A dose of reality, please!
Too many are confused or misguided, so please allow me to set the record straight: we did not close the books on another decade on December 31, 2009.
Yes, we talk about decades like The Sixties, The Seventies, etc... and in those terms we imagine them as:
- The Sixties = 1960-1969
- The Seventies = 1970-1979
... and so on.
In that sense, one would be correct. However, in pure terms, decades begin with a 'one' and end with a 'zero'.
Sure, The Sixties may have started with 1960. But The Sixties, The Seventies, etc... are cultural references, much like describing a period of one's life as middle age even though that time frame may not be the midpoint of one's existence.
Think of it this way:
- Go back to the beginning. Year One. 1 AD... or, 1 CE. That was the first year of the first decade... and the first century... and the first millennium... of Anno Domini or The Common Era.
- 10 AD/CE was the tenth year of that decade. Therefore, January 1, 11 AD/CE would be Day One of the second decade in this example.
- Moving forward... January 1, 2001 was the first day of the first year of the first decade of the 21st Century and of the Third Millennium of Anno Domini/Common Era.
Thus it follows that the next decade begins with January 1, 2011.
Am I too picky? Possibly. But I like to deal in facts.
