Steve,

This sounds interesting, but I have a question.   How does the B.P. system 
deal with specific dates?   How would you refer to 546 BC in a way that an 
exhibit would be accurate year after year?   Surely you would not mix two different 
systems in an exhibition, one for specific dates and one for general ones.
