Map showing world time zones

When you wonder which countries have the most time zones, it’s likely you think about the largest countries in the world. After all, the bigger a country is, the more time zones it falls in, right? Well, yes, to a certain degree. But that’s not the only factor.

Some countries have a large number of time zones due to their size. Russia and the United States, for example, are two of the largest countries in the world by area. However, other countries, such as France and the UK, are much smaller but consist of several overseas territories.

Let’s take a look at which countries have the most time zones (including those in overseas territories).

France – 13 timezones

With 13 time zones (including its territory in Antarctica), France has the most time zones of any country in the world. Metropolitan France has a land area of only 551,695 km² but Overseas France includes islands in the Indian, Atlantic and Pacific Oceans.

Central European Time (CET) is Metropolitan France’s standard time, but Central European Summer Time (CEST) is used during Daylight Saving Time. Metropolitan France observes Daylight Saving Time, which is when clocks are advanced during the warmer months so that darkness falls later in the day. The clocks go forward on the last Sunday of March and go back again on the last Sunday of October.

Denmark – 5

The main territory of Denmark uses UTC+01:00 (CET) as standard time and UTC+02:00 Daylight Saving Time. Most of Greenland (including the inhabited areas on the south and west coasts) uses UTC−03:00.

In 2023, Denmark changed its standard time to standard time as UTC+1, effectively ending a law that had been in place since 1893. The law had previously linked Denmark’s time to the Earth’s rotation. However, as the rotation isn’t completely regular, it would regularly offset the time.
