Leap year

A leap year (or intercalary year) is a year containing an extra day or month in order to keep the calendar year in sync with an astronomical or seasonal year. Seasons and astronomical events do not repeat at an exact number of days, so a calendar which had the same number of days in each year would over time drift with respect to the event it was supposed to track. By occasionally inserting (or intercalating) an additional day or month into the year, the drift can be corrected. Leap years (which keep the calendar in sync with the year) should not be confused with leap seconds (which keep clock time in sync with the day).

Gregorian calendar

The Gregorian calendar, the current standard calendar in most of the world, adds a 29th day to February in all years evenly divisible by 4, except for century years (those ending in -00), which receive the extra day only if they are evenly divisible by 400. Thus 1996 was a leap year whereas 1999 was not, and 1600, 2000 and 2400 are leap years but 1700, 1800, 1900 and 2100 are not. The reasoning behind this rule is as follows:
- The Gregorian calendar is designed to keep the vernal equinox on or close to March 21, so that the date of Easter (celebrated on the Sunday after the 14th day of the Moon that falls on or after 21 March) remains correct with respect to the vernal equinox.
- The vernal equinox year is currently about 365.242375 days long.
- The Gregorian leap year rule gives an average year length of 365.2425 days. This difference of a little over 0.0001 days means that in around 8,000 years, the calendar will be about one day behind where it should be. But in 8,000 years' time the length of the vernal equinox year will have changed by an amount we can't accurately predict (see below). So the Gregorian leap year rule does a good enough job. Image:Gregoriancalendarleap.png

Which day is the leap day?

The Gregorian calendar is a modification of the Julian calendar first used by the Romans. The Roman calendar originated as a lunar calendar (though from the 5th century BC it no longer followed the real moon) and named its days after three of the phases of the moon: the new moon (calends, hence "calendar"), the first quarter (nones) and the full moon (ides). Days were counted down (inclusively) to the next named day, so 24 February was ante diem sextum calendas martii ("the sixth day before the calends of March"). Since 45 BC, February in a leap year had two days called "the sixth day before the calends of March". The extra day was originally the second of these, but since the third century it was the first. Hence the term bissextile day for 24 February in a bissextile year. Where this custom is followed, anniversaries after the inserted day are moved in leap years. For example, the former feast day of Saint Matthias, 24 February in ordinary years, would be 25 February in leap years. This historical nicety is, however, in the process of being discarded: The European Union declared that, starting in 2000, 29 February rather than 24 February would be leap day, and the Roman Catholic Church also now uses 29 February as leap day. The only tangible difference is felt in countries that celebrate feast days.

Julian calendar

The Julian calendar adds an extra day to February in years divisible by 4. This rule gives an average year length of 365.25 days. The excess of about 0.0076 days with respect to the vernal equinox year means that the vernal equinox moves a day earlier in the calendar every 130 years or so.

Revised Julian Calendar

The Revised Julian calendar adds an extra day to February in years divisible by 4, except for years divisible by 100 that do not leave a remainder of 200 or 600 when divided by 900. This rule agrees with the rule for the Gregorian calendar until 2799. The first year that dates in the Revised Julian calendar will not agree with the those in the Gregorian calendar will be 2800, because it will be a leap year in the Gregorian calendar but not in the Revised Julian calendar. This rule gives an average year length of 365.242222… days. This is a very good approximation to the mean tropical year, but because the vernal equinox tropical year is slightly longer, the Revised Julian calendar does not do as good a job as the Gregorian calendar of keeping the vernal equinox on or close to 21 March.

Chinese calendar

The Chinese calendar is lunisolar, so a leap year has an extra month, often called an embolismic month after the Greek word for it. In the Chinese calendar the leap month is added according to a complicated rule, which ensures that month 11 is always the month that contains the northern winter solstice. The intercalary month takes the same number as the preceding month; for example, if it follows the second month then it is simply called "leap second month".

Hebrew calendar

The Hebrew calendar is also lunisolar with an embolistic month. In the Hebrew calendar the extra month is called Adar Alef (first Adar) and is added before Adar, which then becomes Adar Sheni (second Adar). According to the Metonic cycle, this is done seven times every nineteen years, specifically, in years, 3, 6, 8, 11, 14, 17, and 19. In addition, the Hebrew calendar has postponement rules that postpone the start of the year by one or two days. The year before the postponement gets one or two extra days, and the year whose start is postponed loses one or two days. These postponement rules reduce the number of different combinations of year length and starting day of the week from 28 to 14, and regulate the location of certain religious holidays in relation to the Sabbath.

Hindu Calendar

In the Hindu calendar, which is a lunisolar calendar, the embolismic month is called adhika maas (extra month). It is the month in which the sun is in the same sign of the stellar zodiac on two consecutive dark moons.

Iranian calendar

The Iranian calendar also has a single intercalated day once in every four years, but every 33 years or so the leap years will be five years apart instead of four years apart. The system used is more accurate and more complicated, and is based on the time of the March equinox as observed from Teheran. The 33-year period is not completely regular; every so often the 33-year cycle will be broken by a cycle of 29 or 37 years.

Long term leap year rules

The accumulated difference between the Gregorian calendar and the vernal equinoctial year amounts to 1 day in about 8,000 years. This suggests that the calendar needs to be improved by another refinement to the leap year rule: perhaps by avoiding leap years in years divisible by 8,000. (The most common such proposal is to avoid leap years in years divisible by 4,000 [http://www.google.com/search?q=%22gregorian+calendar%22+error+%22leap+year%22+4000]. This is based on the difference between the Gregorian calendar and the mean tropical year. Others claim, erroneously, that the Gregorian calendar itself already contains a refinement of this kind [http://www.straightdope.com/mailbag/mleapyr.html].) However, there is little point in planning a calendar so far ahead because over a timescale of tens of thousands of years the number of days in a year will change for a number of reasons, most notably: #Precession of the equinoxes moves the position of the vernal equinox with respect to perihelion and so changes the length of the vernal equinoctial year. #Tidal acceleration from the sun and moon slows the rotation of the earth, making the day longer. In particular, the second component of change depends on such things as post-glacial rebound and sea level rise due to climate change. We can't predict these changes accurately enough to be able to make a calendar that will be accurate to a day in tens of thousands of years.

Marriage proposal

There is a tradition, said to go back to Saint Patrick and Saint Bridget in 5th century Ireland, whereby women may only make marriage proposals in leap years.

Saint Patrick and the leap year

:Saint Patrick, having driven the frogs out of the bogs was walking along the shores of Lough Neagh, when he was accosted by Saint Bridget in tears, and was told that a mutiny had broken out in the nunnery over which she presided, the ladies claiming the right of popping the question. :Saint Patrick said he would concede them the right every seventh year, when Saint Bridget threw her arms round his neck, and exclaimed, "Arrah, Pathrick, jewel, I daurn't go back to the girls wid such a proposal. Make it one year in four." Saint Patrick replied, "Bridget, acushla, squeeze me that way again, an' I'll give ye leap-year, the longest of the lot." Saint Bridget, upon this, popped the question to St Patrick himself, who, of course, could not marry: so he patched up the difficulty as best he could with a kiss and a silk gown. (Source: Evans, Ivor H, Brewer's Dictionary of Phrase and Fable, Cassell, London, 1988) According to a 1288 law in Scotland, fines were levied if the proposal was refused by the man; compensation ranged from a kiss to a silk gown to soften the blow. Because men felt that put them at too great a risk, the tradition was in some places tightened to restricting female proposals to 29 February.

Birthdays

A person who was born on 29 February may be called a "leapling". In non-leap years they usually celebrate their birthday on 28 February or 1 March. There are many instances in children's literature where a person's claim to be only a quarter of their actual age turns out be based on counting their leap-year birthdays. A similar device is used in the plot of the Gilbert and Sullivan operetta The Pirates of Penzance.

Denmark

The Kingdom of Denmark (Danish: Kongeriget Danmark) is geographically the smallest and southernmost Nordic country, and is part of the European Union. It is located at in Scandinavia which is in northern Europe, but it does not lie on the Scandinavian Peninsula. Denmark borders the Baltic Sea and the North Sea, and consists of a peninsula attached to Northern Germany named Jutland (Jylland), the islands Funen (Fyn), Zealand (Sjælland), Bornholm and many smaller islands, the waters of which are often referred to as the Danish Archipelago. Denmark lies north of Germany (its only land neighbour), southwest of Sweden, and south of Norway. Greenland and the Faroe Islands are Crown territories of Denmark, each with political home rule.

History

:Main article: History of Denmark The origin of Denmark is lost in prehistory. The oldest Danevirke is from the 7th century, at the same time as the new Runic alphabet. Oldest city: Ribe is from about 810. Up into the 10th century the Danes were known as Vikings, together with Norwegians and Swedes, colonising, raiding and trading in all parts of Europe. Viking explorers first discovered Iceland by accident in the ninth century, en route to the Faroe Islands. Erik the Red, or Erik Thorvaldson, was exiled from the colony for manslaughter in 980, and set sail for the west, to explore the lands to the west. He established the first settelments in Greenland around this time, naming the land, according to ledgend, to attract settelers. Erik's son Leif the Lucky(Leif Ericson)finally set foot in the Americas around the year 1000. While some say he was blown off course, it is most likely that he was diliberatly seeking the land spotted by Bjarni Herjulfsson several years earlier. He established a colony at L'Anse aux Meadows, which lasted only a year. Two further attempts at colonization by his brother ended in failure. At various times the King of Denmark has ruled parts of England and Ireland, Norway, Sweden, Finland, Iceland, France, especially Normandy and the Virgin Islands, Tranquebar in India, Estonia and what is now Northern Germany. Scania, Blekinge and Halland were part of Denmark for most of its early history, but were lost to Sweden in 1658. The union with Norway was dissolved in 1814, when Norway entered a new union with Sweden (until 1905). The Danish liberal and national movement gained momentum in the 1830s, and after the European revolutions of 1848 Denmark became a constitutional monarchy June 5 1849. After the Second War of Schleswig (Danish: Slesvig) in 1864 Denmark was forced to cede Schleswig-Holstein to Prussia, in a defeat that left deep marks in the Danish national identity. After this point Denmark adopted a policy of neutrality, as a result of which Denmark stayed neutral in World War I. Following the defeat of Germany, Denmark was offered by the Versailles powers the return of Schleswig-Holstein. Fearing German irredentism Denmark refused to consider the return of Holstein and insisted on a plebiscite concerning the return of Schleswig. In 1920, following the plebiscite, Northern Schleswig was recovered by Denmark. Despite its continued neutrality Denmark was invaded by Germany (Operation Weserübung), on April 9, 1940. Though at first accorded self-rule (which ended in 1943 due to a mounting resistance movement), Denmark remained militarily occupied throughout World War II. The Danish sympathy for the Allied Cause was strong; 1,900 Danish Police Officers were arrested by the Gestapo and sent, under guard, to be interned in Buchenwald. After the war, Denmark became one of the founding members of NATO and, in 1973, joined the European Economic Community (later, the European Union).

Politics and government

:Main article: Politics of Denmark Denmark is the oldest monarchy in the world. In 1849, it became a constitutional monarchy with the adoption of a new constitution. The monarch is formally head of state, a role which is mainly ceremonial, since executive power is exercised by the cabinet ministers, with the prime minister acting as the first among equals (primus inter pares). Legislative power is vested in both the government and the Danish parliament, known as the Folketing, which consists of (no more than) 179 members. The Danish Judiciary is functionally and administratively independent of the executive and the legislature. Elections for parliament must be held at least every four years; but the prime minister can call for an earlier election, if he so decides. Should parliament succeed in a vote of no confidence against the Prime Minister the entire government resigns. The country is often run by minority governments.

Counties

:Main article: Counties of Denmark Denmark is divided into 13 counties (amter, singular: amt), and 271 municipalities (kommuner, singular kommune). The coming Danish Municipal Reform will replace the counties with five new regions and reduce the number of municipalities to 98. The new municipalities will take over most of the responsibilities of the former counties. Most of the new municipalities will have a population of at least 20,000 people. The reform will be implemented on 1 January 2007.
- Aarhus (Århus)
- Frederiksborg
- Funen (Fyn)
- Copenhagen (København)
- North Jutland (Nordjylland)
- Ribe
- Ringkjøbing
- Roskilde
- South Jutland (Sønderjylland)
- Storstrøm
- Vejle
- Viborg
- West Zealand (Vestsjælland) Three municipalities have county privileges:
- Bornholm (regional municipality)
- Copenhagen (København)
- Frederiksberg Copenhagen County comprises the municipalities of metropolitan Copenhagen, except Copenhagen Municipality and Frederiksberg Municipality. Bornholm Regional Municipality comprise the five former municipalities on the island Bornholm and the island's former county. Greenland and the Faroe Islands also belong to the Kingdom of Denmark, but have autonomous status and are largely self-governing, and are each represented by two seats in the parliament.

Geography

Faroe Islands Faroe Islands :Main article: Geography of Denmark Denmark consists of the peninsula of Jutland (Jylland) and 405 named islands. Of these, 323 are habited, with the largest being Zealand (Sjælland) and Funen (Fyn). The island of Bornholm is located somewhat east of the rest of the country, in the Baltic Sea. Many of the larger islands are connected by bridges; the Øresund Bridge connects Zealand with Sweden, the Great Belt Bridge connects Funen with Zealand, and the Small Belt Bridge connects Jutland with Funen. Ferries connect one to the smaller islands. The country is mostly flat with little elevation; the highest natural point is Møllehøj, at 170.86 metres. The climate is temperate, with mild winters and cool summers. Main cities are the capital Copenhagen (on Zealand), Aarhus, Aalborg (on Jutland) and Odense (on Fyn)..

Economy

:Main article: Economy of Denmark This thoroughly modern market economy features high-tech agriculture, up-to-date small-scale and corporate industry, extensive government welfare measures, comfortable living standards, a stable currency, and high dependence on foreign trade. Denmark is a net exporter of food and energy and has a comfortable balance of payments surplus. The Danish economy is highly unionized; 75% of its labour force [http://www.iht.com/articles/2005/01/10/business/unions2.html] are members of a union in the Danish Confederation of Trade Unions. Relationships between unions and employers are cooperative: unions have a day-to-day role in managing the workplace, and their representatives sit on most companies' board of directors. Rules on work schedules and pay are negotiated between unions and employers, with minimal government involvement. The government has been very successful in meeting, and even exceeding, the economic convergence criteria for participating in the third phase (a common European currency) of the Economic and Monetary Union (EMU), but Denmark, in a September 2000 referendum, reconfirmed its decision not to join the 12 other EU members in the euro. Even so, the Danish currency remains pegged to the euro. Denmark has also placed first on the Economist Intelligence Unit's "e-readiness" rankings for the past two years. "A country's "e-readiness" is a measure of its e-business environment, a collection of factors that indicate how amenable a market is to Internet-based opportunities."

Demographics

:Main article: Demographics of Denmark The majority of the population is of Scandinavian descent, with small groups of Inuit (from Greenland), Faroese, and immigrants. According to official statistics in 2003 immigrants made up 6.2% of the total population. Danish is spoken in the entire country, although a small group near the German border also speaks German. Many Danes are fluent in English as well, particularly those in larger cities and the youth, who are taught English in school. Of the religions in Denmark, according to official statistics from January 2002 84.3% of Danes are members of the Lutheran state church, the Danish People's Church (Den Danske Folkekirke), also known as the Church of Denmark. The rest are primarily of other Christian denominations and also about 2% are Muslims. For the last decade Danish People's Church has seen a decline in the number of memberships. In the later years, the old norse religion Asatru has begun to reemerge. Asatru was approved as a religious movement by the Danish government on November 8th 2003.

Culture

:Main article: Culture of Denmark Perhaps the most famous Dane is actually a mythical figure: Hamlet, the title character of William Shakespeare's greatest play, which was set in a real castle (Kronborg) in Helsingør, north of Copenhagen. The Dane most well-known in foreign countries is probably Hans Christian Andersen, a writer mostly famous for such fairy tales as The Emperor's New Clothes, The Little Mermaid, and The Ugly Duckling.

Christopher Columbus

__NOEDITSECTION__ :For information about the film director, see the article on Chris Columbus. Christopher Columbus (145120 May 1506) (Cristóbal Colón in Spanish, Cristoforo Colombo in Italian, Cristóvão Colombo in Portuguese, Χριστόφορος Κολόμβος in Greek, Cristòfor Colom in Catalan) was an explorer and trader who crossed the Atlantic Ocean and reached the Americas on October 12, 1492 under the flag of Castile. History places a great significance on his landing in America in 1492, with the entire period of the history of the Americas before this date usually known as Pre-Columbian, and the anniversary of this event, Columbus Day, celebrated in many countries in the Americas. Although there is evidence of Pre-Columbian trans-oceanic contact, and it is questionable whether one person can "discover" a place which is inhabited by other people, Columbus is often credited as having discovered America. His voyage marked the beginning of the Spanish and European colonization of the Americas. He was most likely Genoese, although some historians claim he could have been born in other places, from the Crown of Aragón to the Kingdoms of Galicia or Portugal, or in the Greek island of Chios among others.

Background

Chios Columbus believed that the Earth was a relatively small sphere, and argued that a ship could reach India via a westward course. The widespread notion that Columbus encountered opposition based on the idea that the Earth was flat is a literary myth created by Washington Irving. Educated people in Columbus's time agreed that the earth was round; anyone familiar with seafaring certainly knew it, since the roundness of the Earth forms the basis of celestial navigation. The main debate was over whether a ship could circumnavigate the planet without running out of food or getting stuck in windless regions such as the Sargasso Sea. Columbus was not the first European to reach the continent. Most historians today acknowledge the fact that Leif Ericson had traveled to North America from Iceland in the 11th century and set up a short-lived colony at L'Anse aux Meadows. There are also many theories of expeditions to the Americas by a variety of peoples throughout time; see Pre-Columbian trans-oceanic contact, one of the most consistent is the exploration (before 1472) of two, led by João Vaz Corte-Real to Terra Verde (today's Newfoundland). Giovanni Caboto (better known as John Cabot) was first to reach the American mainland (which Columbus did not reach until his third voyage). However, there is one thing that sets off Columbus' first voyage from all of these: less than two decades later, the existence of America was known to the general public throughout Europe. This is likely due to the invention of the printing press. Additionally, although Columbus is credited in Western classical education as the "discoverer of America" , the two continents are named after Amerigo Vespucci, who reached what is now the coast of Brazil in 1501 and whose name was first applied to the map by cartographer Martin Waldseemüller. Columbus landed in the Bahamas and later explored much of the Caribbean, including the isles of Juana (Cuba) and La Española (Hispaniola), as well as the coasts of Central and South America. He never reached the present-day United States where "Columbus Day" (The second monday of October, with 12 October being the anniversary of Columbus' landing in the Bahamas) is celebrated as a holiday. Unlike the voyage of the Icelanders, Columbus' voyages led to a relatively quick, general and lasting recognition of the existence of the New World by the Old World, the Columbian Exchange of species (both those harmful to humans, such as viruses, bacteria, and parasites, and beneficial to humans, such as tomatoes, potatoes, maize, and horses), and the first large-scale colonization of the Americas by Europeans. Columbus remains a controversial figure. Some – including many Native Americans – view him as responsible, directly or indirectly, for the deaths of tens, if not hundreds, of millions of indigenous peoples, exploitation of the Americas by Europe, and slavery in the West Indies. Others honor him for the massive boost his explorations gave to Western expansion and culture. Italian Americans hail Columbus as an icon of their heritage. It has generally been accepted that he was Genovese, although doubts have persistently been voiced regarding this. His name in Italian is Cristoforo Colombo, in Spanish is Cristóbal Colón, in Catalan it is Cristòfor Colom and in Portuguese Cristóvão Colombo. Columbus is a Latinized form of his surname. The Latin roots of his name can be translated "Christ-bearer, Dove". Columbus' signature reads Xpo ferens ("Bearing Christ"). Columbus claimed governorship of the new territories (by prior agreement with the Spanish monarchs) and made several more journeys across the Atlantic. While regarded by some as an excellent navigator, he was seen by many contemporaries as a poor administrator and was stripped of his governorship in 1500.

Early life

There are various versions of Columbus's origins and life before 1476. (See Columbus's National Origin.) The account that has traditionally been supported by most historians is as follows: Columbus was born between August 26 and October 31 in the year 1451, in the Italian port city of Genoa. His father was Domenico Colombo, a woollens merchant, and his mother was Susanna Fontanarossa, the daughter of a woollens merchant. Christopher had three younger brothers, Bartolomeo, Giovanni Pellegrino, and Giacomo, and a sister, Bianchinetta. Bartolomeo In 1470, the family moved to Savona, where Christopher worked for his father in wool processing. During this period he studied cartography with his brother Bartolomeo. Christopher received almost no formal education; a voracious reader, he was largely self-taught. In 1474, Columbus joined a ship of the Spinola Financiers, who were Genoese patrons of his father. He spent a year on a ship bound towards Chios (an island in the Aegean Sea) and, after a brief visit home, spent a year in Chios. It is believed that this is where he recruited some of his sailors. A 1476, commercial expedition gave Columbus his first opportunity to sail into the Atlantic Ocean. The fleet came under attack by French privateers off the Cape of St. Vincent, Portugal. Columbus's ship was burned and he swam six miles to shore. By 1477, Columbus was living in Lisbon. Portugal had become a center for maritime activity with ships sailing for England, Ireland, Iceland, Madeira, the Azores, and Africa. Columbus's brother Bartolomeo worked as a mapmaker in Lisbon. At times, the brothers worked together as draftsmen and book collectors. He became a merchant sailor with the Portuguese fleet, and sailed to Iceland via Ireland in 1477. He sailed to Madeira in 1478 to purchase sugar, and along the coasts of West Africa between 1482 and 1485, reaching the Portuguese post of Elmina Castle in the Gulf of Guinea coast. Columbus married Felipa Perestrello Moniz, a daughter from a noble Portuguese family with some Italian ancestry, in 1479. Felipa's father, Bartolomeu Perestrelo, had partaken in finding the Madeira Islands and owned one of them (Porto Santo Island), but died when Felipa was a baby, leaving his second wife a wealthy widow. As part of his dowry, the mariner received all of Perestello's charts of the winds and currents of the Portuguese possessions of the Atlantic. Columbus and Felipa had a son, Diego Colón in 1480. Felipa died in January of 1485. Columbus later found a lifelong partner in Spain, an orphan named Beatriz Enriquez. She was living with a cousin in the weaving industry of Córdoba. They never married, but Columbus left Beatriz a rich woman and directed Diego to treat her as his own mother. The two had a son, Ferdinand in 1488. Both boys served as pages to Prince Juan, son of Ferdinand and Isabella of Castile, and each later contributed, with fabulous success, to the rehabilitation of their father's reputation.

Columbus' idea

Christian Europe, which had long enjoyed safe passage to India and China — sources of valued goods such as silk and spices — under the hegemony of the Mongol Empire (the Pax Mongolica, or "Mongol peace"), was now, after the fragmentation of the Mongol Empire, under complete economic blockade by Muslim states. In response to Muslim domination on land, Portugal sought an eastward sea route to the Indies, and promoted the establishment of trading posts and later colonies along the African coast. Columbus had a different idea. By the 1480s, he had developed a plan to travel to the Indies (then construed roughly as all of south and east Asia) by instead sailing west across the "Ocean Sea" (the Atlantic Ocean). It is sometimes claimed that the reason Columbus had difficulty obtaining support for his plan was that Europeans believed that the Earth
