Book Description
The only small, popular book on the important subject of ancient calendars. The study of heavenly cycles is common to most ancient cultures. The ancient Egyptians, Chinese, and Babylonians all tried to make sense of the year. But it fell to the later Mesoamerican Maya to create a series of calendars that could be cross referenced. In doing so, the Maya discovered many strange numerical harmonics. Their lunar calendar was extremely accurate-far more so than the Greek Metonic cycle; they tracked Venus to an accuracy of less than a day in five hundred years and their tables could have been used to predict eclipses seven hundred years in the future. This book will provide a much needed compact guide to the Mayan calendar systems as well as covering the essentials of calendar development throughout the world.

Book Description
Dates form the backbone of written history. But where do these dates come from? Many different calendars were used in the ancient world. Some of these calendars were based upon observations or calculations of regular astronomical phenomena, such as the first sighting of the new moon crescent that defined the beginning of the month in many calendars, while others incorporated schematic simplifications of these phenomena, such as the 360-day year used in early Mesopotamian administrative practices in order to simplify accounting procedures. Historians frequently use handbooks and tables for converting dates in ancient calendars into the familiar BC/AD calendar that we use today. But very few historians understand how these tables have come about, or what assumptions have been made in their construction. The seven papers in this volume provide an answer to the question what do we know about the operation of calendars in the ancient world, and just as importantly how do we know it? Topics covered include the ancient and modern history of the Egyptian 365-day calendar, astronomical and administrative calendars in ancient Mesopotamia, and the development of astronomical calendars in ancient Greece. This book will be of interest to ancient historians, historians of science, astronomers who use early astronomical records, and anyone with an interest in calendars and their development.

Book Description
The adventure spans the world from Stonehenge to astronomically aligned pyramids at Giza, from Mayan observatories at Chichen Itza to the atomic clock in Washington, the world's official timekeeper since the 1960s. We visit cultures from Vedic India and Cleopatra's Egypt to Byzantium and the Elizabethan court; and meet an impressive cast of historic personages from Julius Caesar to Omar Khayyam, and giants of science from Galileo and Copernicus to Stephen Hawking. Our present calendar system predates the invention of the telescope, the mechanical clock, and the concept ol zero and its development is one of the great untold stories of science and history. How did Pope Gregory set right a calendar which was in error by at least ten lull days? What did time mean to a farmer on the Rhine in 800 A.D.? What was daily life like in the Middle Ages, when the general population reckoned births and marriages by seasons, wars, kings'' reigns, and saints' days? In short, how did the world
