Gene, Dionysius wasn't "fixing" nothin' ... he was inventin'! You suppose the people living in 400 BC had a calendar on the wall that counted backwards? In the fifth century, man was keeping time to some different drummer. King Gregory decided out of the blue we needed to mark time based on Christ, and set poor Dionysius to document it. Without the foresight to see how cool it is for the calendar to roll from 1999 to 2000, ol' Denys did what any sane sixth century monk would have done, he started counting from one. It happens all the time. You don't have a dozen eggs until you have the twelfth one. You don't have a thousand years until the thousandth year is done. We are almost done with the one thousand nine hundred ninety ninth year. When the two thousdandth year has passed, we will have marked off two thousand years of our modern calendar. Not until.
