Which Country on the Earth Has The Most Time Zones

Time Zone describes many things, but basically, it is known as the local time of a region. The time zone of the area is defined as the offset or difference from the Coordinated Universal Time (UTF). UTC is a time standard which is within 1 second of mean solar time at 0-degree longitude. Time zone helps in maintaining and regulating time across the world. Countries and regions mostly adopt time zones so that they have to follow the same clock to preserve the smooth working of infrastructure. It is a responsibility of the government of a country to maintain the different time zones in the different sections of the country. Some countries also cover a large area, and there are different times in different sections of the country, for example, France has many regions that lie overseas, and the whole country cannot maintain a single time zone. So the government has officially demarcated the boundaries for 13 different time zones across the country. Some countries cover a larger area than other, so they have different time zones in different parts of the country. The difference between Time Zones has many setbacks. The major setback of time zones is for the travelers. Traveling through different regions, people have to face many problems in maintaining their routines. Many of the people suffer from fatigue as their body clock is not synchronized according to the time of their destination. People who travel to different places sometimes also have to pick a flight at an awkward time to reach their destination at the specific time. Employees that work overseas also have to manage their routine according to the time zone of location their client resides, and it becomes a severe problem to report for duty at an awkward time.

So down below is a list of countries in which there are most time zones:


top countries with most time zones

France secures the first spot in having the most time zones within a single country. France has 13 time zones in different regions of the country. All times zones of France with their specific areas are listed below:
French Polynesia — UTC−10:00
Marquesas Islands — UTC−09:30
Gambier Islands — UTC−09:00
Clipperton Island — UTC−08:00
Guadeloupe, Martinique, Saint Barthélemy, Saint Martin — UTC−04:00 (Atlantic Standard Time)

Kerguelen Islands, Îles Saint-Paul, and Nouvelle-Amsterdam — UTC+05:00
New Caledonia — UTC+11:00
Wallis and Futuna — UTC+12:00

Various regions of France follow the Central European Time which is UTC+01:00 or the Central European Summer Time (UTC+02:00). In most of Metropolitan France, Daylight Saving Time occurs from the very last Sunday of March which continues till the last Sunday of October. Using 13 time zones with the record of having most time zones in a single country, it has several time zones because it also has some regions that lie overseas.
Till 1891, the Metropolitan cities of France followed the time according to the local solar time. But to make a standard time all the French Metropolitan Cities were unified with a standard time zone. This had to be done because due to the different time zones of different Metropolitan cities, there were conflicts in the time management of Railways. There were other issues too, but this major issue led to the unification of time. The time was made the same by Paris Solar Time. France started following the GMT+0 as the official time of the country back in 1911.
The northern region of France started following GMT+2 as the standard time in 1940. GMT+1 is the official time of the significant Metropolitan French Cities. The time zones lie between UTC-10:00 in French Polynesia and UTC+12:00 in the areas of Wallis and Futuna.

Unites States:

top countries with most time zones

On the second rank, Unites States stands with a total of 11 time zones. Across the different regions and territories and cities of U.S., a total of 9 times are followed officially, but the specific areas unofficially follow two other times. A vast area of U.S observes Daylight Saving time in the fall, spring and some of the summer months. The Department of Transportation with the cooperation of National Institute of Standard and Technology and the US Naval Observatory regulates the boundaries of time zones across different parts of the country. The transportation department is given the authority to manage time because they have to face the most trouble caused by the change of time zones in the different section across the country. So they regulate the standards and demarcate the boundaries in which a standard time zone is followed.

The list of official and unofficial time zones followed by the United States is given below:

Baker Island and Howland Island — UTC−12:00 (unofficial)
