where does eastern time zone change to central
Eastern Time Zone The boundary between time zones is set forth in the Code of Federal Regulations, with the boundary between the Eastern and Central Time Zones being specifically detailed at 49 CFR 71.[4]
Eastern Time Zone The Uniform Time Act of 1966 ruled that daylight saving time would run from the last Sunday of April until the last Sunday in October in the United States.[3] The act was amended to make the first Sunday in April the beginning of daylight saving time as of 1987.[3] The Energy Policy Act of 2005 extended daylight saving time in the United States beginning in 2007. So local times change at 2:00 a.m. EST to 3:00 a.m. EDT on the second Sunday in March and return at 2:00 a.m. EDT to 1:00 a.m. EST on the first Sunday in November.[3] In Canada, the time changes as it does in the United States.[4][5]
Daylight saving time The dates on which clocks are to be shifted also vary with location and year, consequently, the time differences between regions also vary throughout the year. For example, Central European Time is usually six hours behind North American Eastern Time, except for a few weeks in March and October/November, while the United Kingdom and mainland Chile could be five hours apart during the northern summer, three hours during the southern summer, and four hours a few weeks per year. Since 1996, European Summer Time has been observed from the last Sunday in March to the last Sunday in October; previously the rules were not uniform across the European Union.[41] Starting in 2007, most of the United States and Canada observe DST from the second Sunday in March to the first Sunday in November, almost two-thirds of the year.[42] Moreover, the beginning and ending dates are roughly reversed between the northern and southern hemispheres because spring and autumn are displaced six months. For example, mainland Chile observes DST from the second Saturday in October to the second Saturday in March, with transitions at 24:00 local time.[43] In some countries time is governed by regional jurisdictions within the country so that some jurisdictions shift and others do not; this is currently the case in Australia, Brazil, Canada, Mexico, and the United States.[44][45]
Eastern Time Zone The boundaries of the Eastern Time Zone have moved westward since the Interstate Commerce Commission took over time-zone management from railroads in 1938. For example, the easternmost and northernmost counties in Kentucky were added to the zone in the 1940s, and in 1961 most of the state went Eastern. In 2000, Wayne County, on the Tennessee border, switched from Central to Eastern.[1] In March 2018, the Florida Legislature passed a bill requesting authorization from Congress for year-round daylight savings time, which would effectively put Florida on Atlantic Standard Time year-round.[2]
Boston Marathon The race's organizers keep a standard time clock for all entries, though official timekeeping ceases after the six-hour mark.
AP Poll The football poll is released Sundays at 2pm Eastern time during the football season, unless ranked teams have not finished their games.
