The Story of Clocks and Calendars

by Betsy & Giulio Maestro

January 1, 2001, will mark the beginning of a new thousand-year period on earth.  How can it be the year 2000? The answer is that it is the year 2000 only on the Gregorian calendar. On the Hebrew calendar, the year will be 5760. On the Muslim calendar, the year will be 1420. And on the Chinese calendar, it will be 4698. So what year is it really? It all depends on what calendar you use and when you started counting the years.

Here is the fascinating story of timekeeping: how, over thousands of years, calendars and clocks came to be.  48 pgs. · Softcover.

Warning: This is a secular book. On pg. 5, there is a mild reference to evolutionary thought.  Otherwise, this is a very informative book on timekeeping and wonderfully illustrated.
