Group 0 2020 OOC thread...
So, a decade by definition is a period of 10 years...so by this measure both sides of the argument are correct...and so would someone who said that 2005 to 2014 is a decade!
Really, the argument (and it really is a Facebook/Twitter argument) is whether the "20's" run until Dec 31 2029 or 2030.
And the only reason we even have these social media debates is because there is no Year 0 in our calendar. We went from 1 BCE (or BC) to 1 CE (or AD) and skipped 0. Thus, we had this debate on a much larger scale as Dec 31, 1999 approached. Technically, the new century did not start until Jan 1, 2001 - because 2000 years of CE years did not end until Dec 31, 2000.
Same argument can be used for the decade.
But I fall on the common sense side, especially for decades...they are a simple way of identifying the 10 years that have the same 10's digit! so the 80's (my formative years) were from 1980 to 1989. The new 20's will be from 2020 to 2029.
It's just easier.
