Question

1. How many countries have more than one time zone and why?​

Answer 1

Answer:

Some of the countries are so big, i.e. they cover a land area, so large, that more than one set of 15 degrees of longitudes intersect the country, thus resulting in two or three or more time zones in that country. This is why some countries have more than one time zones.

There are 24 countries which have more than one time zone, with the reasons being divided into 2 categories: The country has overseas territories in different time zones, such as France, which has 13 time zones, even though the mainland has only 1.
