Common usage is not consistent. For example, the Twentieth Century is 1901 thru 2000. The 1900s is of course 1900 thru 1999. The first decade of the twentieth century is clearly 2001 thru 2010, while the two-thousand-oughts are 2000 thru 2009. Similarly the Second Millenium is 1001 thru 2000. I'm not sure anyone talks about "the one-thousands". --ms On 02-Jan-20 04:15, William R Somsky wrote:
There is no reason not to declare that the first decade/century/millennium was anomalous and was short one year to make things jibe w/ the common usage that the first year of each following decade/year/millennium is that which ends in 00. Otherwise, if you're being hyper-pedantic, what are you going to do about the skipped days in the changeover from the Julian to Gregorian calendar -- the year that wasn't a full year long?

What's the problem here?
The third decade of the 21st century CE is 2021-2030. The decade called "the 2020s" is 2020-2029.

I’ve heard that, “officially”, the 21st century began on January 1, 2001, not January 1, 2000.
Do those officials (whoever they are) also contend that the Aughts (or whatever they’re called) didn’t start until 2001, so that likewise the Teens didn’t start until 2011 and the Twenties won’t start until a year from now? Or do they say that the last year of each century is also the first year of a new decade?
Sorry if I’m resurrecting a thread from ten or twenty years ago...
