Why do some countries have many time zones?
OR
What are ‘Time Zones’?
उत्तर
Large countries like Russia, Canada, and the United States have vast longitudinal extent. They do not have a single Standard Time for the whole Country. They have many time zones, with each time zone covering about 15° of longitude. The erstwhile Soviet Union had 11 times zones to cover 165° of longitudinal extent. Canada and the United States have five time zones extending from the Atlantic coast of the Pacific coast. There is a time difference of five hours between the two coasts.
