Artikelbeschreibung vom Verkäufer

Paperback. Time feels simple until you start asking questions. Why does a year have 365 days? Why does the Moon change shape every night? And why do some festivals move across the calendar while others stay fixed? Across the world, people have looked at the same sky and created very different ways to measure time, each one shaped by observation, culture and need.This book takes young readers on a fascinating journey through time, sky and human ingenuity to uncover the hidden logic behind calendars.Follow Arjun and Navya as simple questions lead to big discoveries. Through conversations, stories and clear explanations, readers explore how the Sun, the Moon and the Earth create cycles that don't fit neatly together. Along the way they learn why a year is not exactly 365 days, why a month is not always a month and why no single calendar can perfectly match the sky.The 25 ideas are organised into six arcs that take readers from confusion to clarity.The Confusion opens with the question every child has asked. Why does Diwali fall on a different date every year? The answer turns out to be anything but simple.Reading the Sky travels back to the beginning, when the sky was the only clock humans had. The Moon made months. The Sun made years. And the two refused to agree.Building Calendars follows the great civilisations of Egypt and Rome as they tried to pin time down, each making brilliant and imperfect attempts to match the sky to human life.Fixing Time traces the extraordinary moments when humans intervened. Ten days were erased from the calendar. Railways forced the world to agree on a single time. Leap years were calculated to fractions of a day.The Core Conflict gets to the heart of the matter. Lunar calendars, solar calendars and lunisolar calendars all solve the same problem in different ways. None of them is wrong. None of them is complete.The Solution reveals the deepest secret in the history of timekeeping. A nineteen year cycle discovered by a Greek astronomer that quietly solved the problem every calendar had been trying to fix for thousands of years.Perfect for readers aged 10 to 18, this book combines storytelling with science to make complex ideas easy to understand without oversimplifying them.Inside you will discover: Why lunar and solar cycles don't matchHow different calendars handle the same mismatchThe real reason festivals shift datesHow humans turned observation into systemsWhy every calendar is both correct and incompleteThis is not just a book about dates and numbers. It is a story about how humans tried to make sense of the sky and in doing so revealed different ways of seeing the world.If you have ever wondered how time is measured or why calendars look the way they do, this book will change how you see every date on the page.
