Decimal Calendar
A decimal calendar is a calendar which includes units of time based on the decimal system. For example, a "decimal month" would consist of a year with 10 months and 36.52422 days per month. History Egyptian calendar The ancient Egyptian calendar consisted of twelve months, each divided into three weeks of ten days, with five intercalary days. Calendar of Romulus The original Roman calendar consisted of ten months; however, the calendar year only lasted 304 days, with 61 days during winter not assigned to any month. The months of Ianuarius and Februarius were added to the calendar by Numa Pompilius in 700 BCE. French Republican Calendar The French Republican Calendar was introduced (along with decimal time) in 1793, and was similar to the ancient Egyptian calendar. It consisted of twelve months, each divided into three ''décades'' of ten days, with five or six intercalary days called '' sansculottides''. The calendar was abolished by Napoleon on January 1, 180 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unit Of Time
A unit of time is any particular time interval, used as a standard way of measuring or expressing duration. The base unit of time in the International System of Units (SI), and by extension most of the Western world, is the second, defined as about 9 billion oscillations of the caesium atom. The exact modern SI definition is " he secondis defined by taking the fixed numerical value of the cesium frequency, , the unperturbed ground-state hyperfine transition frequency of the cesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1." Historically, many units of time were defined by the movements of astronomical objects. * Sun-based: the year is based on the Earth's orbital period around the sun. Historical year-based units include the Olympiad (four years), the lustrum (five years), the indiction (15 years), the decade, the century, and the millennium. * Moon-based: the month is based on the Moon's orbital period around the Earth. * Earth-based: the da ...

Decimal
The decimal numeral system (also called the base-ten positional numeral system and denary or decanary) is the standard system for denoting integer and non-integer numbers. It is the extension to non-integer numbers (''decimal fractions'') of the Hindu–Arabic numeral system. The way of denoting numbers in the decimal system is often referred to as ''decimal notation''. A decimal numeral (also often just ''decimal'' or, less correctly, ''decimal number''), refers generally to the notation of a number in the decimal numeral system. Decimals may sometimes be identified by a decimal separator (usually "." or "," as in or ). ''Decimal'' may also refer specifically to the digits after the decimal separator, such as in " is the approximation of to ''two decimals''". Zero-digits after a decimal separator serve the purpose of signifying the precision of a value. The numbers that may be represented in the decimal system are the decimal fractions. That is, fractions of the form , w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intercalary Days
Intercalation or embolism in timekeeping is the insertion of a leap day, week, or month into some calendar years to make the calendar follow the seasons or moon phases. Lunisolar calendars may require intercalations of days or months. Solar calendars The solar or tropical year does not have a whole number of days (it is about 365.24 days), but a calendar year must have a whole number of days. The most common way to reconcile the two is to vary the number of days in the calendar year. In solar calendars, this is done by adding an extra day ("leap day" or "intercalary day") to a common year of 365 days, about once every four years, creating a leap year that has 366 days ( Julian, Gregorian and Indian national calendars). The Decree of Canopus, issued by the pharaoh Ptolemy III Euergetes of Ancient Egypt in 239 BC, decreed a solar leap day system; an Egyptian leap year was not adopted until 25 BC, when the Roman Emperor Augustus instituted a reformed Alexandrian calendar.

Rutgers University
Rutgers University ( ), officially Rutgers, The State University of New Jersey, is a Public university, public land-grant research university consisting of three campuses in New Jersey. Chartered in 1766, Rutgers was originally called Queen's College and was affiliated with the Reformed Church in America, Dutch Reformed Church. It is the eighth-oldest college in the United States, the second-oldest in New Jersey (after Princeton University), and one of nine colonial colleges that were chartered before the American Revolution.Stoeckel, Althea"Presidents, professors, and politics: the colonial colleges and the American revolution", ''Conspectus of History'' (1976) 1(3):45–56. In 1825, Queen's College was renamed Rutgers College in honor of Colonel Henry Rutgers, whose substantial gift to the school had stabilized its finances during a period of uncertainty. For most of its existence, Rutgers was a Private university, private liberal arts college. It has evolved into a Mixed-sex ...

Ianuarius
, ("January"), or in full , abbreviated , was the first month of the Roman calendar, ancient Roman calendar, from which the Julian calendar, Julian and Gregorian calendar, Gregorian month of January derived. It was followed by ''Februarius'' ("February"). In the calendars of the Roman Republic, ''Ianuarius'' had 29 days. Two days were added when the Julian calendar, calendar was reformed under Julius Caesar in 45 BCE. In the oldest Roman calendar, which the Romans believed to have been instituted by their legendary founder Romulus, the first month was ''Martius (month), Martius'' ("month of Mars (mythology), Mars", March (month), March), and the calendar year had only ten months. ''Ianuarius'' and ''Februarius'' were supposed to have been added by Numa Pompilius, the second king of Rome, originally at the end of the year. It is unclear when the Romans reset the course of the year so that January and February came first. ''Ianuarius'' is conventionally thought to have taken its n ...

Februarius
''Februarius'', fully ''Mensis Februarius'' ("month of Februa"), was the shortest month of the Roman calendar from which the Julian calendar, Julian and Gregorian calendar, Gregorian month of February derived. It was eventually placed second in order, preceded by ''Ianuarius'' ("month of Janus", January) and followed by ''Martius (month), Martius'' ("month of Mars (mythology), Mars", March (month), March). In the oldest Roman calendar, which the Romans believed to have been instituted by their legendary founder Romulus, March was the first month, and the calendar year had only ten months in all. ''Ianuarius'' and ''Februarius'' were supposed to have been added by Numa Pompilius, the second king of Rome, originally at the end of the year. It is unclear when the Romans reset the course of the year so that January and February came first. ''Februarius'' was the only month in the pre-Julian calendar to have an even number of days, numbering 28. This was mathematically necessary to pe ...

Numa Pompilius
Numa Pompilius (; 753–672 BC; reigned 715–672 BC) was the Roman mythology, legendary second king of Rome, succeeding Romulus after a one-year interregnum. He was of Sabine origin, and many of Rome's most important religious and political institutions are attributed to him, such as the Roman calendar, Vestal Virgins, the cult of Mars, the cult of Jupiter, the cult of Romulus, and the office of ''pontifex maximus''. Genealogy According to Plutarch, Numa was the youngest of Pomponius's four sons, born on the day of Rome's founding (traditionally, 21 April 753 BC). He lived a severe life of discipline and banished all luxury from his home. Titus Tatius, king of the Sabines and a colleague of Romulus, gave in marriage his only daughter, Tatia (wife of Numa Pompilius), Tatia, to Numa. After 13 years of marriage, Tatia died, precipitating Numa's retirement to the countryside. According to Livy, Numa resided at Cures, Sabinum, Cures immediately before being elected king.Livy, ''Ab u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decimal Time
Decimal time is the representation of the time of day using units which are decimally related. This term is often used specifically to refer to the French Republican calendar time system used in #France, France from 1794 to 1800, during the French Revolution, which divided the day into 10 decimal hours, each decimal hour into 100 decimal minutes and each decimal minute into 100 decimal seconds (100,000 decimal seconds per day), as opposed to the more familiar standard time, which divides the day into 24 hours, each hour into 60 minutes and each minute into 60 seconds (86,400 International System of Units, SI seconds per day). The main advantage of a decimal time system is that, since the radix, base used to divide the time is the same as the one used to represent it, the representation of hours, minutes and seconds can be handled as a unified value. Therefore, it becomes simpler to interpret a timestamp and to perform conversions. For instance, 12345 is 1 decimal hour, 23 decima ...

Sansculottides
The Sansculottides (; also Epagomènes; ) are holidays following the last month of the year on the French Republican calendar which was used following the French Revolution from approximately 1793 to 1805. The Sansculottides, named after the sans-culottes, append the twelve, 30-day months of the Republican Calendar with five complementary days in a common year or six complementary days in a leap year, so that the calendar year would approximately match the tropical year. They follow the last day of Fructidor, the last month of the year, and precede the first day of Vendémiaire. Each of the Sansculottides were assigned as one of the ten days of the week. Even though the five or six days were less than a full week, the following 1 Vendémiaire would still be a ''primidi'', skipping four or five days of the week. The Sansculottides belong to the summer quarter. They begin on 17 or 18 September and approximately the end on the autumn equinox, on 22 or 23 September on the Gr ...

Napoleon
Napoleon Bonaparte (born Napoleone di Buonaparte; 15 August 1769 – 5 May 1821), later known by his regnal name Napoleon I, was a French general and statesman who rose to prominence during the French Revolution and led Military career of Napoleon, a series of military campaigns across Europe during the French Revolutionary and Napoleonic Wars from 1796 to 1815. He led the French First Republic, French Republic as French Consulate, First Consul from 1799 to 1804, then ruled the First French Empire, French Empire as Emperor of the French from 1804 to 1814, and briefly again in 1815.

Gregorian Calendar
The Gregorian calendar is the calendar used in most parts of the world. It went into effect in October 1582 following the papal bull issued by Pope Gregory XIII, which introduced it as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years slightly differently to make the average calendar year 365.2425 days long rather than the Julian calendar's 365.25 days, thus more closely approximating the 365.2422-day tropical year, "tropical" or "solar" year that is determined by the Earth's revolution around the Sun. The rule for leap years is that every year divisible by four is a leap year, except for years that are divisible by 100, except in turn for years also divisible by 400. For example 1800 and 1900 were not leap years, but 2000 was. There were two reasons to establish the Gregorian calendar. First, the Julian calendar was based on the estimate that the average solar year is exactly 365.25 days long, an overestimate of a li ...
