What are time zones? (Pretend that you are explaining this to an eight-year old.)

Time zones are like invisible lines that separate the world into different "time areas." Imagine that the Earth is a big ball, and as it spins around, different parts of the world get sunlight at different times. This means when it's daytime in one place, it might be nighttime somewhere else. Each time zone usually has a one-hour difference from the next, helping everyone know what time it is to wake up, eat, or play, no matter where they are! Think of it like a giant clock! When you visit your friend in another country, you might have to change your watch because their time could be different. So, if it's lunch at your house, it might be breakfast at your friend's house! It's a bit like a fun game of matching the times to make video calls or plan parties!
