Time in the United States
Time in the United States, by law, is divided into nine standard time zones covering the states and its possessions, with most of the United States observing daylight saving time for the spring and fall months. The time zone boundaries and DST observance are regulated by the Department of Transportation. Official and precise timekeeping services are provided by two federal agencies: the National Institute of Standards and Technology; the clocks run by these services are kept synchronized with each other as well as with those of other international timekeeping organizations. It is the combination of the time zone and daylight saving rules, along with the timekeeping services, which determines the legal civil time for any U. S. location at any moment. Before the adoption of four standard time zones for the continental United States, many towns and cities set their clocks to noon when the sun passed their local meridian, pre-corrected for the equation of time on the date of observation, to form local mean solar time.
Noon occurred at different times but time differences between distant locations were noticeable prior to the 19th century because of long travel times and the lack of long-distance instant communications prior to the development of the telegraph. The use of local solar time became awkward as railways and telecommunications improved. American railroads maintained many different time zones during the late 1800s; each train station set its own clock making it difficult to coordinate train schedules and confusing passengers. Time calculation became a serious problem for people traveling by train, according to the Library of Congress; every city in the United States used a different time standard so there were more than 300 local sun times to choose from. Time zones were therefore a compromise, relaxing the complex geographic dependence while still allowing local time to be approximate with mean solar time. Railroad managers tried to address the problem by establishing 100 railroad time zones, but this was only a partial solution to the problem.
Weather service chief Cleveland Abbe had needed to introduce four standard time zones for his weather stations, an idea which he offered to the railroads. Operators of the new railroad lines needed a new time plan that would offer a uniform train schedule for departures and arrivals. Four standard time zones for the continental United States were introduced at noon on November 18, 1883, when the telegraph lines transmitted time signals to all major cities. In October 1884, the International Meridian Conference at Washington DC adopted a proposal which stated that the prime meridian for longitude and timekeeping should be one that passes through the centre of the transit instrument at the Greenwich Observatory in the United Kingdom; the conference therefore established the Greenwich Meridian as the prime meridian and Greenwich Mean Time as the world's time standard. The US time-zone system grew from this, in which all zones referred back to GMT on the prime meridian. In 1960, the International Radio Consultative Committee formalized the concept of Coordinated Universal Time, which became the new international civil time standard.
UTC is, within about 1 second, mean solar time at 0°. UTC does not observe daylight saving time. For most purposes, UTC is considered interchangeable with GMT, but GMT is no longer defined by the scientific community. UTC is one of several related successors to GMT. Standard time zones in the United States are defined at the federal level by law 15 USC §260; the federal law establishes the transition dates and times at which daylight saving time occurs, if observed. It is the authority of the Secretary of Transportation, in coordination with the states, to determine which regions will observe which of the standard time zones and if they will observe daylight saving time; as of August 9, 2007, the standard time zones are defined in terms of hourly offsets from UTC. Prior to this they were based upon the mean solar time at several meridians 15° apart west of Greenwich. Only the full-time zone names listed below are official. View the standard time zone boundaries here; the United States uses nine standard time zones.
As defined by US law they are: From east to west, the four time zones of the contiguous United States are: Eastern Time Zone, which comprises the states on the Atlantic coast and the eastern two thirds of the Ohio Valley. Central Time Zone, which comprises the Gulf Coast, Mississippi Valley, most of the Great Plains. Mountain Time Zone, which comprises the states and portions of states that include the Rocky Mountains and the western quarter of the Great Plains. Pacific Time Zone, which comprises the states on the Pacific coast, plus Nevada and the Idaho panhandle. Alaska Time Zone, which comprises most of the state of Alaska. Hawaii-Aleutian Time Zone, which includes Hawaii and most of the length of the Aleutian Islands chain. Samoa Time Zone, which comprises American Samoa. Chamorro Time Zone, which comprises Guam and the Northern Mariana Islands. Atlantic Time Zone, which comprises Puerto Rico and the US Virgin Islands; some United States Minor Outlying Islands are outside the time zones defined by 15 U.

The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti

Louisiana is a state in the Deep South region of the South Central United States. It is the 25th most populous of the 50 United States. Louisiana is bordered by the state of Texas to the west, Arkansas to the north, Mississippi to the east, the Gulf of Mexico to the south. A large part of its eastern boundary is demarcated by the Mississippi River. Louisiana is the only U. S. state with political subdivisions termed parishes. The state's capital is Baton Rouge, its largest city is New Orleans. Much of the state's lands were formed from sediment washed down the Mississippi River, leaving enormous deltas and vast areas of coastal marsh and swamp; these contain a rich southern biota. There are many species of tree frogs, fish such as sturgeon and paddlefish. In more elevated areas, fire is a natural process in the landscape, has produced extensive areas of longleaf pine forest and wet savannas; these support an exceptionally large number of plant species, including many species of terrestrial orchids and carnivorous plants.
Louisiana has more Native American tribes than any other southern state, including four that are federally recognized, ten that are state recognized, four that have not received recognition. Some Louisiana urban environments have a multicultural, multilingual heritage, being so influenced by a mixture of 18th-century French, Spanish, Native American, African cultures that they are considered to be exceptional in the US. Before the American purchase of the territory in 1803, present-day Louisiana State had been both a French colony and for a brief period a Spanish one. In addition, colonists imported numerous African people as slaves in the 18th century. Many came from peoples of the same region of West Africa. In the post-Civil War environment, Anglo-Americans increased the pressure for Anglicization, in 1921, English was for a time made the sole language of instruction in Louisiana schools before a policy of multilingualism was revived in 1974. There has never been an official language in Louisiana, the state constitution enumerates "the right of the people to preserve and promote their respective historic and cultural origins."
Louisiana was named after Louis XIV, King of France from 1643 to 1715. When René-Robert Cavelier, Sieur de La Salle claimed the territory drained by the Mississippi River for France, he named it La Louisiane; the suffix -ana is a Latin suffix that can refer to "information relating to a particular individual, subject, or place." Thus Louis + ana carries the idea of "related to Louis." Once part of the French Colonial Empire, the Louisiana Territory stretched from present-day Mobile Bay to just north of the present-day Canada–United States border, including a small part of what is now the Canadian provinces of Alberta and Saskatchewan. The Gulf of Mexico did not exist 250 million years ago when there was but one supercontinent, Pangea; as Pangea split apart, the Atlantic Ocean and Gulf of Mexico opened. Louisiana developed, over millions of years, from water into land, from north to south; the oldest rocks are exposed in areas such as the Kisatchie National Forest. The oldest rocks date back to the early Cenozoic Era, some 60 million years ago.
The history of the formation of these rocks can be found in D. Spearing's Roadside Geology of Louisiana; the youngest parts of the state were formed during the last 12,000 years as successive deltas of the Mississippi River: the Maringouin, Teche, St. Bernard, the modern Mississippi, now the Atchafalaya; the sediments were carried from north to south by the Mississippi River. In between the Tertiary rocks of the north, the new sediments along the coast, is a vast belt known as the Pleistocene Terraces, their age and distribution can be related to the rise and fall of sea levels during past ice ages. In general, the northern terraces have had sufficient time for rivers to cut deep channels, while the newer terraces tend to be much flatter. Salt domes are found in Louisiana, their origin can be traced back to the early Gulf of Mexico, when the shallow ocean had high rates of evaporation. There are several hundred salt domes in the state. Salt domes are important not only as a source of salt. Louisiana is bordered to the west by Texas.
The state may properly be divided into two parts, the uplands of the north, the alluvial along the coast. The alluvial region includes low swamp lands, coastal marshlands and beaches, barrier islands that cover about 20,000 square miles; this area lies principally along the Gulf of Mexico and the Mississippi River, which traverses the state from north to south for a distance of about 600 mi ) and empties into the Gulf of Mexico. The breadth of the alluvial region along the Mississippi is from 10 to 60 miles, along the other rivers, the alluvial region averages about 10 miles across; the Mississippi River flows along a ridge formed by its own natural deposits, from which the lands decline toward a river beyond at an average fall of six feet per mile. The alluvial lands along other streams present similar features; the higher and contiguous hill lands of the north and northwestern part of the state have an area of more than 25,000 square miles. They consist of prairie and woodl
U.S. Route 24
U. S. Route 24 is one of the original United States highways of 1926, it ran from Pontiac, Michigan, in the east to Kansas City, Missouri, in the west. Today, the highway's northern terminus is in Independence Township, Michigan, at an intersection with I-75 and its western terminus is near Minturn, Colorado at an intersection with I-70; the highway transitions from north -- south to east -- west signage in Ohio. In Colorado, US 24 runs from Interstate 70 from Minturn where it goes through Minturn and continues south to the Continental Divide at Tennessee Pass, it continues south to Johnson Village and joins with U. S. Route 285 northbound to the Trout Creek Pass. After the pass, US 24 separates from US 285 and continues east to Colorado Springs and northeast to Limon, where US 24 joins I-70 for most of the rest of its routing to the Kansas state line; when the United States Highway System was started in 1926, US 24 in Colorado was designated U. S. Route 40S, it began in Grand Junction and went east along the current Interstate 70 corridor to Minturn, from which it follows the current route to Limon.
From Limon east to the Kansas border, the current US 24 was designated U. S. Route 40N. US 40S west of Limon and US 40N east of Limon received the US 24 designation in 1936, when US 24 was extended west from Kansas City, Missouri; the segment between Grand Junction and Minturn was decommissioned in 1975. In Kansas, US-24 enters from Colorado west of Kanorado. US-24 does not meet I-70 again until Kansas City. On December 1, 2008, US 24 was rerouted southward on US 73 to I-70 west of Kansas City, continuing east on I-70 on the final 16 miles in Kansas. US-24 serves Manhattan, as well as the northern sides of Lawrence; the original designation for the current US-24 route in Kansas was U. S. Route 40N, it went from the Colorado border to Manhattan. In 1936, U. S. Route 24 received its current designation after an extension west from Kansas City. In Kansas, US-24 is merged with US-59 from Williamstown to a place in North Lawrence called Teepee Junction. From there it is merged with US-40 until Kansas City.
In Missouri, US 24 serves Kansas City, Buckner, Waverly, Keytesville, Madison, Monroe City and West Quincy. It is concurrent with U. S. Route 65 between Waverly and Carrollton, passing over the Missouri River via the Waverly Bridge when concurrent. After becoming a two-lane road, it is concurrent with Highway 5 in Keytesville, passes by the city of Huntsville before turning into a four-lane highway and crossing U. S. 63 at Moberly. It is concurrent with U. S. Route 36 east of Monroe City and with U. S. Route 61 from south of Palmyra to West Quincy; the segment shared with US 61 is part of the Avenue of the Saints. Along the route within Independence is Museum. In Illinois, U. S. Route 24 runs west across the Quincy Bayview Bridge and east across the Quincy Memorial Bridge over the Mississippi River in Quincy; the cable-stayed Bayview Bridge brings westbound US 24 over the Mississippi River. Eastbound traffic is served by the older Quincy Memorial Bridge; as of 2006, it is the main arterial highway from Quincy northeast to Peoria.
From Quincy to Peoria, the route follows the old Peoria to Quincy stage coach route. John Jacob Astor was the original owner of the tract upon which Astoria was platted in 1836 and served as an important way station on the stage coach route. U. S. 24 travels onto the Shade-Lohman Bridge on interstate 474, it gets off of exit 9. From Peoria, US 24 runs directly east through a number of small towns en route to Indiana and Fort Wayne, the next major metropolitan center. US 24 crosses into Indiana at the state line east of Sheldon. In Indiana, U. S. Route 24 runs east from the Illinois state line to Huntington. At Huntington, U. S. 24 runs to Fort Wayne. The segment of U. S. 24 between Logansport and Toledo, Ohio is part of the Hoosier Heartland Industrial Corridor project of the Intermodal Surface Transportation Efficiency Act. From Fort Wayne, US 24 follows the path of the Maumee River towards Toledo. In Ohio, the roadway enters the state east of Woodburn, near Antwerp. Between the Indiana state line and Toledo, this portion of the roadway is known as the Fort to Port segment of the Hoosier Heartland Industrial Corridor.
Between Napoleon and Toledo, modern US 24 lies north of the Maumee River as a highway built to Interstate Highway standards. Just north of Waterville is the site of the Battle of Fallen Timbers of 1794. General Anthony Wayne after, constructing a trail from Fort Wayne to Defiance and defeated an Indian consortium, thus opening northern Ohio to white settlement. At a point on the Toledo's north side US 24 veers from northeast–southwest to true north–south, turning on to Telegraph Road, while Detroit Avenue continues as a city street that connects to M-125 at the Michigan border; the path through Toledo of US 24 follows the course of old US 25, old US 25 being farther away from the course of north–south I-75. Truncated as a state route, what had been US 24 was renumbered as Ohio State Route 25 where it remained a state highway, US 25 in greater Toledo became US 24. In Michigan, U. S. Route 24 enters from Toledo and serves the city of Monroe and the Detroit Metro Area, where it is known as Telegraph Road.
It continues north through the western edge of Detroit. It passes through Michigan'
Illinois is a state in the Midwestern and Great Lakes region of the United States. It has the fifth largest gross domestic product, the sixth largest population, the 25th largest land area of all U. S. states. Illinois is noted as a microcosm of the entire United States. With Chicago in northeastern Illinois, small industrial cities and immense agricultural productivity in the north and center of the state, natural resources such as coal and petroleum in the south, Illinois has a diverse economic base, is a major transportation hub. Chicagoland, Chicago's metropolitan area, encompasses over 65% of the state's population; the Port of Chicago connects the state to international ports via two main routes: from the Great Lakes, via the Saint Lawrence Seaway, to the Atlantic Ocean and from the Great Lakes to the Mississippi River, via the Illinois Waterway to the Illinois River. The Mississippi River, the Ohio River, the Wabash River form parts of the boundaries of Illinois. For decades, Chicago's O'Hare International Airport has been ranked as one of the world's busiest airports.
Illinois has long had a reputation as a bellwether both in social and cultural terms and, through the 1980s, in politics. The capital of Illinois is Springfield, located in the central part of the state. Although today's Illinois' largest population center is in its northeast, the state's European population grew first in the west as the French settled the vast Mississippi of the Illinois Country of New France. Following the American Revolutionary War, American settlers began arriving from Kentucky in the 1780s via the Ohio River, the population grew from south to north. In 1818, Illinois achieved statehood. Following increased commercial activity in the Great Lakes after the construction of the Erie Canal, Chicago was founded in the 1830s on the banks of the Chicago River at one of the few natural harbors on the southern section of Lake Michigan. John Deere's invention of the self-scouring steel plow turned Illinois's rich prairie into some of the world's most productive and valuable farmland, attracting immigrant farmers from Germany and Sweden.
The Illinois and Michigan Canal made transportation between the Great Lakes and the Mississippi River valley faster and cheaper, new railroads carried immigrants to new homes in the country's west and shipped commodity crops to the nation's east. The state became a transportation hub for the nation. By 1900, the growth of industrial jobs in the northern cities and coal mining in the central and southern areas attracted immigrants from Eastern and Southern Europe. Illinois was an important manufacturing center during both world wars; the Great Migration from the South established a large community of African Americans in the state, including Chicago, who founded the city's famous jazz and blues cultures. Chicago, the center of the Chicago Metropolitan Area, is now recognized as a global alpha-level city. Three U. S. presidents have been elected while living in Illinois: Abraham Lincoln, Ulysses S. Grant, Barack Obama. Additionally, Ronald Reagan, whose political career was based in California, was born and raised in the state.
Today, Illinois honors Lincoln with its official state slogan Land of Lincoln, displayed on its license plates since 1954. The state is the site of the Abraham Lincoln Presidential Library and Museum in Springfield and the future home of the Barack Obama Presidential Center in Chicago. "Illinois" is the modern spelling for the early French Catholic missionaries and explorers' name for the Illinois Native Americans, a name, spelled in many different ways in the early records. American scholars thought the name "Illinois" meant "man" or "men" in the Miami-Illinois language, with the original iliniwek transformed via French into Illinois; this etymology is not supported by the Illinois language, as the word for "man" is ireniwa, plural of "man" is ireniwaki. The name Illiniwek has been said to mean "tribe of superior men", a false etymology; the name "Illinois" derives from the Miami-Illinois verb irenwe·wa - "he speaks the regular way". This was taken into the Ojibwe language in the Ottawa dialect, modified into ilinwe·.
The French borrowed these forms, changing the /we/ ending to spell it as -ois, a transliteration for its pronunciation in French of that time. The current spelling form, began to appear in the early 1670s, when French colonists had settled in the western area; the Illinois's name for themselves, as attested in all three of the French missionary-period dictionaries of Illinois, was Inoka, of unknown meaning and unrelated to the other terms. American Indians of successive cultures lived along the waterways of the Illinois area for thousands of years before the arrival of Europeans; the Koster Site demonstrates 7,000 years of continuous habitation. Cahokia, the largest regional chiefdom and urban center of the Pre-Columbian Mississippian culture, was located near present-day Collinsville, Illinois, they built an urban complex of more than 100 platform and burial mounds, a 50-acre plaza larger than 35 football fields, a woodhenge of sacred cedar, all in a planned design expressing the culture's cosmology.
Monks Mound, the center of the site, is the largest Pre-Columbian structure north of the Valley of Mexico. It is 100 feet high, 951 feet long, 836 feet wide, covers 13.8 acres. It contains about 814,000 cubic yards of earth, it was topped by a structure thought to have measured about 105 feet in length and 48 feet in width, covered an area 5,000 square feet, been as much as 50 feet high, making its peak 150 feet above the level of the pl
Livingston County Courthouse (Illinois)
The Livingston County Courthouse is an historic building and a longtime judicial center for Livingston County, United States. It is located in the county seat of Pontiac; the current Livingston County Courthouse is the third building to carry that name. Construction on the present-day courthouse was completed late the next year; the courthouse was built after fire consumed the second Livingston County Courthouse on July 4, 1874. The plan for the courthouse was selected from a slate of ten candidate plans; the County Board of Supervisors noted at the time that the selected plan "cost more money it was the only one which for size, fire-proof qualities, solidity would answer the purpose, was indeed, in the matter of taste and elegance, much in advance of any other." However, the author of the 1915 The County Archives of the State of Illinois called the building "hardly fireproof". The courthouse clock tower was installed in 1892, it served as the county's primary judicial center until late 2011, when a replacement Law and Justice Center opened across the street, but officials announced plans to preserve the older building.
John C. Cochrane, a Chicago architect designed the Livingston County Courthouse in Second Empire style; the building is symmetrical and rectangular, standing two stories tall. Each of its four corners features a tower and there is a central clock tower topping the building; some architectural elements found on the structure include: quoins, cornices, a mansard roof, belt courses and patterned roof tiles. From the basement to the eaves the building stands 55 feet tall and the clock tower sits at 70 feet above the basement; the Livingston County Courthouse was added to the National Register of Historic Places on November 19, 1986. It was added because it met criteria for inclusion in the areas of politics and government as well as architecture; the building was the seat of judicial activity in Livingston County, Illinois from 1875 until the 21st century, it is a locally excellent example of Second Empire style. 11th Judicial Circuit of Illinois, official site, accessed July 9, 2009
