A week is a unit of time longer than a day and shorter than a month. In most modern calendars, including the Gregorian calendar, the week is a period of seven days, making it the longest conventionally used time unit that contains a fixed number of days. Although having no direct astronomical basis, it is widely used as a unit of time. Weeks can be thought of as forming an independent continuous calendar running in parallel with various other calendars. However, some calendars have been designed so that a given date occurs on t ...

The 20th century lasted from 1901 to 2000 in the Gregorian calendar. Common usage sometimes regards it as lasting from 1900 to 1999. The 20th century is also sometimes known as the nineteen hundreds (1900s). However, a number of arguments have been used to justify the common usage. One advanced by Stephen Jay Gould is that the first decade had only nine years, thus contradicting the definition of decade equaled 10 years. Another argument is that the astronomical year numbering system for years does have a year zero, the ...

A date in a calendar is a reference to a particular day by means of a calendar system. The calendar date allows the particular day to be identified. A person can often determine how many days a particular date comes after another date. For example, "19 February 2003", is ten days after "9 February 2003", in the Gregorian calendar. In most calendar systems, the date consists of three parts: the day of month, month, and the year. There may also be additional parts, such as the day of week. Years are usually counted from a particular starting p ...

The week as we know it was introduced by astromancers around the 3rd century, replacing the Roman calendar in use until then. The order of the days was explained by Dio Cassius (and Chaucer gave the same explanation in his Treatise on the Astrolabe). According to Cassius, it was a principle of astrology that the heavenly bodies presided, in succession, over the hours of the day. The Ptolemaic system asserts that the order of the heavenly bodies, from the farthest to the closest to the Earth, is: Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon. (This order w ...

In English, Sunday gets its name from Sunna, or Sunne the Germanic sun goddess. In ancient Jewish tradition Saturday is the sabbath. Christians in Seventh-day Adventist, 7th day Church of God, and Seventh Day Baptist churches (among others), and many Messianic Jews believe that Saturday remains the Sabbath (Hebrews 4:9). Many languages lack separate words for "Saturday" and "sabbath". Eastern Orthodox churches distinguish between the sabbath (Saturday) and what they call the Lord's Day (Sunday).

Although the Roman numerals are now written with letters of the Roman alphabet, they were originally separate symbols. The Etruscans, for example, used I Λ X ⋔ 8 ⊕ for I V X L C M. They appear to derive from notches on tally sticks, such as those used by Italian and Dalmatian shepherds into the 19th century. Thus, the I descends from a notch scored across the stick. Every fifth notch was double cut (⋀, ⋁, � ...

There are two layers of encoding that make up Unix time, and they can be usefully separated. The first layer encodes a point in time as a scalar real number, and the second encodes that number as a sequence of bits or in some other manner. Unix time - Encoding time as a number. Modern Unix time is based strictly on UTC. UTC counts time using SI seconds, and breaks up the span of time into days.

In the United Kingdom, all general elections since 1935 have been held on a Thursday, and this has become a tradition, although not a requirement of the law – which only states that an election may be held on any day "except Saturdays, Sundays, Christmas Eve, Christmas Day, Maundy Thursday, Good Friday, bank holidays in any part of the United Kingdom and any day appointed for public thanksgiving and mourning". An explanation sometimes given for the choice of Thursday as polling day is that it was, in most towns, the traditional mark ...

In the popular rhyme, "Wednesday's Child is full of woe". The film Angel Heart includes a scene where Harry Angel refers to Wednesday as "Anything Can Happen Day," in reference to the original Mickey Mouse Club television program. The term "hump day" was first used by the media on a Minneapolis, Minnesota radio station in 1965. It was thought to have been originated by an employee of Pako Corporation.

Gregorian calendar - Invention. The motivation of the Catholic Church in adjusting the calendar was to have Easter celebrated at the time that they thought had been agreed to at the First Council of Nicaea in 325. Although a canon of the council implies that all churches used the same Easter, they did not. The Church of Alexandria celebrated Easter on the Sunday after the 14th day of the Moon that falls on or after the vernal equinox, which they placed on 21 March. However, the Church of Rome still regarded 25 Ma ...

Most of the differences are in connection with concepts originating from the nineteenth century to the mid twentieth century, where new words were coined independently; almost the entire vocabularies of the car/automobile and railway/railroad industries (see Rail terminology) are different between Britain and America, for example. Other sources of difference are slang or vulgar terms, where frequent new coinage occurs, and idiomatic phrases, including phrasal verbs. The differences most likely to create confusion are those where the same word or phrase is used for two different concepts. Regional varia ...

Traditionally, the hyphen has been used in several ways: Except for noun-noun and adverb-adjective compound modifiers, when a compound modifier appears before a term, the compound modifier is generally hyphenated in order to prevent any possible misunderstanding, such as light-blue paint, twentieth-century invention, cold-hearted person, and award-winning show. Without the hyphens, there is potential confusion about whether "light" applies to "blue" or "paint", whether "twentieth" applies to "c ...
