Stars of Days & Months - The Story of 7 and 12

Why are there 7 days in a week and 12 months in a year? What do stars have to do with it? This book tells you all about 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 the stories they told, but we still tell time the same way. Inside this book are the reasons why.
