About CDT – Central Daylight Time

Central Daylight Time is the time zone of the central US and Canada, as well as Mexico and most of Central America. It is five hours behind UTC and is observed during the summer months, between March and November. Sometimes the zone is referred to as CDST – Central Daylight Saving Time Zone. In the winter CDT becomes CST – Central Standard Time.

Countries using CDT:

CDT is observed in the US, Canada, Mexico, Belize, Costa Rica, Guatemala, El Salvador, Nicaragua, Panama and Honduras i.e. all Central American countries. In the US it is only the states in the central US that observes CDT, from Wisconsin in the West to Tennessee in the East, and from Michigan in the North to Florida in the South. Similarly, only Canadian provinces in the middle of the country observe CDT. All of Mexico observes CDT, except the North West corner of the country.

Example of states observing Central Daylight Time:

US: Alabama, Iowa, Louisiana, Texas, Nebraska, Oklahoma, Illinois and many more.

Canada: Manitoba, Ontario (most parts), Saskatchewan (only Creighton and Denare Beach)

Mexico: Chiapas, México, Oaxaca, Yuca tán, San Luis Potosi and more.

Daylight Saving Time

CDT is the daylight saving time of Central Standard Time. There are only a handful of exceptions in this time zone that do not observe DST, so it is advisable to always check the exact location (e.g. using our time zone converter) instead of relying on time zone abbreviations.



About GMT - Greenwich Mean Time

GMT, or Greenwich Mean Time, is the zero when it comes to time zones – they are all counted from the zero meridian that runs through the village of Greenwich.

Countries:

While both the UK and Portugal are officially on GMT you need to pay attention to whether they are actually observing it or are using their own. Britain in the summer for example use British Summer Time – which is different than GMT.

Common cities using GMT:

London, Lisbon, Dublin, Edinburgh

Daylight Saving Time and summer time:

GMT does not observe DST as it is the zero hour time zone – it never changes.
