|Observance of DST|
|DST is observed in some of this time zone.|
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 TimeEdit
The province of Manitoba is the only province or territory in Canada that observes Central Time in all areas, although if bill 205 of the Manitoba Legislative Assembly passes, Daylight Saving Time will be abolished. 
The following Canadian provinces and territories observe Central Time in the areas noted, while their other areas observe Eastern Time:
- Nunavut (territory): western areas (most of Kivalliq Region and part of Qikiqtaaluk Region)
- Ontario (province): a portion of the northwest bordering southeastern Manitoba, in and around Kenora.
Also, most of the province of 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 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.
Nine states are contained entirely in the Central Time Zone:
Note: Although all of Alabama is legally on Central Time, Phenix City and 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 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.
Six states are split between the Central Time Zone and the Mountain Time Zone:
- Kansas – all, except for Sherman, Wallace, Greeley, and Hamilton counties
- Nebraska – eastern two thirds
- North Dakota – all, except for southwest regions and south part of McKenzie County, plus the majority of Dunn County and far western Sioux County
- Oklahoma – all, except for Kenton
- South Dakota – eastern half
- Texas – all, except for El Paso and Hudspeth counties
Five states are split between the Central Time Zone and the Eastern Time Zone:
- Florida – Florida Panhandle below Alabama border (west of the Apalachicola River) and the Dry Tortugas National Park in Monroe County west of the Florida Keys
- Indiana – northwest and southwest regions
- Kentucky – western half
- Michigan – Gogebic, Iron, Dickinson, and Menominee counties
- Tennessee – West Tennessee and Middle Tennessee
Most of Mexico—roughly the eastern three-fourths—lies in the Central Time Zone, except for six northwestern states (Baja California, Baja California Sur, Chihuahua, Sinaloa, Sonora, and *most of Nayarit) and one southeastern state (Quintana Roo).
The federal entities of Mexico that observe Central Time:
- Colima – except for the Revillagigedo Islands, in which the inner islands use Mountain Time and the outer island uses Pacific Time
- Mexico City
- Nayarit – *only the municipality of Bahía de Banderas, rest of the state uses Mountain Time
- Nuevo León
- San Luis Potosí
- State of Mexico
Eastern Pacific islands and other areasEdit
The Galápagos Islands in Ecuador uses Central Standard Time all year-round; the remainder of Ecuador uses Eastern Standard Time. Both Easter Island 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 uses Atlantic Standard Time and Atlantic Daylight Time.
Central Daylight TimeEdit
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−05:00. In Canada, Saskatchewan does not observe a time change. One reason that 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 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 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.
