After 24 hours, it has completed a full rotation of 360 degrees. To build the time zone map, they studied Earth’s movements.Īs Earth rotates on its axis, it moves about 15 degrees every 60 minutes. In the late 1800s, a group of scientists came up with a new system for time zones. At one point, train stations in the United States alone had to keep up with 75 time zones across the country. Especially as people began to travel across North America by train, the many time zones became difficult to follow. Then, they would go around town and adjust other people’s clocks to make sure they matched.Īs the world became more connected, this grew complicated. One person would make sure the official town clock read noon when the sun was highest in the sky each day. Just over a century ago, towns and cities set their own time. People have lived in different time zones for a long time, but it hasn’t always been as organized as it is today. Since different parts of Earth enter and exit daylight at different times, we need different time zones. Noon would be the middle of the day in some places, but it would be morning, evening, and the middle of the night in others. Imagine if the entire Earth had a single time zone. When your location rotates out of sunlight, you see the sun set. As your location on Earth rotates into sunlight, you see the sun rise. As Earth rotates, different parts of Earth receive sunlight or darkness, giving us day and night. Every 24 hours, the Earth makes a complete rotation. You know our planet is a sphere that spins on an imaginary pole called its axis. To understand time zones, start by thinking about the shape of the Earth. How is that possible? Is it time travel? Of course not! They just live in a different time zone. What time is it where you are? Have you ever traveled to another place and experienced a time change? Maybe you know someone who lives far away and is a few hours ahead of you. All rights reserved.Quick, find the nearest clock.
