Question

Why do some countries have more than one time zones?

Answer 1

Countries with extensive east-to-west territories experience varying times of sunrise and sunset across their regions due to Earth’s rotation. To align local time with daylight hours, these nations adopt multiple time zones. For example, Russia spans 11 time zones, while the United States covers six. Conversely, countries like China and India, despite their vast land areas, use a single time zone for political and administrative simplicity.
