Time zones in the Atlantic

The Atlantic Ocean is between the Americas and Europe and is divided into several time zones. Some of the major time zones in the Atlantic are:

  • UTC-02:00: This time zone is observed in the South Atlantic, including South Georgia and the South Sandwich Islands.
  • UTC-01:00: This time zone is observed in the North Atlantic, including the Azores, the Cape Verde Islands, and the Faroe Islands.
  • UTC+00:00: This time zone is observed in the Mid-Atlantic, including Ascension Island and Saint Helena.

Note that many countries in the Atlantic region observe Daylight Saving Time (DST), which temporarily shifts the standard time in a region by one hour during certain parts of the year. This is done to make better use of sunlight during the longer days of summer. Some Atlantic countries that observe DST include the United Kingdom, Ireland, and Portugal.

The Atlantic Ocean is home to many small islands and territories, many of which have their own time zones. These time zones are often based on the time zone of the nearest major landmass, but they can also be influenced by other factors, such as the time zone of the country that administers the territory.
