Oh, I don't think so. LOL
Actually, 2000 is the LAST year of the 20th 
century. 2001 is the FIRST year of the 21st 
century. See how it works: 

Add a dozen cups of flour. You dip 12 times, this 
includes the 12th cup, which is the LAST cup of 
the 12 you need to make a "dozen." See? Hence 
you need 1000 years to make a millenium, 100 years
to make a century - counting 1-100, 101-200, 
201-300, okay?
