Time zones help clocks know when it's time to change. Like a giant game of tag, each place on Earth gets its own turn in the sunlight, and clocks follow along! When one part of the world is in the middle of lunch, another might still be having breakfast. A special system called time zones helps clocks everywhere stay accurate by dividing the world into 24 parts, like slices of a pie.
