Keeping this in consideration, which country has most time zones?
France
Furthermore, which country has the fewest time zones? If we consider all offsets (including non-whole-hour ones), then the following time zones are shared by the fewest (for me, “fewest” will be up to 3) countries (including overseas dependencies and territories): UTC-12:00: United States. UTC-11:00: New Zealand, United States. UTC-10:00: France, New Zealand, United
Simply so, how many countries have multiple time zones?
24 countries
Why do some countries have more than one timezone?
If we had one single time zone for Earth, noon would be the middle of the day in some places, but it would be morning, evening, and the middle of the night in others. Since different parts of Earth enter and exit daylight at different times, we need different time zones.
