Provinces of Iran
–
Iran is subdivided into thirty one provinces, each governed from a local center, usually the largest local city, which is called the capital of that province. The provincial authority is headed by a Governor-General, who is appointed by the Minister of the Interior subject to approval of the cabinet, from 1960 to 1981 the governorates were raised to provincial status one by one

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

Iran
–
Iran, also known as Persia, officially the Islamic Republic of Iran, is a sovereign state in Western Asia. Comprising a land area of 1,648,195 km2, it is the second-largest country in the Middle East, with 82.8 million inhabitants, Iran is the worlds 17th-most-populous country. It is the country with both a Caspian Sea and an Indian Ocean coastline. The countrys central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz, Tehran is the countrys capital and largest city, as well as its leading economic and cultural center. Iran is the site of to one of the worlds oldest civilizations, the area was first unified by the Iranian Medes in 625 BC, who became the dominant cultural and political power in the region. The empire collapsed in 330 BC following the conquests of Alexander the Great, under the Sassanid Dynasty, Iran again became one of the leading powers in the world for the next four centuries. Beginning in 633 AD, Arabs conquered Iran and largely displaced the indigenous faiths of Manichaeism and Zoroastrianism by Islam, Iran became a major contributor to the Islamic Golden Age that followed, producing many influential scientists, scholars, artists, and thinkers. During the 18th century, Iran reached its greatest territorial extent since the Sassanid Empire, through the late 18th and 19th centuries, a series of conflicts with Russia led to significant territorial losses and the erosion of sovereignty. Popular unrest culminated in the Persian Constitutional Revolution of 1906, which established a monarchy and the countrys first legislative body. Following a coup instigated by the U. K. Growing dissent against foreign influence and political repression led to the 1979 Revolution, Irans rich cultural legacy is reflected in part by its 21 UNESCO World Heritage Sites, the third-largest number in Asia and 11th-largest in the world. Iran is a member of the UN, ECO, NAM, OIC. Its political system is based on the 1979 Constitution which combines elements of a democracy with a theocracy governed by Islamic jurists under the concept of a Supreme Leadership. A multicultural country comprising numerous ethnic and linguistic groups, most inhabitants are Shia Muslims, the largest ethnic groups in Iran are the Persians, Azeris, Kurds and Lurs. Historically, Iran has been referred to as Persia by the West, due mainly to the writings of Greek historians who called Iran Persis, meaning land of the Persians. As the most extensive interactions the Ancient Greeks had with any outsider was with the Persians, however, Persis was originally referred to a region settled by Persians in the west shore of Lake Urmia, in the 9th century BC. The settlement was then shifted to the end of the Zagros Mountains. In 1935, Reza Shah requested the international community to refer to the country by its native name, opposition to the name change led to the reversal of the decision, and Professor Ehsan Yarshater, editor of Encyclopædia Iranica, propagated a move to use Persia and Iran interchangeably

Regions of Iran
–
Historically and geographically Iran has been divided into a number of different regions. In 2014, Iran was administratively divided into five regions, in 1937 the territory of Iran was divided into 10 administrative regions, Region 1, Region 2, Region 10, etc. For example, Region 7 or Seventh Province corresponded to present-day Fars Province per the Territorial Subdivision Act of 1316 Š. /1937, irans thirty-one provinces were divided into five regions on 22 June 2014, based on a decision of Ministry of Interior. In the division, the adjacency, geographical location and similarities of the provinces were considered, the Constitution of Iran does not provide for regions and they are not the constituent units of the country, but exist purely for the convenience of governmental administration. Also, it now provides a level where provinces can discuss their problems among themselves. The intention was for each region to have regularly scheduled meetings of the constituent provinces Governors-general, the host province would provide the chairman of each meeting. A regional secretariat would be established in the city of the main province of each region. Histories, travel books and economic analyses often refer to less formal, more historical or geographical, the borders of these are not fixed and often have changed over time, and even overlapped at the same time

Capital (political)
–
A capital city is the municipality exercising primary status in a country, state, province, or other region, usually as its seat of government. A capital is typically a city that encompasses the offices and meeting places of its respective government. In some jurisdictions, including countries, the different branches of government are located in different settlements. In some cases, a distinction is made between the capital and the seat of government, which is in another place. The word capital derives from the Latin caput, meaning head, in several English-speaking states, the terms county town, county seat, and borough seat are also used in lower subdivisions. In unitary states, subnational capitals are known as administrative centres. The capital is often, but not necessarily, the largest city of its constituent, historically, the major economic centre of a state or region often becomes the focal point of political power, and becomes a capital through conquest or federation. Examples are Ancient Babylon, Abbasid Baghdad, Ancient Athens, Rome, Constantinople, Changan, Ancient Cusco, Madrid, Paris, London, Moscow, Beijing, Tokyo, Vienna, and Berlin. Some of these cities are or were also religious centres, e. g. Constantinople, Rome, Jerusalem, Ancient Babylon, Moscow, Belgrade, Paris, and Peking. A capital city that is also the economic, cultural. The convergence of political and economic or cultural power is by no means universal, traditional capitals may be economically eclipsed by provincial rivals, e. g. Nanking by Shanghai, Quebec City by Montreal, and numerous US state capitals. The decline of a dynasty or culture could also mean the extinction of its city, as occurred at Babylon. Although many capitals are defined by constitution or legislation, many long-time capitals have no legal designation as such, for example Bern, Edinburgh, Lisbon, London, Paris, are located in or near them. In Canada, there is a capital, while the ten provinces. The states of such countries as Mexico, Brazil, and Australia all have capital cities, for example, the six state capitals of Australia are Adelaide, Brisbane, Hobart, Melbourne, Perth, and Sydney. In Australia, the capital cities is regularly used, to refer to the aforementioned state capitals plus the federal capital Canberra and Darwin. Abu Dhabi is the city of the Emirate of Abu Dhabi. In unitary states which consist of multiple constituent countries, such as the United Kingdom or the Kingdom of Denmark, the national capitals of Germany and Russia, the Stadtstaat of Berlin and the Federal City of Moscow, are also constituent states of both countries in their own right

Yasuj
–
Yasuj is a city in and the capital of Kohgiluyeh and Boyer-Ahmad Province, Iran. At the 2006 census, its population was 96,786, Yasuj is an industrial city in the Zagros Mountains of southwestern Iran. The term Yasuj is also used to refer to the entire region, Yasuj has both a sugar processing plant and a coal-burning powerplant that generates electricity for the area. The people of Yasuj speak Luri Language, the area of Yasuj has been settled since as early as the Bronze Age. Findings include the Martyrs Hills, the Khosravi Hill from the Achaemenian period, the ancient site of Gerd, the Pataveh bridge, and the Pay-e Chol cemetery. Yasuj is the place where Alexander III of Macedon and his Macedonian forces stormed the Persian Gates, the Yasuj Museum, which opened in 2002, displays coins, statues, pottery, and bronze vessels recovered from surrounding archaeological sites. Yasuj was called Tal-e Khosrow in the last century.2 billion and it will produce petrol, gasoil, kerosene, furnace oil, liquefied gas, asphalt, and sulfur.

Counties of Iran
–
The counties of Iran, also called shahrestan, are administrative divisions of larger provinces. The word shahrestan comes from the Persian words shahr and stān, county, therefore, is a near equivalent of shahrestan. Iranian counties are divided into one or more bakhsh, or districts, a typical county includes both cities and rural agglomerations, which are groupings of adjacent villages. One city within the county serves as the capital of that county, in 2005, Iran had 324 shahrestans. To better understand these subdivisions, the table is useful. Assume that province P is divided into two counties, A and B, county A has 3 districts, Central, X, and Y. The Central district is the district that contains City M, the capital of the county, each district contains one or more cities and/or one or more RAs. The minimal county consists of one city as the only district, named Central. The county B in the table is of such type

Iran Standard Time
–
Iran Standard Time or Iran Time is the time zone used in Iran. Iran uses a UTC offset UTC+03,30, IRST is defined by the 52.5 degrees east meridian, the same meridian which defines the Iranian calendar and is the official meridian of Iran. Between 2005 and 2008, by decree of President Mahmoud Ahmadinejad and it was reintroduced from 21 March 2008. Iran is unusual in that the dates of DST transitions arent based on a such as the third Monday in September. So in most countries, DST transitions occur on the same every year

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
