Some of us don't have a problem with the notion that the first
century, which wasn't even called that while it was happening, was a
bit shorter than the others. (Strictly speaking, due to various
calendar reforms, centuries have been of several different lengths.)

Seems pretty straightforward to me. One conception says that all of
the years of the century have the same thousands and hundreds digit
(and the same high-order Roman numerals), while the other says that
99% of them do, but the last one is different and shares these digits
with 99% of the next century.
I tend to wonder whether this has ever *not* been a bone of
contention. Based on
Several dissertations have appeared in the public journals on the
question, whether the year 1800 begins the nineteenth century. In
1700 there were many papers on the same subject; but it is
sufficient to consider that centuries are counted like everything
else, from one to a hundred, and therefore it is 1801 that must
begin the new century. The only thing that could occasion this
error is, the transition from 17 to 18 hundreds. It has appeared
to many people that this is changing the century.
_The Philosophical Magazine_, 2/1800
It is a singular circumstance that Dryden, as well as some other
eminent men of that day, should have follen into the errour
respecting the beginning of the century, which has found some
partisans in our own time; conceiving that the seventeenth century
closed on the 24th of March, 1699, and that the new century began
on the following day: in conformity to which notion a splendid
Jubilee was celebrated at Rome in the year 1700. By this kind of
reckoning, the second century began in the year 100 and the first,
in opposition to the decisive evidence furnished by the word
itself, consisted of only _ninety-nine_ years!

Prose Works of John Dryden_, 1800
it was in dispute at the beginning of the eighteenth and nineteenth
centuries, as it clearly was at the beginning of the twentieth and
twenty-first.
