That's exactly what me'n John B keep saying. Of course, *A* millennium ends every year. but *THE* millennium, i.e. the third thousand years of the Christian/Gregorian calendar, starts as you say, 12:00 a.m. January 1st, 2001. If what David says is correct, they still wouldn't mark the passage of a year until the END of that year, so if we're talking 2000 years since the birth of Christ, we're talking the end of the year 2000. Man has shown no propensity thoughout history to count any other way. At least not until computer geeks talking binary and array index zero as the first element and all that. <g>
