Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Republic of Ireland
–
Ireland, also known as the Republic of Ireland, is a sovereign state in north-western Europe occupying about five-sixths of the island of Ireland. The capital and largest city is Dublin, which is located on the part of the island. The state shares its land border with Northern Ireland, a part of the United Kingdom. It is otherwise surrounded by the Atlantic Ocean, with the Celtic Sea to the south, Saint Georges Channel to the south-east, and it is a unitary, parliamentary republic. The head of government is the Taoiseach, who is elected by the Dáil and appointed by the President, the state was created as the Irish Free State in 1922 as a result of the Anglo-Irish Treaty. It was officially declared a republic in 1949, following the Republic of Ireland Act 1948, Ireland became a member of the United Nations in December 1955. It joined the European Economic Community, the predecessor of the European Union, after joining the EEC, Ireland enacted a series of liberal economic policies that resulted in rapid economic growth. The country achieved considerable prosperity between the years of 1995 and 2007, which known as the Celtic Tiger period. This was halted by a financial crisis that began in 2008. However, as the Irish economy was the fastest growing in the EU in 2015, Ireland is again quickly ascending league tables comparing wealth and prosperity internationally. For example, in 2015, Ireland was ranked as the joint sixth most developed country in the world by the United Nations Human Development Index and it also performs well in several national performance metrics, including freedom of the press, economic freedom and civil liberties. Ireland is a member of the European Union and is a member of the Council of Europe. The 1922 state, comprising 26 of the 32 counties of Ireland, was styled, the Constitution of Ireland, adopted in 1937, provides that the name of the State is Éire, or, in the English language, Ireland. Section 2 of the Republic of Ireland Act 1948 states, It is hereby declared that the description of the State shall be the Republic of Ireland. The 1948 Act does not name the state as Republic of Ireland, because to have done so would have put it in conflict with the Constitution. The government of the United Kingdom used the name Eire, and, from 1949, Republic of Ireland, for the state, as well as Ireland, Éire or the Republic of Ireland, the state is also referred to as the Republic, Southern Ireland or the South. In an Irish republican context it is referred to as the Free State or the 26 Counties. From the Act of Union on 1 January 1801, until 6 December 1922, during the Great Famine, from 1845 to 1849, the islands population of over 8 million fell by 30%

Provinces of Ireland
–
Ireland has historically been divided into four provinces, Connacht, Leinster, Munster and Ulster. The provinces of Ireland serve no administrative or political purposes, a king of over-kings, a rí ruirech was often a provincial or semi-provincial king to whom several ruiri were subordinate. Entities belonging to the 1st and 2nd millennia are listed and these do not all belong to the same periods. Over the centuries, the number of provincial kings varied between three and six, no more than six genuine rí ruirech were ever contemporary, with the average being three or four. Also, following the Norman invasion, the situation became more condensed and complicated than previously. The Norman invasion began in 1169, and the Normans went on to occupy Ireland until 1541, in the early Irish annals these five ancient political divisions were referred to as cúigí such as the fifth of Munster, the fifth of Ulster and so on. Later record-makers dubbed them provinces, in imitation of the Roman imperial provinciae, in modern times they have become associated with groups of counties, although they have no legal status. The provinces were supplanted by the present system of counties after the Norman invasion, during the Tudor conquest, and for about a century after, provincial Presidencies existed in Connacht and Munster, serving a primarily military role. Six of the nine Ulster counties form modern-day Northern Ireland, which is part of the United Kingdom of Great Britain, Northern Ireland is sometimes called a province of the United Kingdom. These two inconsistent usages of the province can cause confusion. This dinnseanchas poem named Ard Ruide poetically describes the kingdoms of Ireland, Munster in the south is the kingdom of music and the arts, of harpers, of skilled ficheall players and of skilled horsemen. The fairs of Munster were the greatest in all Ireland, the last kingdom, Meath, is the kingdom of Kingship, of stewardship, of bounty in government, in Meath lies the Hill of Tara, the traditional seat of the High King of Ireland. The ancient earthwork of Tara is called Rath na Ríthe

Ulster
–
Ulster is a province in the north of the island of Ireland. In ancient Ireland, it was one of the fifths ruled by a rí ruirech, the definition of the province was fluid from early to medieval times. It took a shape in the reign of King James I of England when all the counties of Ireland were eventually shired. This process of evolving conquest had been under way since the Norman invasion of Ireland, particularly as advanced by the Cambro-Norman magnates Hugh de Lacy, Ulster was a central topic role in the parliamentary debates that eventually resulted in the Government of Ireland Act 1920. Under the terms of the Act, Ireland was divided into two territories, Southern Ireland and Northern Ireland, with the passing through the province. While these six counties and two boroughs were all in the province of Ulster, three other counties of the province – Cavan, Donegal and Monaghan – were assigned to the Irish Free State. Ulster has no function for local government purposes in either country. However, for the purposes of ISO-3166-2, Ulster is used to refer to the three counties of Cavan, Donegal and Monaghan only, which are given country sub-division code IE-U. It has also suggested to have derived from Uladh plus the Norse suffix ster. The Irish name, Cúige Uladh, means the province of the Ulaid, the Ulaidh were a group of tribes who dwelt in the region. Ulaidh has historically been anglicised as Ulagh or Ullagh and Latinised as Ulidia or Ultonia, the latter two have yielded the terms Ulidian and Ultonian. Words that have used in English are Ullish and Ulsterman/Ulsterwoman. Northern Ireland is often referred to as Ulster, despite including only six of Ulsters nine counties and this usage is most common amongst people in Northern Ireland who are unionist, although it is also used by the media throughout the United Kingdom. Most Irish nationalists object to the use of Ulster in this context, Ulster has a population of just over 2 million people and an area of 21,552 square kilometres. About 62% of the area of Ulster is in the UK while the remaining 38% is in the Republic of Ireland. Ulsters biggest city, Belfast, has an population of over half a million inhabitants, making it the second-largest city on the island of Ireland. Three Ulster counties – Cavan, Donegal and Monaghan – form part of the Republic of Ireland, about half of Ulsters population lives in counties Antrim and Down. 8% to 42. 7%. While the traditional counties continue to demarcate areas of government in the Republic of Ireland

Counties of Ireland
–
The counties of Ireland are sub-national divisions that have been, and in some cases continue to be, used to geographically demarcate areas of local government. These land divisions were formed following the Norman invasion of Ireland in imitation of the then in use as units of local government in the Kingdom of England. The older term shire was historically equivalent to county, the principal function of the county was to impose royal control in the areas of taxation, security and the administration of justice at the local level. Cambro-Norman control was limited to the southeastern parts of Ireland. The powers exercised by the Cambro-Norman barons and the Old English nobility waned over time, new offices of political control came to be established at a county level. In the Republic of Ireland, some counties have been resulting in the creation of new counties. Along with certain defined cities, counties form the basis for the demarcation of areas of local government in the Republic of Ireland. Currently, there are 26 county level,3 city level and 2 city and county entities – the modern equivalent of counties corporate – that are used to demarcate areas of government in the Republic. In Northern Ireland, counties are no longer used for local government, upon the partition of Ireland in 1921, the county became one of the basic land divisions employed, along with county boroughs. The word county has come to be used in different senses for different purposes, in common usage, many people have in mind the 32 counties that existed prior to 1838 – the so-called traditional counties. However, in usage in the Republic of Ireland, the term often refers to the 28 modern counties. The term is also conflated with the 31 areas currently used to demarcate areas of government in the Republic of Ireland at the level of LAU1. In Ireland, usage of the county nearly always comes before rather than after the county name, thus County Roscommon in Ireland as opposed to Roscommon County in Michigan. The former Kings County and Queens County were exceptions, these are now County Offaly and County Laois, the abbreviation Co. is used, as in Co. There appears to be no official guidance in the matter, as even the local council uses all three forms, the synonym shire is not used for Irish counties, although the Marquessate of Downshire was named in 1789 after County Down. Parts of some towns and cities were exempt from the jurisdiction of the counties that surrounded them and these towns and cities had the status of a County corporate, many granted by Royal Charter, which had all the judicial, administrative and revenue raising powers of the regular counties. The political geography of Ireland can be traced with accuracy from the 6th century. At that time Ireland was divided into a patchwork of petty kingdoms with a political hierarchy which

County Donegal
–
County Donegal is a county of Ireland. It is part of the Border Region of the Republic of Ireland and is in the province of Ulster and it is named after the town of Donegal in the south of the county. Donegal County Council is the council for the county and Lifford serves as the county town. The population of the county is 158,755 according to the 2016 census and it has also been known as Tyrconnell, after the historic territory of the same name. In terms of size and area, it is the largest county in Ulster, uniquely, County Donegal shares a small border with only one other county in the Republic of Ireland – County Leitrim. The greater part of its border is shared with three counties of Northern Ireland, County Londonderry, County Tyrone and County Fermanagh. While Lifford is the county town, Letterkenny is by far the largest town in the county with a population of 19,588, Letterkenny and the nearby city of Derry form the main economic axis of the northwest of Ireland. Indeed, what became the City of Derry was officially part of County Donegal up until 1610, there are two Gaeltacht districts in the west, The Rosses, centred on the town of Dungloe, and Gweedore. Another Gaeltacht district is located in the north-west, Cloughaneely, centred on the town of Falcarragh, the most northerly part of the island of Ireland is the location for three peninsulas of outstanding natural beauty, Inishowen, Fanad and Rosguill. The main population centre of Inishowen, Irelands largest peninsula, is Buncrana, in the east of the county lies the Finn Valley. The Laggan district is centred on the town of Raphoe, according to the 1841 Census, County Donegal had a population of 296,000 people. As a result of famine and emigration, the population had reduced by 41,000 by 1851, by the time of the 1951 Census the population was only 44% of what it had been in 1841. The 2006 Census, undertaken by the States Central Statistics Office, had County Donegals population standing at 147,264, according to the 2011 Census, the countys population had grown to 161,137. It has an indented coastline forming natural sea loughs, of which both Lough Swilly and Lough Foyle are the most notable. The Slieve League cliffs are the sixth-highest sea cliffs in Europe, the climate is temperate and dominated by the Gulf Stream, with warm, damp summers and mild wet winters. Two permanently inhabited islands, Arranmore and Tory Island, lie off the coast, Irelands second longest river, the Erne, enters Donegal Bay near the town of Ballyshannon. The River Erne, along with other Donegal waterways, has been dammed to produce hydroelectric power, the River Foyle separates part of County Donegal from parts of both counties Londonderry and Tyrone. A survey of the marine algae of County Donegal was published in 2003

West European Time
–
Western European Time is a time zone covering parts of western and northwestern Europe. WEST is called British Summer Time in the UK and is known as Irish Standard Time in Ireland. Conversely, Iceland and eastern Greenland are included although both are west of 7. 5°W, in September 2013, a Spanish parliamentary committee recommended switching to WET, a move being considered by MPs. However, the German occupation switched France to German time, two other occupied territories, Belgium and the Netherlands, did the same, and Spain also switched to CET in solidarity with Germany under the orders of General Franco. In the United Kingdom, from 1940 to 1945 British Summer Time was used in winters, between 18 February 1968 and 31 October 1971, BST was used all year round. In Ireland, from 1940 to 1946 Irish Summer Time was used all year round, between 18 February 1968 and 31 October 1971, Irish Standard Time was used all year round. In Portugal, CET was used in the mainland from 1966 to 1976, the autonomous region of the Azores used WET from 1992 to 1993. Iceland Mykines, Faroe Islands Western Ireland Western Portugal Madeira Canary Islands These areas are located between 7°30′ W and 22°30′ W Areas using UTC+1, See Central European Time

Daylight saving time
–
Daylight saving time is the practice of advancing clocks during summer months by one hour so that evening daylight lasts an hour longer, while sacrificing normal sunrise times. Typically, regions that use Daylight Savings Time adjust clocks forward one hour close to the start of spring, American inventor and politician Benjamin Franklin proposed a form of daylight time in 1784. New Zealander George Hudson proposed the idea of saving in 1895. The German Empire and Austria-Hungary organized the first nationwide implementation, starting on April 30,1916, many countries have used it at various times since then, particularly since the energy crisis of the 1970s. The practice has both advocates and critics, DST clock shifts sometimes complicate timekeeping and can disrupt travel, billing, record keeping, medical devices, heavy equipment, and sleep patterns. Computer software often adjusts clocks automatically, but policy changes by various jurisdictions of DST dates, industrialized societies generally follow a clock-based schedule for daily activities that do not change throughout the course of the year. The time of day that individuals begin and end work or school, North and south of the tropics daylight lasts longer in summer and shorter in winter, with the effect becoming greater as one moves away from the tropics. However, they will have one hour of daylight at the start of each day. Supporters have also argued that DST decreases energy consumption by reducing the need for lighting and heating, DST is also of little use for locations near the equator, because these regions see only a small variation in daylight in the course of the year. After ancient times, equal-length civil hours eventually supplanted unequal, so civil time no longer varies by season, unequal hours are still used in a few traditional settings, such as some monasteries of Mount Athos and all Jewish ceremonies. This 1784 satire proposed taxing window shutters, rationing candles, and waking the public by ringing church bells, despite common misconception, Franklin did not actually propose DST, 18th-century Europe did not even keep precise schedules. However, this changed as rail transport and communication networks came to require a standardization of time unknown in Franklins day. Modern DST was first proposed by the New Zealand entomologist George Hudson, whose shift work job gave him time to collect insects. An avid golfer, he also disliked cutting short his round at dusk and his solution was to advance the clock during the summer months, a proposal he published two years later. The proposal was taken up by the Liberal Member of Parliament Robert Pearce, a select committee was set up to examine the issue, but Pearces bill did not become law, and several other bills failed in the following years. Willett lobbied for the proposal in the UK until his death in 1915, william Sword Frost, mayor of Orillia, Ontario, introduced daylight saving time in the municipality during his tenure from 1911 to 1912. Starting on April 30,1916, the German Empire and its World War I ally Austria-Hungary were the first to use DST as a way to conserve coal during wartime, Britain, most of its allies, and many European neutrals soon followed suit. Russia and a few other countries waited until the year
