The 15th century was the century which spans the Julian years 1401 to 1500. In Europe, the 15th century is seen as the bridge between the Late Middle Ages, the Early Renaissance, the Early modern period. Many technological and cultural developments of the 15th century can in retrospect be seen as heralding the "European miracle" of the following centuries. In religious history, the Roman Papacy was split in two parts in Europe for decades, until the Council of Constance; the division of the Catholic Church and the unrest associated with the Hussite movement would become factors in the rise of the Protestant Reformation in the following century. Constantinople, in what is today Turkey the capital of the Christian Byzantine Empire, falls to the emerging Muslim Ottoman Turks, marking the end of the tremendously influential Byzantine Empire and, for some historians, the end of the Middle Ages; the event forced Western Europeans to find a new trade route, adding further momentum to what was the beginning of the Age of Discovery, which would lead to the global mapping of the world.
Explorations by the Portuguese and Spanish led to European sightings of the Americas and the sea passage along Cape of Good Hope to India, in the last decade of the century. These expeditions ushered in the era of the Portuguese and Spanish colonial empires; the fall of Constantinople led to the migration of Greek scholars and texts to Italy, while Johannes Gutenberg's invention of the mechanical movable type began the Printing Press. These two events played key roles in the development of the Renaissance; the Spanish Reconquista leads to the final fall of the Emirate of Granada by the end of the century, ending over seven centuries of Muslim rule and returning Spain back to Christian rulers. The Hundred Years' War end with a decisive French victory over the English in the Battle of Castillon. Financial troubles in England following the conflict results in the Wars of the Roses, a series of dynastic wars for the throne of England; the conflicts end with the defeat of Richard III by Henry VII at the Battle of Bosworth Field, establishing the Tudor dynasty in the part of the century.
In Asia, under the rule of the Yongle Emperor, who built the Forbidden City and commanded Zheng He to explore the world overseas, the Ming Dynasty's territory reached its pinnacle. Tamerlane established a major empire in the Middle East and Central Asia, in order to revive the Mongol Empire. In Africa, the spread of Islam leads to the destruction of the Christian kingdoms of Nubia, by the end of the century leaving only Alodia; the vast Mali Empire teeters on the brink of collapse, under pressure from the rising Songhai Empire.

The Byzantine calendar called "Creation Era of Constantinople" or "Era of the World", was the calendar used by the Eastern Orthodox Church from c. 691 to 1728 in the Ecumenical Patriarchate. It was the official calendar of the Byzantine Empire from 988 to 1453, of Kievan Rus' and Russia from c. 988 to 1700. Since "Byzantine" is a historiographical term, the original name uses the noun "Roman" as it was how the Eastern Roman Empire continued calling itself; the calendar was based on the Julian calendar, except that the year started on 1 September and the year number used an Anno Mundi epoch derived from the Septuagint version of the Bible. It placed the date of creation at 5509 years before the Incarnation, was characterized by a certain tendency, a tradition among Jews and early Christians to number the years from the calculated foundation of the world, its Year One, marking the supposed date of creation, was September 1, 5509 BC, to August 31, 5508 BC. It is not known when; the first appearance of the term is in the treatise of a certain "monk and priest", who mentions all the main variants of the "World Era" in his work.
Georgios argues that the main advantage of the World era is the common starting point of the astronomical lunar and solar cycles, of the cycle of indictions, the usual dating system in Byzantium since the 6th century. He already regards it as the most convenient for the Easter computus. Complex calculations of the 19-year lunar and 28-year solar cycles within this world era allowed scholars to discover the cosmic significance of certain historical dates, such as the birth or the crucifixion of Jesus; this date underwent minor revisions before being finalized in the mid-7th century, although its precursors were developed c. AD 412. By the second half of the 7th century, the Creation Era was known in Western Europe, at least in Great Britain. By the late 10th century around AD 988, when the era appears in use on official government records, a unified system was recognized across the Eastern Roman world; the era was calculated as starting on September 1, Jesus was thought to have been born in the year 5509 since the creation of the world.
Historical time was thus calculated from the creation, not from Christ's birth, as in the west after the Anno Domini system was adopted between 6th and 9th centuries. The Eastern Church avoided the use of the Anno Domini system of Dionysius Exiguus, since the date of Christ's birth was debated in Constantinople as late as the 14th century. Otherwise the Byzantine calendar was identical to the Julian Calendar except that: the names of the months were transcribed from Latin into Greek; the leap day of the Byzantine calendar was obtained in an identical manner to the bissextile day of the original Roman version of the Julian calendar, by doubling the sixth day before the calends of March, i.e. by doubling 24 February. The Byzantine World Era was replaced in the Orthodox Church by the Christian Era, utilized by Patriarch Theophanes I Karykes in 1597, afterwards by Patriarch Cyril Lucaris in 1626, formally established by the Church in 1728. Meanwhile, as Russia received Orthodox Christianity from Byzantium, she inherited the Orthodox Calendar based on the Byzantine Era.
After the collapse of the Byzantine Empire in 1453, the era continued to be used by Russia, which witnessed millennialist movements in Moscow in AD 1492. It was only in AD 1700 that the Byzantine World Era in Russia was changed to the Julian Calendar by Peter the Great, it still forms the basis of traditional Orthodox calendars up to today. September AD 2000 began the year 7509 AM; the earliest extant Christian writings on the age of the world according to the Biblical chronology are by Theophilus, the sixth bishop of Antioch from the Apostles, in his apologetic work To Autolycus, by Julius Africanus in his Five Books of Chronology. Both of these early Christian writers, following the Septuagint version of the Old Testament, determined the age of the world to have been about 5,530 years at the birth of Christ. Ben Zion Wacholder points out that the writings of the Church Fathers on this subject are of vital significance, in that through the Christian chronographers a window to the earlier Hellenistic biblical chronographers is preserved: An immense intellectual effort was expended during the Hellenistic period by both Jews and pagans to date creation, the flood, building of the Temple...

BT Group plc is a British multinational telecommunications holding company headquartered in London, United Kingdom. It has operations in around 180 countries and is the largest provider of fixed-line and mobile services in the UK, provides subscription television and IT services. BT's origins date back to the founding of the Electric Telegraph Company in 1846 which developed a nationwide communications network. In 1912, the General Post Office, a government department, became the monopoly telecoms supplier in the United Kingdom; the Post Office Act of 1969 led to the GPO becoming a public corporation. British Telecommunications, trading as British Telecom, was formed in 1980, became independent of the Post Office in 1981. British Telecommunications was privatised in 1984, becoming British Telecommunications plc, with some 50 percent of its shares sold to investors; the Government sold its remaining stake in further share sales in 1991 and 1993. BT is a Royal Warrant holder of the British Royal Family and has a primary listing on the London Stock Exchange, a secondary listing on the New York Stock Exchange, is a constituent of the FTSE 100 Index.
BT controls a number of large subsidiaries. BT Global Services division supplies telecoms services to corporate and government customers worldwide, its BT Consumer division supplies telephony and subscription television services in Great Britain to around 18 million customers. A number of owned telegraph companies operated in Britain from 1846 onwards. Among them were: The Electric Telegraph Company British and Irish Magnetic Telegraph Company British Telegraph Company London District Telegraph Company and the United Kingdom Telegraph CompanyThe Telegraph Act 1868 passed the control of all these to the newly formed GPO's Postal Telegraphs Department. With the invention of the telephone by Alexander Graham Bell in 1876 the GPO began to provide telephone services from some of its telegraph exchanges. In 1882 the Postmaster-General, Henry Fawcett started to issue licences to operate a telephone service to private businesses and the telephone system grew under the GPO in some areas and private ownership in others.
The GPO's main competitor, the National Telephone Company, emerged in this market by absorbing other private telephone companies, prior to its absorption into the GPO in 1912. The trunk network was unified under GPO control in 1896 and the local distribution network in 1912. A few municipally owned services remained outside of GPO control; these were Kingston upon Hull and Guernsey. Hull still retains an independent operator, Kingston Communications, though it is no longer municipally controlled. In 1969 the GPO, a government department, became the Post Office, a nationalised industry separate from government. Post Office Telecommunications was one of the divisions; the British Telecom brand was introduced in 1980. On 1 October 1981, this became the official name of Post Office Telecommunications, which became a state-owned corporation independent of the Post Office under the provisions of the British Telecommunications Act 1981. In 1982 BT's monopoly on telecommunications was broken with the granting of a licence to Mercury Communications.
On 19 July 1982, the Government announced its intention to sell shares in British Telecom to the public. On 1 April 1984, British Telecommunications was incorporated as a public limited company in anticipation of the passing of the Telecommunications Bill; this Bill received Royal Assent on 12 April, the transfer to British Telecommunications plc from British Telecom as a statutory corporation of its business, its property, its rights and liabilities took place on 6 August 1984. All shares in the new plc were owned by the Government. In November 1984, 50.2 % of the new company was offered for sale to employees. Shares were listed in London, New York, Toronto and the first day of trading on was 3 December 1984; the Government sold half its remaining interest in December 1991 and the other half in July 1993. In July 1997, the new Labour Government relinquished its Special Share, retained at the time of the flotation, which had given it the power to block a takeover of the company, to appoint two non-executive directors to the Board.
The company changed its trading name to "BT" on 2 April 1991. In 1996 Peter Bonfield was appointed CEO and Chairman of the Executive Committee, promising a "rollercoaster ride". In the 1990s, BT entered the Irish telecommunications market through a joint venture with the Electricity Supply Board, the Irish state owned power provider; this venture, entitled Ocean, found its main success through the launch of Ireland's first subscription-free dial-up ISP, oceanfree.net. As a telecoms company it found much less success targeting corporate customers. BT acquired 100% of this venture in 1999. In June 1994 BT and MCI Communications launched Concert Communications Services, a $1 billion joint venture between the two companies, its aim was to build a network which would provide easy global connectivity to multinational corporations. This alliance progressed further on 3 November 1996 when the two companies announced that they had agreed to a merger, creating a global telecommunications company called Concert plc.
The proposal gained approval from the European Commission, the US Department of Justice, the US Federal Communications Commission and looked set to proceed. However, in light of pressure from investors reacting to the slide in BT's share price on the London Stock Exchange, BT reduced its bid price for MCI, releasing MCI from its exclusivity clause and allowing it to speak to other interested parties. On 1 October 1997, Worldcom made a rival bid for MCI which wa
The Rabbit is the fourth of the 12-year cycle of animals which appear in the Chinese zodiac related to the Chinese calendar. The Year of the Rabbit is associated with the Earthly Branch symbol 卯. In the Vietnamese zodiac and the Gurung zodiac, the cat takes the place of the Rabbit. People born within these date ranges can be said to have been born in the "Year of the Rabbit", while bearing the following elemental sign: Rabbit
The Hebrew or Jewish calendar is a lunisolar calendar used today predominantly for Jewish religious observances. It determines the dates for Jewish holidays and the appropriate public reading of Torah portions and daily Psalm readings, among many ceremonial uses. In Israel, it is used for religious purposes, provides a time frame for agriculture and is an official calendar for civil purposes, although the latter usage has been declining in favor of the Gregorian calendar; the present Hebrew calendar is the product including a Babylonian influence. Until the Tannaitic period, the calendar employed a new crescent moon, with an additional month added every two or three years to correct for the difference between twelve lunar months and the solar year; the year in which it was added was based on observation of natural agriculture-related events in ancient Israel. Through the Amoraic period and into the Geonic period, this system was displaced by the mathematical rules used today; the principles and rules were codified by Maimonides in the Mishneh Torah in the 12th century.
Maimonides' work replaced counting "years since the destruction of the Temple" with the modern creation-era Anno Mundi. The Hebrew lunar year is about eleven days shorter than the solar year and uses the 19-year Metonic cycle to bring it into line with the solar year, with the addition of an intercalary month every two or three years, for a total of seven times per 19 years. With this intercalation, the average Hebrew calendar year is longer by about 6 minutes and 40 seconds than the current mean tropical year, so that every 217 years the Hebrew calendar will fall a day behind the current mean tropical year; the era used. As with Anno Domini, the words or abbreviation for Anno Mundi for the era should properly precede the date rather than follow it. AM 5779 began at sunset on 9 September 2018 and will end at sunset on 29 September 2019; the Jewish day is of no fixed length. The Jewish day is modeled on the reference to "...there was evening and there was morning..." in the creation account in the first chapter of Genesis.
Based on the classic rabbinic interpretation of this text, a day in the rabbinic Hebrew calendar runs from sunset to the next sunset. Halachically, a day ends and a new one starts when three stars are visible in the sky; the time between true sunset and the time when the three stars are visible is known as'bein hashmashot', there are differences of opinion as to which day it falls into for some uses. This may be relevant, for example, in determining the date of birth of a child born during that gap. There is no clock in the Jewish scheme. Though the civil clock, including the one in use in Israel, incorporates local adoptions of various conventions such as time zones, standard times and daylight saving, these have no place in the Jewish scheme; the civil clock is used only as a reference point – in expressions such as: "Shabbat starts at...". The steady progression of sunset around the world and seasonal changes results in gradual civil time changes from one day to the next based on observable astronomical phenomena and not on man-made laws and conventions.
In Judaism, an hour is defined as 1/12 of the time from sunrise to sunset, so, during the winter, an hour can be much less than 60 minutes, during the summer, it can be much more than 60 minutes. This proportional hour is known as a sha'ah z'manit. A Jewish hour is divided into parts. A part is 1/18 minute; the ultimate ancestor of the helek was a small Babylonian time period called a barleycorn, itself equal to 1/72 of a Babylonian time degree. These measures are not used for everyday purposes. Instead of the international date line convention, there are varying opinions as to where the day changes. One opinion uses the antimeridian of Jerusalem. Other opinions exist as well; the weekdays proceed to Saturday, Shabbat. Since some calculations use division, a remainder of 0 signifies Saturday. While calculations of days and years are based on fixed hours equal to 1/24 of a day, the beginning of each halachic day is based on the local time of sunset; the end of the Shabbat and other Jewish holidays is based on nightfall which occurs some amount of time 42 to 72 minutes, after sunset.
According to Maimonides, nightfall occurs. By the 17th century, this had become three-second-magnitude stars; the modern definition is when the center of the sun is 7° below the geometric horizon, somewhat than civil twilight at 6°. The beginning of the daytime portion of each day is determined both by sunrise. Most halachic times are based on some combination of these four times and vary from day to day throughout the year and vary depending on location; the daytime hours are divided into Sha'oth Zemaniyoth or "Halachic hours" by taking the time between sunrise and sunset or between dawn and nightfall and dividing it into 12 equal hours. The nighttime hours are s
