of the Moon after conjunction with the Sun. This thin waxing crescent is briefly and faintly visible as the Moon gets lower in the western sky after sunset. The precise time and even the date of the appearance of the new moon by this definition will be influenced by the geographical location of the observer. The first crescent marks the beginning of the month in the Islamic calendar and in some lunisolar calendars such as the Hebrew calendar. In the Chinese calendar, the beginning of the month is marked by the last visible crescent of a waning Moon. The astronomical new moon occur ...

Epact
The epact ( la, epactae, from grc, ἐπακται ἡμεραι () = added days), used to be described by medieval computists as the age of a phase of the Moon in days on 22 March; in the newer Gregorian calendar, however, the epact is reckoned as the age of the ecclesiastical moon on 1 January. Its principal use is in determining the date of Easter by computistical methods. It varies (usually by 11 days) from year to year, because of the difference between the solar year of 365366 days and the lunar year of 354355 days. Lunar calendar Epacts can also be used to relate dates in the lunar calendar to dates in the common solar calendar. Solar and lunar years A solar calendar year has 365 days (366 days in leap years). A lunar calendar year has 12 lunar months which alternate between 30 and 29 days for a total of 354 days (in leap years, one of the lunar months has a day added; since a lunar year lasts a little over days, a leap year arises every second or third year rath ...

Calendar Reform
Calendar reform or calendrical reform is any significant revision of a calendar system. The term sometimes is used instead for a proposal to switch to a different calendar design. Principles The prime objective of a calendar is to unambiguously identify any day in past, present and future by a specific date in order to record or organize social, religious, commercial or administrative events. Recurring periods that contain multiple days, like weeks, months and even years, are secondary, convenient features of a calendar. Most cultures adopt a primary dating system, but different cultures have always needed to align multiple calendars with each other, because they coexisted in the same space (e.g. secular and religious groups with different demands) or had established trading relations. Once specified, a ''calendar design'' cannot be altered without becoming a new design. If a proposed design is sufficiently close to the legacy one, i.e. compatible with it, a ''reform'' of th ...

Christopher Clavius
Christopher Clavius, SJ (25 March 1538 – 6 February 1612) was a Jesuit German mathematician, head of mathematicians at the Collegio Romano, and astronomer who was a member of the Vatican commission that accepted the proposed calendar invented by Aloysius Lilius, that is known as the Gregorian calendar. Clavius would later write defences and an explanation of the reformed calendar, including an emphatic acknowledgement of Lilius' work. In his last years he was probably the most respected astronomer in Europe and his textbooks were used for astronomical education for over fifty years in and even out of Europe. Early life Little is known about Clavius' early life other than the fact that he was born in Bamberg in either 1538 or 1537. His given name is not known to any great degree of certainty—it is thought by scholars to have perhaps been ''Christoph Clau'' or ''Klau''. There are also some who think that his taken name, ''Clavius'', may be a Latinization of his original G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Perugia
University of Perugia (Italian ''Università degli Studi di Perugia'') is a public-owned university based in Perugia, Italy. It was founded in 1308, as attested by the Bull issued by Pope Clement V certifying the birth of the Studium Generale. The official seal of the university portraits Saint Herculan, one of the saint patrons, and the rampant crowned griffin, which is the city symbol: they represent the ecclesiastical and civil powers, respectively, which gave rise to the university in the Middle Ages. History One of the "free" universities of Italy, it was erected into a ''studium generale'' on September 8, 1308, by the Bull "Super specula" of Clement V. A school of arts existed by about 1200, in which medicine and law were soon taught, with a strong commitment expressed by official documents of the City Council of Perugia.
