It's last day of the decade

[CARLOver17]

Sorry for being a party pooper, but Dec. 31, 2009 isn't the last day of the decade.

A decade (or century) doesn't start with a zero, (as in the case of 2010), but with a one (1), or 2011. Hence, Dec. 31, 2010 will be the last day of the decade. and the start of a new decade will be on Jan. 1, 2011.

Happy new year, tsikoteers!!!

Excuse you, but it really was the last day of the decade.

December 31, 2009 was the last day of the 2000s or Aughts/Noughts/Ohs/Naughts/Aughties/Noughties/Naughties/Zeroes. (January 1 2000 - December 31 2009)

With your example, can we say that December 31 2000 was the last day of the nineties?

Milleniums, Centuries and decades start with their first year. Which is 0 and ends with the 9.

In any case, I remember the most this decade are the ff:
- Tsunamis, hurricanes and floods
- 9/11 attacks
- War on Iraq, Afghanistan, Israel, Lebanon, Georgia...
- decade of our mighty Gloria Macapagal Arroyo
- first black-american president
- (something car related) Nissan Philippines' downfall
- my childhood/adolescence
- decade of the new Music revolution
