The North American Central Time Zone
Central Time Zone
(CT) is a time zone in parts of Canada, the United States, Mexico, Central America, some Caribbean Islands, and part of the Eastern Pacific Ocean. Central Standard Time (CST) is six hours behind Coordinated Universal Time (UTC). During summer most of the zone uses daylight saving time (DST), and changes to Central Daylight Time (CDT) which is five hours behind UTC.

Regions using (North American) Central Time[edit] Canada[edit] Main article: Time in Canada The province of Manitoba
Manitoba
is the only province or territory in Canada that observes Central Time in all areas. The following Canadian provinces and territories observe Central Time in the areas noted, while their other areas observe Eastern Time:

Nunavut
Nunavut
(territory): western areas (most of Kivalliq Region
Kivalliq Region
and part of Qikiqtaaluk Region) Ontario
Ontario
(province): a portion of the northwest bordering southeastern Manitoba, in and around Kenora.

Also, most of the province of Saskatchewan
Saskatchewan
is on Central Standard Time year-round, never adjusting for Daylight Saving Time. Major exceptions include Lloydminster, a city situated on the boundary between Alberta and Saskatchewan. The city charter stipulates that it shall observe Mountain Time and DST, putting the community on the same time as all of Alberta, including the major cities of Calgary
Calgary
and Edmonton. As a result, during the summer, clocks in the entire province match those in Alberta, but during the winter, clocks in most of the province match those in Manitoba. United States[edit] Main article: Time in the United States Nine states are contained entirely in the Central Time Zone:

Alabama Arkansas Illinois Iowa Louisiana Minnesota Mississippi Missouri Wisconsin

Note: Although all of Alabama
Alabama
is legally on Central Time, Phenix City and some of the nearby community of Smiths Station unofficially observe Eastern Time, as these areas are part of the metropolitan area of the considerably larger city of Columbus, Georgia
Columbus, Georgia
in the Eastern Time Zone. Lanett and Valley observe Eastern Time historically because they were textile mill towns and the original home office of their mills was in West Point, Georgia.[1] Seven states are split between the Central Time Zone

Mexico[edit] Main article: Time in Mexico Most of Mexico—roughly the eastern three-fourths—lies in the Central Time Zone, except for six northwestern states (Baja California, Baja California

and Salas y Gómez Island in Chile

uses Central Standard Time during the Southern Hemisphere winter and Central Daylight Time during the Southern Hemisphere summer; the remainder of Chile
Chile
uses Atlantic Standard Time and Atlantic Daylight Time. Central Daylight Time[edit] Daylight saving time
Daylight saving time
(DST) is in effect in much of the Central time zone between mid-March and early November. The modified time is called Central Daylight Time (CDT) and is UTC−5. In Canada, Saskatchewan does not observe a time change. One reason that Saskatchewan
Saskatchewan
does not take part in a time change is that, geographically, the entire province is closer to the Mountain Time Zone's meridian. The province elected to move onto "permanent" daylight saving by being part of the Central Time Zone. The only exception is the region immediately surrounding the Saskatchewan
Saskatchewan
side of the biprovincial city of Lloydminster, which has chosen to use Mountain Time with DST, synchronizing its clocks with those of Alberta. In those areas of the Canadian and American time zones that observe DST, beginning in 2007, the local time changes at 02:00 local standard time to 03:00 local daylight time on the second Sunday in March and returns at 02:00 local daylight time to 01:00 local standard time on the first Sunday in November. Mexico
Mexico
decided not to go along with this change and observes their horario de verano from the first Sunday in April to the last Sunday in October. In December 2009, the Mexican Congress allowed ten border cities, eight of which are in states that observe Central Time, to adopt the U.S. daylight time schedule effective in 2010.
