    Plot twist: Centuries end in “0”, they don’t start in “0”.

    The 21st Century started 1/1/2001.

      Mathematics and languages have different rules.

      In languages it is possible for one century to be a yewa shorter than all the others. Other centuries begin on a year divisible by hundred, but centuries 1–99 and -1–-99 don’t. They are both missing a year, and outside mathematics that’s just fine.

      If almost all native speakers of a language say that a century begins in a year divisible by hundred then that’s how it goes in that language.

      Correct.

      The 1st century started at 1 A.D. and included 100. 2nd century started 101 to 200. Etc etc. If you change the 21st century to be 2000. You would to shift everything down. Eventually making the 1st century 99 years. Or creating a year 0 or using 1BC.
