Central America

Belize, Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua all use Central Standard Time year-round.

Eastern Pacific islands and other areas

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 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−05:00. In Canada, Saskatchewan does not observe a time change. One reason for Saskatchewan's lack of a time change is that the 105th parallel of longitude, the start point for the Mountain Time Zone, divides the province into approximately equal portions. 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 bi-provincial 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 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. October 2022, was the last CDT in Mexico, as they abolished DST.
