Everyone is talking about the end of the decade. Actually, this is the last year of the first decade of the new century/millennium. Why do I say that?
I learned as a child that there is no 0 (zero) year. Why would this make a difference? If there was a zero year, 2009 would have been the last year of the first decade. Without the zero year 2010 is the last year of the first decade. This means the new decade does not start until 2011.
Still not sure you understand?
Count from 0 – 9. How many numbers are there? Ten, right? Now count from 1 – 9. How many numbers are there? Nine. How many years in a decade? Ten.
