Countries With Most Time Zones: Countries with more than one time zone highlight their geographical size, overseas possessions, or special political borders. Time zones are measured in terms of Coordinated Universal Time (UTC), and some nations cross various zones because of extensive geography or scattered territories. For example, France’s time zones depend on its colonial legacy, and Russia’s time zones are because to its massive landmass. While countries like Canada and Australia highlight their continental breadth and overseas territories. To learn more, here’s a list of the top 10 countries with the most number of time zones in 2025, according to the World Population Review report.

List Of Top 10 Countries With The Most Time Zones:

1 France 13 Overseas territories worldwide UTC +02:00 (mainland)
2 United States 11 Mainland + overseas territories UTC −04:00 to UTC −10:00
3 Russia 11 Largest landmass, exclaves n/a
4 United Kingdom 9 Overseas territories UTC +01:00 (mainland)

  1. France (13 Time Zones)

France has the most time zones, which is a total of 13. All due to its overseas departments and territories and its claims in Antarctica. Metropolitan France itself is on UTC+1, but its widely spread islands in the Pacific Ocean, the Caribbean Sea, and the Indian Ocean stretch its time zones between UTC -10 and UTC+12. Experts state this geopolitical situation is due to its colonial legacy, which has led France to have the most time zones, with places all over the world.

  1. United States (11 Time Zones)

The U.S. extends across 11 time zones, including both its mainland and overseas possessions like Guam and American Samoa. Its mainland spans six main zones, while the overseas possessions add an additional five, from UTC10 to UTC+12. 

  1. Russia (11 Time Zones)

Alike US, Russia also have 11 time zones across UTC+2 to UTC+12. The largest country in terms of area has broad east-to-west span, which necessitates several time zones for the efficiency of administration. The Kaliningrad exclave further contributes to this diversity as it is cut off from the core region.

  1. Australia (9 Time Zones)

There are 9 time zones in Australia because of the mainland zones and outlying territories like Christmas Island and Norfolk Island. The mainland alone covers three time zones. Additionally, the inclusion of territories in the Indian-Pacific Ocean extends the total time zones. 

  1. United Kingdom (9 Time Zones)

The United Kingdom has 9 time zones, consisting of its overseas territories like the Falkland Islands and British Antarctic Territory. The mainland is in UTC+0 or UTC+1 during daylight saving, but the territories range from UTC-4 to UTC+12.

  1. Canada (6 Time Zones)

Canada's breadth from east to west in North America brings a total of 6 time zones, ranging from Pacific Time (UTC-8) to Newfoundland Time (UTC-3:30). The country’s time zones reflect its vast landmass and regional spread.

  1. Denmark (5 Time Zones)

Denmark's 5 time zones encompass its mainland and far-flung outposts like Greenland and the Faroe Islands. Greenland's landmass contributes the most to its number of time zones, which cover several zones from UTC-4 to UTC+0.

  1. New Zealand (5 Time Zones)

New Zealand consists of 5 time zones, all due to its principal islands and dependencies like the Chatham Islands and the Ross Dependency in Antarctica. The Chatham Islands have UTC+12:45 as a unique 45minute offset.

  1. Brazil (4 Time Zones)

Brazil is the world's largest nation in South America, which occupies 4 time zones in its extended space from UTC-5 to UTC-2. The time zones extend over the mainland and overseas islands.

  1. Mexico (4 Time Zones)

Mexico comprises 4 time zones. It stretches from UTC-8 in the northwest to UTC-6 in the southeast, which showcases the country’s geographical extent.

How Many Time Zones Does India Have? 

India has only one official time zone, which is known as the Indian Standard Time (IST) at UTC+05:30. However, the country covers almost 30 degrees of longitude and is geographically large enough to support more than one time zone. Still, India has only one time zone covering the whole country and its territories. IST is calculated at the 82.5°E longitude near Mirzapur, Uttar Pradesh, and has been followed since 1947. India does not apply any daylight saving time.
