One made the point, "The century is already one tenth over."
I am one who believes the new decade begins in twelve months. Am I wrong?

(Along with the rest of us old fogeys who insist that things like decades, centuries,
and millenia begin with the year one, not the year zero.)
In 525 A.D., at the behest of the Pope, a monk named Dionysius Exiguus
retrofitted the calendar starting the count from the (estimated) moment of Jesus' birth.
He inadvertently omitted the year 0, which is
mathematically necessary to begin a count of time.
At the moment of a man 's birth, he is
0 years old; he is
not then 52 weeks old while the umbilical cord is cut.
Accordingly, the applicable history of the count was inconsistent with the mathematical necessity
of counting time from 0 (the same way that [in America] we count that this year is 0 days,
0 weeks, etc. old + a few hours).
