A century is like a giant birthday cake with 100 candles on it. Each candle represents one year, just like you have a birthday every year. When you count all the candles from 1 to 100, you have a century. It’s like counting all the days until you fill up a whole big calendar with 100 pages, each page being one year.
Think of a century as a big, long train with 100 cars. Each car is a year, and they all link together to make the train go far. When the train has all 100 cars, it has traveled a century’s worth of time down the tracks.
You can also imagine a century as a long storybook with 100 chapters. Each chapter tells the story of one year, and when you finish reading all the chapters, you’ve read a century’s worth of stories.
A century can also be like a garden with 100 different flowers. Each flower blooms for a year, and when all the flowers have bloomed, the garden has been alive for a century.
