And old chestnut...
It all goes bask to a monk called Dionysius Exiguus who, in 525, introduced the BC/AD system, initially in order to calculate Easter.
His calendar went straight from BC-1 to AD+1 there was never an AD-0. So, mathematically the first decade ran 10 years to end December 2010. AD1 AD2 AD3 AD5 AD5 AD6 AD7 AD8 AD9 AD10 =10 YEARS.
Therefore, I maintain the last century ended on December 31st 2000 and not December 1999. Of course a decade can be any 10-year period but if calculating from 1st January 2010, then we still have 12 months to go.
