What the heck.  Yes, I have such a program, although it is not polished
in any means.  It knows of some 60 different calendars and converts from
one to the other.  It is essentially without documentation.  If you are
(or anybody is) interested, send me mail.  It is in pascal for the CDC
Cyber series (including machine code), but I am in the process of
converting it to C.  So if you can wait; wait; (but don't hold your breath).
