Why is 2001 and 2002 etc. in the 21st Century and not the 20th?

Answer

To answer this question, you need to think back to your own life. After you were born, (but BEFORE your first birthday...), you were in the 1st year of your life! And when you turned one, you began the second year of your life.

It is the same principle with century numbers. We are always living in the "next" century. In the year 1 to 100, we were living in the first century. But, in the year 101, we were living in the second century.

Same with Millenia! After the year 2000, we began living in the 3rd Millenium!
