Interesting Facts About Time Zones Around the World

Interesting facts about time zones around the world can help students learn how time is measured across different countries. In simple words, time zone refers to a geographic region which follows the same standard time. It is about understanding the Earth’s rotation and how it affects day and night on our planet Earth. Did you know that being of vast size, China only has 1 timezone? Here are more interesting facts about time zones around the world for students. 

Greenland and Britain Share A Time Zone 

Despite Greenland’s remote location between Iceland and Canada, a part of eastern Greenland uses GMT (UTC), the same time zone as Britain. The weather station of Danmarkshavn and the nearby Northeast Greenland National Park, home to only a few human residents, follows this time zone.

Sao Tome and Principe Follows the Same Time Zone as the UK 

Did you know that Sao Tome and Principe, a small and unknown island nation off West Africa, shares the GMT time zone? With about 13,000 tourists per year, the country offers beautiful forests and a slower pace of life, distinct from the rest of the world.

China Follows Only 1 Time Zone Despite its Size

Although China is vast, it follows a single time zone—Beijing Standard Time. This change was made in 1949 to promote national unity. However, this means that in the eastern parts of the country, the sun may not rise until 10 a.m.

France has the Most Time Zones in the World

Despite being smaller than many countries, France leads the world with 12 time zones. This is due to France’s overseas territories scattered across the globe, from French Polynesia to Wallis and Futuna.

You can Gain a Day by Crossing the International Date Line

You can celebrate two birthdays in a row by flying from Samoa (GMT+13) to American Samoa (GMT-11) across the International Date Line, gaining a whole day. This is surely one of the most interesting facts about time zones around the world.

Hawaii and Alaska Share a Time Zone

These two vastly different states in the U.S. share a time zone for half the year, though they couldn’t be more different in terms of climate and geography.

Afghanistan and China have a 3.5 Hour Time Difference 

Afghanistan and China share a short border, yet they have a huge 3.5-hour time difference. Even though the two countries are geographically close, their time zones vary significantly.

Märket Island and Tuba City have Unique Time Zone Rules

Märket Island in the Baltic is split between Sweden and Finland, meaning it uses two time zones. Similarly, Tuba City in the Navajo Nation has different time zone rules within the same town due to different observance of Daylight Saving Time.

The North and South Poles don’t have Official Time Zones

Because all longitude lines converge at the poles, neither the North nor the South Pole has an official time zone. Research stations in these regions follow either their home country’s time zone or the nearest inhabited area’s time zone, or they use UTC.

The Transcontinental Railroad Sparked the Creation of Time Zones in the US

Before the railroad, the US operated on thousands of local time zones. However, with the completion of the Transcontinental Railroad, the need for accurate schedules led railroad companies to lobby for a standardized time system. This resulted in the establishment of four time zones across the country.

Greenwich Mean Time (GMT) is the Universal Standard Time

GMT, which runs along the Prime Meridian (0° longitude), is the starting point for every time zone globally. Although now known as Coordinated Universal Time (UTC), GMT is still commonly used to refer to this standard time.

Arizona and Hawaii don’t Observe Daylight Saving Time

While most of the US follows daylight saving time, Arizona and Hawaii do not. In Arizona, the extreme heat of daylight hours makes it more practical for residents to schedule outdoor activities in the cooler evenings.
