Mapping Time - The Calendar and Its History - E.G. Richards - Oxford Univ. Press

Mapping Time Hardback book in very good condition. Oxford University Press 1998. 450 pages. Some inner pages shown. Only a small portion of the table contents is shown in the photos. Lots of great illustrations. All pages are clean and intact. Spine is strong. No writing or highlighting noted. No dogeared pages. Dust cover is good with no tears, only mild shelf edge wear. This book fully addresses the phenomenon we know as the calendar. From the fundamentals of astronomy to the world's ancient time-keeping schemes, from the development of the modern-day calendar to the precise calculation of what happens when (as in, how does one arrive at the date for Easter Sunday?). This is a thorough discussion of the calendar from both the historical and contemporary perspectives.
