Understanding Time Zones

Doug discusses why different places on Earth have different times. He uses a story about calling a friend in India to illustrate the concept of time zones. The Earth is divided into 24 time zones, each one hour apart, due to its round shape and rotation. This explains why it's daytime in one place and nighttime in another. Doug also explains smaller time differences, like those between California and Illinois, and introduces the concept of time zones with names like Pacific and Central time. The video concludes with a summary and a preview of the next episode's topics.
