Interesting Facts

Once you accept that time zones are set by governments rather than by geography, the strange cases stop looking like mistakes. A country can be five zones wide and run on a single clock, an offset can be 45 minutes, and two islands within sight of each other can sit a day apart on the calendar.

Everything collected here is in use today, which is what makes it worth knowing. The Strangest Time Zones in the World is the tour; Countries with Half-Hour Time Zones and The Largest Time Difference on Earth take two of those cases further; Which Country Has the Most Time Zones? has an answer that changes depending on how you count; and What Time Is It at the North and South Pole? deals with the one place on Earth where the question has no natural answer at all.

The Strangest Time Zones in the World Offsets of 45 minutes, a country five geographic zones wide running on a single clock, and other oddities that are all entirely official.
Countries with Half-Hour Time Zones India, Iran, Newfoundland and parts of Australia: who runs 30 or 45 minutes off the hour, and the reasoning behind each choice.
The Largest Time Difference on Earth Twenty-six hours between the two ends of the map, the islands that make it possible, and what it looks like on a calendar.
Which Country Has the Most Time Zones? The answer depends on whether overseas territories count, and the ranking changes completely once they do.
What Time Is It at the North and South Pole? Every meridian meets at the poles, so the clock there is a decision rather than a fact. What the research stations actually use.
