The North American 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 (but not all) of the zone uses daylight saving time (DST), and changes to Central Daylight Time (CDT) which is five hours behind UTC.

The following Canadian provinces and territories observe Central Time in the areas noted, while their other areas observe Eastern Time:

Major exceptions include Lloydminster, a city situated on the boundary between Alberta and Saskatchewan.

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.
