It gives a description of fourteen calendars and how they relate to one another: the present civil calendar (Gregorian)， the recent ISO commercial calendar， the old civil calendar (Julian)， the Coptic and Ethiopic calendars， the Islamic (Moslem) calendar; the Baha’i， the Hebrew (Jewish) calendar， the Mayan calendars， the French Revolutionary calendar， the Chinese calendar， and both the old (mean) and new (true) Hindu (Indian) calendars. This new edition will be a valuable resource for working programmers， as well as a fount of useful algorithmic tools for computer scientists.
