![]() Beginning in 2007, DST would now begin at 2 a.m. In the United States, all time zones that observe DST were effectively changed by the Energy Policy Act of 2005. The modified time is called "Central Daylight Time" (CDT) and is UTC−05:00. For other uses, see Central Daylight Time (disambiguation).ĭaylight saving time (DST) is in effect in much of the Central time zone between mid-March and early November. This is reportedly because most people who interact with the town reside in either New Mexico or Colorado. Īlthough legally located within the Central Time Zone, Kenton, Oklahoma-located to the adjacent east of the defined border of the Central and Mountain time zones (at the Oklahoma− New Mexico state line)-unofficially observes Mountain Time. This is due to their close proximity to Columbus, Georgia, which is on Eastern Time. Tennessee: West Tennessee and Middle Tennessee, including the major cities of Nashville and MemphisĪdditionally, Phenix City, Alabama, and several nearby communities in Russell County, Alabama, unofficially observe Eastern Time.Michigan: Gogebic, Iron, Dickinson, and Menominee counties.Kentucky: the western portion of the state, including its three major towns: Bowling Green, Owensboro and Paducah.Indiana: northwest ( Gary) and southwest ( Evansville) regions.Florida: most of Florida Panhandle west of the Apalachicola River Franklin County west of the Apalachicola River and parts of Gulf County are in the Central Time Zone.Texas: all except for El Paso, Hudspeth, and northwestern Culberson countiesįive states are split between the Central Time Zone and the Eastern Time Zone:.South Dakota: eastern half including part of Stanley County.North Dakota: all except for southwest regions, south part of McKenzie County, and the majority of Dunn County and far western Sioux County. ![]() Nebraska: eastern two thirds including the eastern one third of Cherry County.Kansas: all except for Sherman, Wallace, Greeley, and Hamilton counties.The coordinates of a location within each zone are defined as a planar coordinate pair related to the intersection of the equator and the zone’s central meridian, and measured in meters.Įlevation above sea level is a measure of a geographic location’s height.Ten states are contained entirely in the Central Time Zone:įive states are split between the Central Time Zone and the Mountain Time Zone: UTM or Universal Transverse Mercator coordinate system divides the Earth’s surface into 60 longitudinal zones. Negative longitude values correspond to the geographic locations west of the prime meridian (abbrev. Positive longitude values correspond to the geographic locations east Longitude is counted from the prime meridian ( IERS Reference Meridian for WGS 84) and varies from −180° to 180°. Negative latitude values correspond to the geographic locations south of the Equator (abbrev. Positive latitude values correspond to the geographic locations north of the Equator (abbrev. The latitude of the Equator is 0° the latitude of the South Pole is −90° GPS systems widely use coordinates in degrees and decimal minutes, or in decimal degrees. The canonical form of latitude and longitude representation uses degrees (°), minutes (′), and seconds (″). Geographic coordinates (latitude and longitude) define a position on the Earth’s surface. Satellite navigation system (the Global Positioning System). WGS 84 coordinate reference system is the latest revision of the World Geodetic System, which is used in mapping and navigation, including GPS
