Central Daylight Time (CDT)

The CDT is the daylight saving time (also called summertime) of the Central Standard Time (CST). The differences of the several time zones to each other are always specified in relation to the "Coordinated Universal Time" (UTC), the time on the prime meridian (zero longitude). In the summer the clocks are switched ahead by 1 hour.

The Central Daylight Time is consistent with UTC -5 and applies to 3 countries.

Further Countries in the same timezone of UTC -5

Although the timezone is named "Central Daylight Time", it has mostly politcal reasons. It simply means that eg beginning and ending of daylight saving time always uniformly apply here. There are some other countries, in which the clock strikes just the same hour. These countries have the same temporal distance to UTC (Universal Time Coordinated):
