Which country has the most time zones?

If you were asked to name the country with the most time zones, you would probably reach for a map and point at the biggest thing on it. Good instinct. Wrong answer. The winner is a country you can drive across in a day.

The short answer

France has the most time zones of any country: 12 for most of the year, and 13 when the little North Atlantic territory of Saint-Pierre and Miquelon switches to daylight saving time. Guinness World Records lists France as the record holder. Russia and the United States share second place with 11 each.

The real story

Mainland France itself uses just one time zone, Central European Time, which is UTC+1 (and UTC+2 in summer). The other zones come from France’s overseas territories, scattered across almost every ocean on the planet.

Head west and you reach Saint-Pierre and Miquelon in the North Atlantic, French territory in the Caribbean, and French Guiana in South America. Keep going into the Pacific and you arrive in French Polynesia, home to Tahiti, sitting at UTC−10. Head east instead, through France’s Indian Ocean territories and its southern and Antarctic lands, and eventually you reach Wallis and Futuna in the South Pacific at UTC+12. From one end of the French clock to the other is a spread of 22 hours.

Even the runners-up come with an asterisk. Guinness notes that two of the eleven US zones are unofficial, including one at UTC+12 that covers Wake Island and research bases in Antarctica. France wins without needing any of that sort of help.

That means that on the right day of the year it can be breakfast time in one part of France and late evening in another, and all of it counts as home soil.

Other countries with far-flung territories score highly too. According to timeanddate.com, the United Kingdom and Australia each have 9 time zones once their overseas territories and external islands are included. Russia, by contrast, gets most of its 11 zones from one huge continuous chunk of land, plus the separate Kaliningrad region on the Baltic.

Why people get it wrong

We picture time zones as vertical stripes across a world map, so it seems obvious that the widest country should collect the most stripes. Russia stretches across a huge sweep of Europe and Asia, so it feels like a lock.

The trick is that time zones follow political territory, not just mainland size. France’s colonial history left it with islands and territories dotted around the globe, and every one of them keeps local time. Most people simply forget those places are legally part of France. Add them back in and the small hexagon of mainland Europe suddenly owns more of the world’s clocks than anyone.

“Biggest country on the map? Nah. It’s the one with a croissant in every ocean.”
