Understanding Time Zones and Earth's Rotation

The video explains why different parts of the world experience day and night at different times due to Earth's rotation. It introduces the concept of time zones, which divide the world into 24 regions, each an hour apart. Examples from cities like New York, London, Dubai, and Tokyo illustrate how local times differ globally. The video concludes by highlighting the importance of time zones in keeping track of time relative to daylight and nighttime.
