Why is 2000 not the 21st century?
The year 2000 is special--even though it isnt the start of the 21st century--because it is a leap year. A fairly precise correction to the Gregorian calendar debuted in 1582, and stated that a century year will only be a leap year if it is evenly divisible by 400--which is true for Y2K.
