Does the first year of a decade count as part of it?
Some just refer to it as transitional year.

The first year of a decade obviously counts as part of it....the question is what year do you start (and end) the decade.
Does it run from XXX0 to XXX9....or does it run from XXX1 to XXY0?
The argument for the earlier is that this decade is the 2010s (running from 2010 to 2019), and the next decade would be the 2020s (running from 2020 to 2029).
The argument for the latter is that the first year is year 1 (not year 0), so the first decade would have run from year 1 to year 10 and this decade should run from 2011 to 2020.
