Duodecember
Undecimber or Undecember is a name for a thirteenth month in a calendar that normally has twelve months. Duodecimber or Duodecember is similarly a fourteenth month. Etymology The word ''undecimber'' is based on the Latin word ''undecim'' meaning "eleven". It is formed in analogy with ''December,'' which, though the twelfth month in the Gregorian calendar, derives from ''decem'' meaning "ten". The word ''undecember'' (abbreviated ''Vnde'') is recorded from a Roman inscription according to the Oxford Latin Dictionary, which defines it as "a humorous name given to the month following December". Some recent authors report the names "Undecember" and "Duodecember" for the two intercalary months inserted between November and December upon the adoption of the Julian calendar in 44 BC, including the World Calendar Association and Isaac Asimov. This claim has no contemporary evidence; Cicero refers to the months as ''intercalaris prior'' and ''intercalaris posterior'' in his letters. Histor ...

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 ...

Calendar
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 ...

Loeb Classical Library
The Loeb Classical Library (LCL; named after James Loeb; , ) is a series of books originally published by Heinemann in London, but is currently published by Harvard University Press. The library contains important works of ancient Greek and Latin literature designed to make the text accessible to the broadest possible audience by presenting the original Greek or Latin text on each left-hand page, and a fairly literal translation on the facing page. The General Editor is Jeffrey Henderson, holder of the William Goodwin Aurelio Professorship of Greek Language and Literature at Boston University. History The Loeb Classical Library was conceived and initially funded by the Jewish-German-American banker and philanthropist James Loeb (1867–1933). The first volumes were edited by Thomas Ethelbert Page, W. H. D. Rouse, and Edward Capps, and published by William Heinemann, Ltd. (London) in 1912, already in their distinctive green (for Greek text) and red (for Latin) hardcover bin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accounting Period
An accounting period, in bookkeeping, is the period with reference to which management accounts and financial statements are prepared. In management accounting the accounting period varies widely and is determined by management. Monthly accounting periods are common. In financial accounting the accounting period is determined by regulation and is usually 12 months. The beginning of the accounting period differs according to jurisdiction. For example, one entity may follow the calendar year, January to December, while another may follow April to March as the accounting period. The International Financial Reporting Standards allow a period of 52 weeks as an accounting period instead of 12 months. This method is known as the 4-4-5 calendar in British and Commonwealth usage and the 52–53-week fiscal year in the United States. In the United States the method is permitted by generally accepted accounting principles, as well as by US Internal Revenue Code Regulation 1.441-2 (IRS ...

4–4–5 Calendar
The 4–4–5 calendar is a method of managing accounting periods, and is a common calendar structure for some industries such as retail and manufacturing. It divides a year into four quarters of 13 weeks, each grouped into two 4-week "months" and one 5-week "month". The longer "month" may be set as the first (5–4–4), second (4–5–4), or third (4–4–5) unit. Its major advantage over a regular calendar is that each period is the same length and ends on the same day of the week, which is useful for planning manufacturing or work shifts. A disadvantage is that comparisons or trend analysis by "month" are flawed, as one month is 25% longer than the other two (whereas comparisons between weeks or to the same "month" in the previous year are still useful). Another disadvantage is that the 4–4–5 calendar has only 364 days (7 days x 52 weeks), meaning a 53rd week must be added every five or six years: this can make year-on-year comparison difficult. 52–53-week fiscal yea ...

Constant (programming)
In computer programming, a constant is a value that should not be altered by the program during normal execution, i.e., the value is ''constant''. When associated with an identifier, a constant is said to be "named," although the terms "constant" and "named constant" are often used interchangeably. This is contrasted with a ''variable,'' which is an identifier with a value that can be changed during normal execution, i.e., the value is ''variable.'' Constants are useful for both programmers and compilers: For programmers they are a form of self-documenting code and allow reasoning about correctness, while for compilers they allow compile-time and run-time checks that verify that constancy assumptions are not violated, and allow or simplify some compiler optimizations. There are various specific realizations of the general notion of a constant, with subtle distinctions that are often overlooked. The most significant are: compile-time (statically valued) constants, run-time (dy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adar I
Adar ( he, אֲדָר ; from Akkadian ''adaru'') is the sixth month of the civil year and the twelfth month of the religious year on the Hebrew calendar, roughly corresponding to the month of March in the Gregorian calendar. It is a month of 29 days. Names and Leap Years The month's name, like all the others from the Hebrew calendar, was adopted during the Babylonian captivity. In the Babylonian calendar the name was Araḫ Addaru or Adār ('Month of Adar'). In leap years, it is preceded by a 30-day intercalary month named Adar Aleph ( he, אדר א׳, Aleph being the first letter of the Hebrew alphabet), also known as "Adar Rishon" (''First Adar'') or "Adar I", and it is then itself called Adar Bet ( he, אדר ב׳, Bet being the second letter of the Hebrew alphabet, also known as "Adar Sheni" (''Second Adar'' or "Adar II"). Occasionally instead of Adar I and Adar II, "Adar" and "Ve'Adar" are used (Ve means 'and' thus: And-Adar). Adar I and II occur during February–March ...

Hebrew Calendar
The Hebrew calendar ( he, הַלּוּחַ הָעִבְרִי, translit=HaLuah HaIvri), also called the Jewish calendar, is a lunisolar calendar used today for Jewish religious observance, and as an official calendar of the state of Israel. It determines the dates for Jewish holidays and the appropriate Torah reading, public reading of Weekly Torah portion, Torah portions, ''yahrzeits'' (dates to commemorate the death of a relative), 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 holidays, alongside the Gregorian calendar. The present Hebrew calendar is the result of a process of development, including a Babylonian calendar, Babylonian influence. Until the Tannaitic period (approximately 10–220 Common Era, CE), the calendar employed a new lunar phase, crescent moon, with an Intercalation (timekeeping), additional month normally added every two or ...

Synodic Month
In lunar calendars, a lunar month is the time between two successive syzygies of the same type: new moons or full moons. The precise definition varies, especially for the beginning of the month. Variations In Shona, Middle Eastern, and European traditions, the month starts when the young crescent moon first becomes visible, at evening, after conjunction with the Sun one or two days before that evening (e.g., in the Islamic calendar). In ancient Egypt, the lunar month began on the day when the waning moon could no longer be seen just before sunrise. Others run from full moon to full moon. Yet others use calculation, of varying degrees of sophistication, for example, the Hebrew calendar or the ecclesiastical lunar calendar. Calendars count integer days, so months may be 29 or 30 days in length, in some regular or irregular sequence. Lunar cycles are prominent, and calculated with great precision, in the ancient Hindu Panchangam calendar, widely used in the Indian subcontin ...

Lunar Calendar
A lunar calendar is a calendar based on the monthly cycles of the Moon's phases (synodic months, lunations), in contrast to solar calendars, whose annual cycles are based only directly on the solar year. The most commonly used calendar, the Gregorian calendar, is a solar calendar system that originally evolved out of a lunar calendar system. A purely lunar calendar is also distinguished from a lunisolar calendar, whose lunar months are brought into alignment with the solar year through some process of intercalation. The details of when months begin vary from calendar to calendar, with some using new, full, or crescent moons and others employing detailed calculations. Since each lunation is approximately days, (which gives a mean synodic month as 29.53059 days or 29 days 12 hours 44 minutes and 3 seconds) it is common for the months of a lunar calendar to alternate between 29 and 30 days. Since the period of 12 such lunations, a lunar year, is 354 days, 8 h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
O'Reilly Media
O'Reilly Media (formerly O'Reilly & Associates) is an American learning company established by Tim O'Reilly that publishes books, produces tech conferences, and provides an online learning platform. Its distinctive brand features a woodcut of an animal on many of its book covers. Company Early days The company began in 1978 as a private consulting firm doing technical writing, based in the Cambridge, Massachusetts area. In 1984, it began to retain publishing rights on manuals created for Unix vendors. A few 70-page "Nutshell Handbooks" were well-received, but the focus remained on the consulting business until 1988. After a conference displaying O'Reilly's preliminary Xlib manuals attracted significant attention, the company began increasing production of manuals and books. The original cover art consisted of animal designs developed by Edie Freedman because she thought that Unix program names sounded like "weird animals".
