When was the beginning of the twenty first century -
11:59.59 P.M. December 31, 1999,
or
12:00.01 A.M. on January 1, 2000?
__________
Neither.
Contrary to what most people think, the first day of the 21st century will be January 1, 2001, not January 1, 2000. The beginning of a century will start with the year one, not the year zero."
