The 20 Facts
Fact 1: France Used Its Own Time Until 1911
France refused to adopt Greenwich Mean Time for 27 years after the 1884 International Meridian Conference. It finally gave in with a law that never mentioned Greenwich — it simply said French time was "Paris Mean Time minus 9 minutes 21 seconds" .
Fact 2: Nepal Is 15 Minutes Ahead of India
The smallest time zone difference between two neighboring countries is 15 minutes. India uses UTC+05:30 and Nepal uses UTC+05:45 .
Fact 3: China Has Only One Time Zone
China spans five geographic time zones but uses only one: Beijing Time (UTC+08:00). In western Xinjiang, the sun can rise at 10:00 AM .
Fact 4: The Diomede Islands Are 21 Hours Apart
Big Diomede (Russia) and Little Diomede (US) are just 2.4 miles apart but separated by 21 hours. When it is Saturday on one, it is Sunday on the other .
Fact 5: You Can Celebrate New Year's Eve Twice
In Tweed Heads (New South Wales) and Coolangatta (Queensland), Australia, you can celebrate New Year's Eve, walk across the border, and celebrate again an hour later .
Fact 6: Kiribati Is the First Country to See the New Year
Kiribati's Line Islands use UTC+14:00, making them the first places on Earth to welcome each new day and each new year .
Fact 7: There Is a 26-Hour Time Difference on Earth
The largest time difference between two places is 26 hours, between Baker Island (UTC−12:00) and the Line Islands (UTC+14:00) .
Fact 8: Russia Has 11 Time Zones

Fact 9: France Has the Most Time Zones
Including overseas territories, France has 12 time zones — more than any other country .
Fact 10: The Poles Have No Time Zone
No time zone is assigned to the North or South Pole. All lines of longitude converge there, so the poles are technically in all time zones at once .
Fact 11: Arizona and Hawaii Skip Daylight Saving
Arizona (except the Navajo Nation) and Hawaii do not observe daylight saving time. Arizona skips it because of desert heat; Hawaii skips it because it is near the equator .
Fact 12: The Navajo Nation Observes DST Inside Arizona
Arizona does not observe DST, but the Navajo Nation within it does. The Hopi Reservation inside the Navajo Nation does not. This creates nested time zones .
Fact 13: Britain's Railways Created Standard Time
Britain's railway companies adopted Greenwich Mean Time in the 1840s to make timetables work. The Great Western Railway led the way in 1840 .
Fact 14: The 1884 Conference Chose Greenwich
The International Meridian Conference of 1884 chose Greenwich as the prime meridian by a vote of 22 to 1. San Domingo (the Dominican Republic) cast the only "no" vote .
Fact 15: Daylight Saving Time Was a Wartime Measure
DST was introduced during World War I to save coal. Germany was the first country to adopt it in 1916 .
Fact 16: Farmers Opposed Daylight Saving Time
Contrary to myth, farmers fiercely opposed DST. Their schedules were based on sunrise and sunset, not the clock .
Fact 17: The ISS Uses UTC
Astronauts on the International Space Station use Coordinated Universal Time (UTC). They experience 16 sunrises and sunsets every day .
Fact 18: A Mars Day Is 39 Minutes Longer
A day on Mars — called a sol — lasts 24 hours, 39 minutes, and 35 seconds. Engineers at JPL shift their schedules by 39 minutes each day during the first 90 sols of a Mars mission .
Fact 19: Swatch Tried to Abolish Time Zones
In 1998, the Swatch Group launched Swatch Internet Time, dividing the day into 1,000 .beats with no time zones. It was quietly discontinued around 2001 .
Fact 20: France Tried Decimal Time
During the French Revolution, France introduced decimal time — a 10-hour day, 100-minute hour, and 100-second minute. It was abandoned after 17 months .
