>I must have blinked or something. I can't recall the definition for >"YOK". Please clarify. TIA It's "Y0K," not "YOK," i.e., "Year Zero." It was part of a running joke started with a quotation from Heraclitus about how they knew to count backwards from some time in the future and then how "Y0K" would have affected record-keeping. Of course, the concept of "BC" and "AD" (or, today, "BCE" and "CE") didn't come about for several hundred years "AD." The Romans counted years beginning from the supposed date of the founding of Rome and/or the years of the reign of a particular emperor. Stephen J. Gould's little book, "Rock of Ages," has a great history of calendrics. George Slusher/Eugene, OR gslusher at rio.com
