Book excerpt: Astronomy is the study of objects in space. Astronomy is also in the origins of how we tell time today. A year is the time it takes the earth to travel once around the sun. Long ago, people looked up to the sky for how to divide the year. Why are there 7 days in a week and 12 months in a year? What do astronomy and stars have to do with it? Long ago, people looked up at the night sky. They made up stories to explain the speckled dots of lights. The ancients divided up the year into weeks and days. They assigned "stars" to days and groups of stars to months. We may not know all their stories and beliefs, but we still tell time the same way. Inside this book are reasons why.
