There is one by Lance Latham called "Standard C Date/Time Library; Programming the World's Calendars and Clocks" ISBN 0-87930-496-0 While I am quite sure this book can be shot down for many reasons, it does attempts to cover many calendars and their revisions. It also attempts to do this in such a detail that a software implementation is possible and then do it. Target is in C and there is a companion CDROM. Just to give you a hint, it describes subjects such as the Khwarizmian Calendar (structure 12x30 + 5 days) and Alexandrian Style calendars (structure 12x30 + 5 or 6 days, forming a quad of 365 + 365 + 366 + 365 years, thus including leap year). etc. The book has a rather lengthy reference list in the back and discusses to some extent the mappings. It attempts to use Julian dates as reference between various calender dates. If you wish to implement a varity of calendars, this book should be a good startingpoint, if nothing else.
