Time Zones play a crucial role in maintaining global synchronisation, affecting everything from international trade to travel and communication. While most countries operate within one or two time zones, some nations span vast geographic areas or possess overseas territories, necessitating the management of multiple time zones.
France leads the world with 12 Time Zones, primarily due to its numerous overseas departments and territories. Russia and the United States follow closely, each encompassing 11 Time Zones owing to their expansive mainland regions and distant holdings.
Why Time Zones Matter
A Time Zone is a geographic region that observes a uniform standard time for legal, commercial, and social purposes. Most time zones are defined by their offset from Coordinated Universal Time (UTC), such as UTC+5:30 for India. The global system of time zones ensures synchronisation across countries and continents, especially in sectors like aviation, international trade, and broadcasting.
Several factors contribute to a country having multiple time zones:
- Large east-west landmass (e.g., Russia, USA)
- Overseas territories scattered across the globe (e.g., France, UK)
- Seasonal changes due to Daylight Saving Time (DST)
- Administrative and political divisions
List of Countries With Most Time Zones 2025
Time Zones are established based on one or more deviations from Coordinated Universal Time (UTC). In certain regions, these deviations vary according to specific dates due to the implementation of daylight saving time (DST). As a result, such regions may alternate between time offsets throughout the year. The range of UTC offsets extends from UTC−12:00 to UTC+14:00, commonly measured in full-hour increments. However, a few regions, such as India (UTC+5:30), South Australia (UTC+9:30), and Nepal (UTC+5:45), follow non-standard offsets of 30 or 45 minutes.
The table below includes the List of Countries With Most Time Zones 2025:

Top Countries With the Most Time Zones (2025)
- France – 12 Time Zones: France surprisingly tops the list, not due to the size of its mainland, but because of its numerous overseas departments and territories spread across the globe. These include territories in the Caribbean, Indian Ocean, Pacific Ocean, and even Antarctica.
- Time zones: UTC−10:00 to UTC+12:00
- Russia – 11 Time Zones: As the largest country in the world by area, Russia spans 11 time zones from its western exclave of Kaliningrad to the eastern edge of Kamchatka. Unlike France, all of Russia’s time zones exist within its mainland territory.
- Time zones: UTC+02:00 to UTC+12:00
- United States – 11 Time Zones: The United States covers a significant expanse and includes several unincorporated territories, which contribute to its 11 time zones.
- Time zones: UTC−12:00 to UTC+12:00
- Antarctica – 9 Time Zones: Antarctica is unique because it doesn’t have a permanent population, yet hosts various research stations operated by different countries. Each station uses the time zone of the country that runs it or the supply base it connects with.
- Time zones: UTC−03:00 to UTC+12:00
- United Kingdom – 9 Time Zones: Despite being relatively small in size, the UK has numerous overseas territories that contribute to its broad time zone coverage.
- Time zones: UTC−08:00 to UTC+06:00

- Time zones: UTC+05:00 to UTC+11:00
- Canada – 6 Time Zones: Canada spans from the Atlantic Ocean to the Pacific, resulting in six different time zones. Unlike France or the UK, Canada does not have overseas territories, so all time zones are domestic.
- Time zones: UTC−08:00 to UTC−03:30
- Denmark – 5 Time Zones: Denmark’s mainland may follow just one time zone, but its autonomous territories, including Greenland and the Faroe Islands, span several others.
- Time zones: UTC−04:00 to UTC+01:00
- New Zealand – 5 Time Zones: New Zealand includes several island dependencies, which extend its time zone reach.
- Time zones: UTC−11:00 to UTC+13:00
- Brazil – 4 Time Zones: Brazil spans four time zones across its continental mass and distant islands. It’s the largest country in South America and follows Brasília Time as the standard.
