Calendrical Calculations - Softcover

'... this book must surely become the standard work on calendar conversions. No historian, chronologist or recreational mathematician should be without it.' E. G. Richards, Nature

'... a really attractive book, not only for specialists such as mathematicians, astronomers or computer scientists, but also for historians or for any person interested in the cultural aspects of science.' Antonio F. Rañada, European Journal of Physics

'... a splendid book, of interest to astronomers and computer scientists, and to anyone concerned with the role of science in the cultural evolution of mankind.' Antonio F. Rañada, European Journal of Physics

'This is a fascinating book to dip into, as well as being a powerful reference work assembling a rich collection of historical, astronomical and computational 'calendar' facts. If you have funds set aside for coping with the millennium bug why not spend a little of them on a copy?' William Wynne Willson, The Mathematical Gazette

The purpose of this book is to present in a unified, completely algorithmic form, a description of thirteen 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 (virtually identical) 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. Easy conversion among these calendars is a by-product of the approach, as is the determination of secular and religious holidays. Calendrical Calculations makes accurate calendrical algorithms readily available for computer use. This volume will be a valuable resource for working programmers, as well as a fount of useful algorithmic tools for computer scientists.
