Therefore, the first millennium didn't end until a thousand years later, on Jan. 1, 1001. The staff of the Herald-Leader knows this. But in beginning our millennium coverage this year instead of next, we, like most other media, chose to disregard it. If you're a calendrical puritan, please don't be offended. And remember that time doesn't always lend itself to standard measure.
Some days disappear.
Some seconds tick faster than others. The site, maintained by Craig Copi, a researcher at Case Western Reserve University, makes it clear that, although time marches on, it's marching to the beat of its own drummer. And the cadence depends on whose calendar you choose. For just one example, recall the heady days of the French Revolution, which had its own calendar. Each month had three weeks.
