Which Country Has the Most Time Zones?
Interesting Facts
France has the most time zones of any country: 12. Not because of anything in Europe — metropolitan France uses a single offset — but because its overseas territories are scattered across every ocean on Earth. Russia holds a different record with 11 zones on one continuous landmass, and the United States also reaches 11 once its Pacific island territories are counted.
- France: 12 zones — the global maximum, spanning UTC−10 to UTC+12.
- Russia: 11 zones, all contiguous, from Kaliningrad at UTC+2 to Kamchatka at UTC+12.
- United States: 11 zones, including two uninhabited islands at UTC−12 and Wake Island at UTC+12 — a full 24 hours apart.
- The United Kingdom and Australia both reach about 9.
- Counting rules matter: standard offsets or summer offsets, inhabited territories or all of them, Antarctic claims or not.
- At the other extreme, China spans five geographic zones and uses one.
Why the Answer Depends on How You Count
Before the league table, three decisions have to be made, and different sources make them differently:
- Standard or summer offsets? Counting daylight saving variants separately inflates every European total. The convention used here is standard-time offsets only.
- Do uninhabited territories count? Two of the American zones and one French zone have no permanent population.
- Do Antarctic claims count? France, Australia, the UK and others hold claims with assigned times. Most tallies exclude them, since Antarctic sovereignty is suspended by treaty — which is exactly why every research station there picks its own clock (What Time Is It at the North and South Pole?).
Take the common convention — distinct standard offsets, all territories, no Antarctic claims — and the ranking is stable.
France: 12 Zones and Nothing to Do with Europe
Paris sits on Central European Time, UTC+1, along with most of the continent. Every other French offset lies thousands of kilometres away:
| Offset | Territory |
|---|---|
| UTC−10:00 | French Polynesia (Tahiti, Society Islands) |
| UTC−09:30 | Marquesas Islands |
| UTC−09:00 | Gambier Islands |
| UTC−08:00 | Clipperton Island (uninhabited) |
| UTC−04:00 | Guadeloupe, Martinique, Saint-Barthélemy, Saint-Martin |
| UTC−03:00 | French Guiana, Saint-Pierre and Miquelon |
| UTC+01:00 | Metropolitan France |
| UTC+03:00 | Mayotte |
| UTC+04:00 | Réunion |
| UTC+05:00 | Kerguelen and Crozet (French Southern Lands) |
| UTC+11:00 | New Caledonia |
| UTC+12:00 | Wallis and Futuna |
The Marquesas at UTC−09:30 are a rarity in their own right, one of a handful of populated half-hour zones worldwide (see Countries with Half-Hour Time Zones). France is also the only country present on both sides of the Pacific in the same tally: Wallis and Futuna at UTC+12 and French Polynesia at UTC−10 are 22 hours apart, so when a working day is beginning in one it finished the previous afternoon in the other.
Russia: 11 Zones You Can Cross by Train
Russia’s record is arguably the more impressive one, because you can walk or ride from one end of it to the other. The country runs from Kaliningrad at UTC+2 to Kamchatka and Chukotka at UTC+12 — eleven consecutive offsets on a single landmass, with no gaps.
The Trans-Siberian Railway from Moscow to Vladivostok crosses seven of them over six nights. Until 2018, Russian Railways printed every timetable and ticket in Moscow time regardless of where the station actually was, so a passenger boarding in Irkutsk had to subtract five hours from the departure board. The rule was finally dropped on 1 August 2018 in favour of local time at each station.
Russia has also changed its mind repeatedly. In 2010 it consolidated eleven zones into nine to simplify administration; in 2014 it restored all eleven after complaints about mismatched daylight. Individual regions still move: Volgograd shifted from UTC+3 to UTC+4 in 2018, then back to UTC+3 in December 2020 after a referendum. Russia also abolished daylight saving entirely, in two stages, in 2011 and 2014.
The United States: 11, and a Full 24 Hours Wide
Most Americans name four zones, or six if they remember Alaska and Hawaii. The full list is longer:
| Offset | Where |
|---|---|
| UTC−12:00 | Baker Island, Howland Island (uninhabited) |
| UTC−11:00 | American Samoa, Midway, Jarvis, Palmyra |
| UTC−10:00 | Hawaii and the western Aleutians |
| UTC−09:00 | Alaska |
| UTC−08:00 to −05:00 | Pacific, Mountain, Central and Eastern (the mainland four) |
| UTC−04:00 | Puerto Rico, US Virgin Islands |
| UTC+10:00 | Guam, Northern Mariana Islands |
| UTC+12:00 | Wake Island |
Nine of those offsets have permanent residents; the remaining two, UTC−12 and UTC+12, belong to uninhabited islands, which is why some sources put the American total at 9 rather than 11.
Counting all eleven produces a genuine curiosity: Baker Island at UTC−12 and Wake Island at UTC+12 are exactly 24 hours apart. They show the same time on the clock and a different date on the calendar, permanently — a small-scale version of the effect described in What Is the International Date Line? and The Largest Time Difference on Earth.
There is a further wrinkle inside the Hawaii-Aleutian zone. Both halves share UTC−10 in winter, but the Aleutian islands of Alaska observe daylight saving time and Honolulu does not, so for eight months of the year the two parts of a single named zone are an hour apart. The mainland picture is in Time Zones in the United States Explained.

| Country | Zones | Range | Note |
|---|---|---|---|
| France | 12 | UTC−10 to +12 | Overseas territories in every ocean |
| Russia | 11 | UTC+2 to +12 | All contiguous |
| United States | 11 | UTC−12 to +12 | Spans a full day |
| United Kingdom | 9 | UTC−8 to +6 | Pitcairn to Diego Garcia |
| Australia | 9 | UTC+6:30 to +11 | Includes Cocos, Christmas and Norfolk Islands |
| Canada | 6 | UTC−3:30 to −8 | Most on a single landmass after Russia |
| Denmark | 5 | UTC−4 to +1 | Counting Greenland and the Faroe Islands |
| Brazil, Mexico, Chile, New Zealand, Kiribati | 3–4 each | — | Kiribati straddles the date line |
Sydney is on one of Australia’s three mainland zones, but the country’s real total climbs once the Indian Ocean territories are added, along with oddities like Lord Howe Island, whose clocks move by only 30 minutes for daylight saving instead of a full hour (Time Zones in Australia Explained). Canada earns its place with the half-hour Newfoundland zone (Time Zones in Canada Explained), and the UK’s nine come entirely from overseas territories, since the country itself uses one (Time Zones in the United Kingdom Explained).
The Opposite Question: Fewest Zones for the Most Land
A country can also be remarkable for how few zones it uses. China spans roughly 60 degrees of longitude — geographically five hourly zones — and runs the whole territory on a single offset, UTC+8, set to Beijing. In the far west of Xinjiang this puts the sun almost two hours out of step with the clock, and an unofficial local time an hour behind the national standard circulates in parallel.
India does something similar across nearly 30 degrees of longitude with one half-hour offset (Time Zones in India Explained), and Greenland, despite being the world’s largest island, manages with only a handful. The trade-off is always the same: a single clock simplifies administration and national life at the cost of an increasingly artificial relationship with daylight. Some of the strangest results are collected in The Strangest Time Zones in the World.
Frequently Asked Questions
Which country has the most time zones?
France, with 12. Metropolitan France uses only one, UTC+1, but its overseas departments and territories occupy eleven further offsets spread from French Polynesia at UTC−10 to Wallis and Futuna at UTC+12.
How many time zones does Russia have?
Eleven, from Kaliningrad at UTC+2 to Kamchatka and Chukotka at UTC+12. That is the largest number on a single continuous landmass. Russia briefly reduced the count to nine between 2010 and 2014 before restoring all eleven.
Does the United States really have 11 time zones?
Yes, once territories are included: six across the fifty states, plus Puerto Rico and the US Virgin Islands at UTC−4, Guam and the Northern Marianas at UTC+10, Wake Island at UTC+12, and the uninhabited Baker and Howland Islands at UTC−12. Only four zones cover the contiguous mainland.
Why does China have only one time zone?
It is a political decision made in 1949 to unify the country on Beijing time. Geographically China spans about five hourly zones, so western regions such as Xinjiang experience sunrise and sunset roughly two hours later on the clock than the offset would naturally suggest.
Which two places in the same country are furthest apart in time?
Baker Island and Wake Island, both American, at UTC−12 and UTC+12 — a difference of exactly 24 hours. Among inhabited places, French Polynesia and Wallis and Futuna are 22 hours apart, both under French administration.
