You're right, my math is off. 1900 to 1999 is 100 years. It's just not the same 100 years as the "20th Century." If it's the C&T of the 1900's, OK. But the first "century" started with year 1, not year 0. And so goes the great Millenium controversy - is 2000 the first year of the new Millenium, or the last year of the old one? I still say, the party starts 12/31/1999 and goes through 1/1/2001.
