My dictionary defines Millennium as: a thousand years. If we agree that is what a millennium is then this millennium won't end until 12:00 a.m. January 1st, 2001. That will end the passage of one thousand years. When you are born, you start aging. Soon you turn one year old. You will be one year old until the time you turn two and so on. Therefore, when you turn 100, which we all will <g>, you will be 100 for that whole year. Meaning, a century does not end until that last year ends. So, we will not be in the 21st century until the year 2001 either. Just my two cents worth.
