So is 2010 a new decade, or not?? Apparently not. Some say 2011 is the start of the new decade. First of all I thought it was a load of rubbish, but now........ well I'm not so sure. The argument is..... the first year was 1 AD (as there was no year zero), therefore 10 AD was the last year of the first decade, making 11 AD the first year of the second decade. Moving forward 2000 years (or 200 decades) 2011 will be the first year of the next decade. Sooooo, that also means 1999 wasn't the end of the 20th century, and 2000 wasn't the beginning of the 21st?!?!? ALSO and most shocking, 2000 wasn't the beginning of the new millenium, 2001 was!!! We all celebrated one year too early??? WTF! Surely this isn't correct. Or is it just me who didn't know?! Will someone please have a word with somebody!
