30 February 1712
Several non-standard dates are used in calendars. Some are used sarcastically, some for scientific or mathematical purposes, and some for exceptional or fictional calendars. January 0 January 0 or 0 January is an alternative name for December 31. In an ephemeris January 0 is the day before January 1 in an annual ephemeris. It keeps the date in the year for which the ephemeris was published, thus avoiding any reference to the previous year, even though it is the same day as December 31 of the previous year. January 0 also occurs in the epoch for the ephemeris second, "1900 January 0 at 12 hours ephemeris time". 1900 January 0 (at Greenwich Mean Noon) was also the epoch used by Newcomb's ''Tables of the Sun'', which became the epoch for the Dublin Julian day. In software In Microsoft Excel, the epoch of the 1900 date format is January 0, 1900. February 30 February 30 or 30 February is a date that does not occur on the Gregorian calendar, where the month of February contains o ...

Calendars
A calendar is a system of organizing days. This is done by giving names to periods of time, typically days, weeks, months and years. A date is the designation of a single and specific day within such a system. A calendar is also a physical record (often paper) of such a system. A calendar can also mean a list of planned events, such as a court calendar or a partly or fully chronological list of documents, such as a calendar of wills. Periods in a calendar (such as years and months) are usually, though not necessarily, synchronized with the cycle of the sun or the moon. The most common type of pre-modern calendar was the lunisolar calendar, a lunar calendar that occasionally adds one intercalary month to remain synchronized with the solar year over the long term. Etymology The term ''calendar'' is taken from , the term for the first day of the month in the Roman calendar, related to the verb 'to call out', referring to the "calling" of the new moon when it was first se ...

Julian Calendar
The Julian calendar, proposed by Roman consul Julius Caesar in 46 BC, was a reform of the Roman calendar. It took effect on , by edict. It was designed with the aid of Greek mathematicians and astronomers such as Sosigenes of Alexandria. The calendar became the predominant calendar in the Roman Empire and subsequently most of the Western world for more than 1,600 years until 1582, when Pope Gregory XIII promulgated a minor modification to reduce the average length of the year from 365.25 days to 365.2425 days and thus corrected the Julian calendar's drift against the solar year. Worldwide adoption of this revised calendar, which became known as the Gregorian calendar, took place over the subsequent centuries, first in Catholic countries and subsequently in Protestant countries of the Western Christian world. The Julian calendar is still used in parts of the Eastern Orthodox Church and in parts of Oriental Orthodoxy as well as by the Berbers. The Julian calenda ...

July
July is the seventh month of the year in the Julian and Gregorian calendars and is the fourth of seven months to have a length of 31 days. It was named by the Roman Senate in honour of Roman general Julius Caesar in 44 B.C., it being the month of his birth. Before then it was called Quintilis, being the fifth month of the calendar that started with March. It is on average the warmest month in most of the Northern Hemisphere, where it is the second month of summer, and the coldest month in much of the Southern Hemisphere, where it is the second month of winter. The second half of the year commences in July. In the Southern Hemisphere, July is the seasonal equivalent of January in the Northern hemisphere. "Dog days" are considered to begin in early July in the Northern Hemisphere, when the hot sultry weather of summer usually starts. Spring lambs born in late winter or early spring are usually sold before 1 July. July symbols *July's birthstone is the ruby, which symbolize ...

August
August is the eighth month of the year in the Julian and Gregorian calendars, and the fifth of seven months to have a length of 31 days. Its zodiac sign is Leo and was originally named ''Sextilis'' in Latin because it was the 6th month in the original ten-month Roman calendar under Romulus in 753 BC, with March being the first month of the year. About 700 BC, it became the eighth month when January and February were added to the year before March by King Numa Pompilius, who also gave it 29 days. Julius Caesar added two days when he created the Julian calendar in 46 BC (708 AUC), giving it its modern length of 31 days. In 8 BC, it was renamed in honor of Emperor Augustus. According to a Senatus consultum quoted by Macrobius, he chose this month because it was the time of several of his great triumphs, including the conquest of Egypt. Commonly repeated lore has it that August has 31 days because Augustus wanted his month to match the length of Julius Caesar's July, but t ...

Caesar Augustus
Caesar Augustus (born Gaius Octavius; 23 September 63 BC – 19 August AD 14), also known as Octavian, was the first Roman emperor; he reigned from 27 BC until his death in AD 14. He is known for being the founder of the Roman Principate, which is the first phase of the Roman Empire, and Augustus is considered one of the greatest leaders in human history. The reign of Augustus initiated an imperial cult as well as an era associated with imperial peace, the ''Pax Romana'' or '' Pax Augusta''. The Roman world was largely free from large-scale conflict for more than two centuries despite continuous wars of imperial expansion on the empire's frontiers and the year-long civil war known as the "Year of the Four Emperors" over the imperial succession. Originally named Gaius Octavius, he was born into an old and wealthy equestrian branch of the plebeian ''gens'' Octavia. His maternal great-uncle Julius Caesar was assassinated in 44 BC, and Octavius was named in Caesar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johannes De Sacrobosco
Johannes de Sacrobosco, also written Ioannes de Sacro Bosco, later called John of Holywood or John of Holybush ( 1195 – 1256), was a scholar, monk, and astronomer who taught at the University of Paris. He wrote a short introduction to the Hindu-Arabic numeral system. Judging from the number of manuscript copies that survive today, for the next 400 years it became the most widely read book on that subject. He also wrote a short textbook which was widely read and influential in Europe during the later medieval centuries as an introduction to astronomy. In his longest book, on the computation of the date of Easter, Sacrobosco correctly described the defects of the then-used Julian calendar, and recommended a solution similar to the modern Gregorian calendar three centuries before its implementation. Very little is known about the education and biography of Sacrobosco. For one thing, his year of death has been guessed at 1236, 1244, and 1256, each of which is plausible and ...

Soviet Calendar
The Soviet calendar was a modified Gregorian calendar that was used in Soviet Russia between 1918 and 1940. Several variations were used during that time. The Gregorian calendar, under the name "Western European calendar", was implemented in Soviet Russia in February 1918 by dropping the Julian dates of . As many as nine national holidays (paid days of rest) were implemented in the following decade, but four were eliminated or merged on , leaving only five national holidays: 22January, 1–2May, and 7–8November until 1951, when 22January reverted to a normal day. During the summer of 1929, five-day continuous work weeks were implemented in factories, government offices, and commercial enterprises, but not collective farms. One of the five days was randomly assigned to each worker as their day of rest, without regard to the rest days assigned to their family members or friends. These five-day work weeks continued throughout the Gregorian year, interrupted only by the five natio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Lord Of The Rings
''The Lord of the Rings'' is an epic high-fantasy novel by English author and scholar J. R. R. Tolkien. Set in Middle-earth, intended to be Earth at some time in the distant past, the story began as a sequel to Tolkien's 1937 children's book ''The Hobbit'', but eventually developed into a much larger work. Written in stages between 1937 and 1949, ''The Lord of the Rings'' is one of the best-selling books ever written, with over 150 million copies sold. The title refers to the story's main antagonist, the Dark Lord Sauron, who, in an earlier age, created the One Ring to rule the other Rings of Power given to Men, Dwarves, and Elves, in his campaign to conquer all of Middle-earth. From homely beginnings in the Shire, a hobbit land reminiscent of the English countryside, the story ranges across Middle-earth, following the quest to destroy the One Ring mainly through the eyes of the hobbits Frodo, Sam, Merry and Pippin. Although often called a trilogy, the work was intende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shire Reckoning
The Shire is a region of J. R. R. Tolkien's fictional Middle-earth, described in ''The Lord of the Rings'' and other works. The Shire is an inland area settled exclusively by hobbits, the Shire-folk, largely sheltered from the goings-on in the rest of Middle-earth. It is in the northwest of the continent, in the region of Eriador and the Kingdom of Arnor. The Shire is the scene of action at the beginning and end of Tolkien's ''The Hobbit'', and of the sequel, ''The Lord of the Rings''. Five of the protagonists in these stories have their homeland in the Shire: Bilbo Baggins (the title character of ''The Hobbit''), and four members of the Fellowship of the Ring (characters), Fellowship of the Ring: Frodo Baggins, Sam Gamgee, Merry Brandybuck and Pippin Took. The main action in ''The Lord of the Rings'' returns to the Shire near the end of the book, in "The Scouring of the Shire", when the homebound hobbits find the area under the control of Saruman's ruffians, and set things to ...

Hobbits
Hobbits are a fictional race of people in the novels of J. R. R. Tolkien. About half average human height, Tolkien presented hobbits as a variety of humanity, or close relatives thereof. Occasionally known as halflings in Tolkien's writings, they live barefooted, and dwell in homely underground houses which have windows, as they are typically built into the sides of hills. Their feet have naturally tough leathery soles (so they do not need shoes) and are covered on top with curly hair. Hobbits first appeared in the 1937 children's novel ''The Hobbit'', whose titular hobbit is the protagonist Bilbo Baggins, who is thrown into an unexpected adventure involving a dragon. In its sequel, ''The Lord of the Rings'', the hobbits Frodo Baggins, Sam Gamgee, Pippin Took, and Merry Brandybuck are primary characters who all play key roles in fighting to save their world ("Middle-earth") from evil. In ''The Hobbit'', hobbits live together in a small town called Hobbiton, which in ''The Lor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
