The '''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]]. Time in the zone is [[UTC−06|six hours]] behind [[Coordinated Universal Time]] ([[Greenwich Mean Time]] - GMT). During [[daylight saving time]] (DST), time in the zone is [[UTC−05|five hours]] behind GMT.
The North American '''Central Time Zone''' ('''CT''') is a [[time zone]] in parts of [[Canada]], the [[United States]], [[Mexico]], [[Central America]], and some [[Caribbean Islands|Caribbean islands]].<ref>{{Cite web |title=Central Time – CT Time Zone |url=https://www.timeanddate.com/time/zones/ct#:~:text=The%20term%20Central%20Time%20(CT,switches%20between%20CST%20and%20CDT. |access-date=November 22, 2023 |website=timeanddate.com |language=en}}</ref>

In parts of that zone (20 states in the US, three provinces or territories in Canada, and several border municipalities in Mexico), the Central Time Zone is affected by two time designations yearly: '''Central Standard Time (CST)''' is observed from the first Sunday in November to the second Sunday in March. It is [[UTC−06:00|six hours]] behind [[Coordinated Universal Time]] (UTC) and designated internationally as UTC−6.<ref>{{cite web |url=https://www.bts.gov/explore-topics-and-geography/geography/geospatial-portal/history-time-zones-and-daylight-saving |title=History of Time Zones and Daylight Saving Time (DST) |publisher=United States Department of Transportation Bureau of Transportation Statistics |date=January 17, 2023 |access-date=December 28, 2023}}</ref> From the second Sunday in March to the first Sunday in November the same areas observe [[daylight saving time]] (DST), creating the designation of '''Central Daylight Time (CDT)''' which is [[UTC−05:00|five hours]] behind UTC and known internationally as UTC−5.<ref>{{Cite web|title=Central Time (CST/CDT) {{!}} GMT|url=https://greenwichmeantime.com/time-zone/usa/central-time/|website=greenwichmeantime.com|language=en|access-date=May 22, 2020}}</ref>

Ten states are contained entirely in the Central Time Zone:
The Central Time Zone is the second most populous in the US after the [[Eastern Time Zone]]. Many states straddle time zone boundaries.
* [[Alabama]]

* [[Alabama]]: Although all of Alabama is legally on Central Time, [[Phenix City, Alabama|Phenix City]] and the surrounding communities of Smiths Station, Valley, and Lanett unofficially observe Eastern Time, as these areas are part of the media market and metropolitan area of the considerably larger city of [[Columbus, Georgia]] in the Eastern Time Zone.<ref>{{cite web|url=http://archive.decaturdaily.com/decaturdaily/news/060813/zones.shtml |title=Parts of Eastern Alabama split between 2 time zones |publisher=Archive.decaturdaily.com |date=2006-08-13 |accessdate=2013-11-04}}</ref>

* [[Louisiana]]
* [[Louisiana]]
* [[Michigan]]: All of Michigan observes Eastern Time except the four [[Upper Peninsula of Michigan|Upper Peninsula]] counties ([[Gogebic County, Michigan|Gogebic]], [[Iron County, Michigan|Iron]], [[Dickinson County, Michigan|Dickinson]], and [[Menominee County, Michigan|Menominee]]) that border [[Wisconsin]]. Generally, other westernmost counties from this area such as [[Ontonagon County, Michigan|Ontonagon]] unofficially observe Eastern Time.

The other 252 counties of Texas (including Culberson County) MUST observe Central Time according to both Acts of Congress and the [[U.S. Department of Transportation]]. -->
* [[Wisconsin]]
* [[Wisconsin]]

Five states are split between the Central Time Zone and the [[Mountain Time Zone]]:
* [[Kansas]]: all except for [[Sherman County, Kansas|Sherman]], [[Wallace County, Kansas|Wallace]], [[Greeley County, Kansas|Greeley]], and [[Hamilton County, Kansas|Hamilton]] counties
* [[Nebraska]]: eastern two thirds including the east part of [[Cherry County, Nebraska|Cherry County]]
* [[North Dakota]]: all except for southwest regions, south part of [[McKenzie County, North Dakota|McKenzie County]], and the majority of [[Dunn County, North Dakota|Dunn County]] and far western [[Sioux County, North Dakota|Sioux County]]

Additionally, [[Phenix City, Alabama]], and several nearby communities in [[Russell County, Alabama]], unofficially observe Eastern Time. This is due to their close proximity to [[Columbus, Georgia]], which is on Eastern Time.<ref>{{Cite web|url=http://legacy.decaturdaily.com/decaturdaily/news/060813/zones.shtml|title=Parts of Eastern Alabama split between 2 time zones|access-date=March 22, 2009|archive-date=March 10, 2016|archive-url=https://web.archive.org/web/20160310233009/http://legacy.decaturdaily.com/decaturdaily/news/060813/zones.shtml|url-status=dead}}</ref>

=== Central America ===
[[Mexico City]], which is coterminous with the Federal District (''[[Mexican Federal District#Federal District|Distrito Federal]]''), also uses Central Time.
Out of the seven countries comprising [[Central America]], all but one use Central Standard Time year-round:
*[[Belize]], [[Costa Rica]], [[El Salvador]], [[Guatemala]], [[Honduras]], and [[Nicaragua]].<ref name="factbook2023"/>


[[Panama]], which recognizes Eastern Standard Time (UTC−5) year round, is the exception.<ref name="factbook2023">{{Citation |title=Panama |date=November 14, 2023 |url=https://www.cia.gov/the-world-factbook/countries/panama/ |work=The World Factbook |access-date=November 22, 2023 |publisher=Central Intelligence Agency |language=en}}</ref>
In [[Nayarit]], however, only the municipality of [[Bahia de Banderas]] uses Central Time.


===Central America and Caribbean Islands===
==Central Daylight Time==
{{Redirect|Central Daylight Time}}
[[Belize]], [[Jamaica]], [[Costa Rica]], [[El Salvador]], [[Guatemala]], [[Honduras]], and [[Nicaragua]] all use Central Standard Time year round.
[[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]].{{fact|date=August 2024}}


In the United States, all time zones that observe DST were effectively changed by the [[Energy Policy Act of 2005]]. Beginning in 2007, DST would now begin at 2 a.m. (02:00) on the second Sunday in March instead of the first Sunday in April, moving the time from 2 to 3 a.m. (i.e., from 02:00 to 03:00). Additionally, DST would end at 2 a.m. (02:00) on the first Sunday in November instead of the last Sunday in October, moving the time from 2 to 1 a.m. (i.e., from 02:00 to 01:00).{{fact|date=August 2024}}
===Eastern Pacific islands and other areas===

==Central Daylight 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 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 [[Energy Policy Act of 2005|this change]] and observes their {{lang|es|[[Daylight saving time in Mexico|''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.
At the time, Mexico decided not to go along with [[Energy Policy Act of 2005|this change]] and observed their ''[[Daylight saving time in Mexico|horario de verano]]'' ("summer schedule") 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 US daylight time schedule effective in 2010. In October 2022, however, CDT was used in Mexico for the last time after DST was abolished. The US is also seeing traction in the same direction, with the [[Sunshine Protection Act]] that proposes legislation that would permanently end the switching of times and make daylight saving time permanent.<ref>{{cite web |url=https://www.congress.gov/bill/117th-congress/senate-bill/623 |title=S.623 - Sunshine Protection Act of 2021 |work=US Congress |date=March 16, 2022 }}</ref>

Observance of DST
DST is observed in some of this time zone.

The North American Central Time Zone (CT) is a time zone in parts of Canada, the United States, Mexico, Central America, and some Caribbean islands.[1]

In parts of that zone (20 states in the US, three provinces or territories in Canada, and several border municipalities in Mexico), the Central Time Zone is affected by two time designations yearly: Central Standard Time (CST) is observed from the first Sunday in November to the second Sunday in March. It is six hours behind Coordinated Universal Time (UTC) and designated internationally as UTC−6.[2] From the second Sunday in March to the first Sunday in November the same areas observe daylight saving time (DST), creating the designation of Central Daylight Time (CDT) which is five hours behind UTC and known internationally as UTC−5.[3]

Regions using Central Time

[edit]

Canada

[edit]
Main article: Time in Canada

The province of 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:

Also, most of the province of Saskatchewan is on Central Standard Time year-round, never adjusting for Daylight Saving Time. One major exception includes Lloydminster, a city whose borders overlap both Alberta and Saskatchewan. The city charter[4] stipulates that it shall observe Mountain Time and DST, putting the community on the same time as all of Alberta (UTC−7) in the winter, and in time with Saskatchewan (UTC−6) during the summer.

United States

[edit]
Main article: Time in the United States

Ten states are contained entirely in the Central Time Zone:

Five states are split between the Central Time Zone and the Mountain Time Zone:

Five states are split between the Central Time Zone and the Eastern Time Zone:

Additionally, Phenix City, Alabama, and several nearby communities in Russell County, Alabama, unofficially observe Eastern Time. This is due to their close proximity to Columbus, Georgia, which is on Eastern Time.[5]

Although 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.[6] This is reportedly because most people who interact with the town reside in either New Mexico or Colorado.[6][7]

Mexico

[edit]
Main article: Time in Mexico

Most of Mexico—roughly the eastern three-fourths—lies in the Central Time Zone, except for five northwestern states (Baja California, Baja California Sur, Sinaloa, Sonora, and most of Nayarit) and one southeastern state (Quintana Roo). It is known locally as the Zona Centro.[8]

The federal entities of Mexico that observe Central Time:

Central America

[edit]

Out of the seven countries comprising Central America, all but one use Central Standard Time year-round:

Panama, which recognizes Eastern Standard Time (UTC−5) year round, is the exception.[10]

Central Daylight Time

[edit]
"Central Daylight Time" redirects here. For other uses, see Central Daylight Time (disambiguation).

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.[citation needed]

In the United States, all time zones that observe DST were effectively changed by the Energy Policy Act of 2005. Beginning in 2007, DST would now begin at 2 a.m. (02:00) on the second Sunday in March instead of the first Sunday in April, moving the time from 2 to 3 a.m. (i.e., from 02:00 to 03:00). Additionally, DST would end at 2 a.m. (02:00) on the first Sunday in November instead of the last Sunday in October, moving the time from 2 to 1 a.m. (i.e., from 02:00 to 01:00).[citation needed]

At the time, Mexico decided not to go along with this change and observed their horario de verano ("summer schedule") 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 US daylight time schedule effective in 2010. In October 2022, however, CDT was used in Mexico for the last time after DST was abolished. The US is also seeing traction in the same direction, with the Sunshine Protection Act that proposes legislation that would permanently end the switching of times and make daylight saving time permanent.[11]
