a nova década só começa dia 1.1.MMXXI

A bit of curious information (courtesy Hans Noel): Knowledge is knowing that there was no year 0, so technically, the new decade begins Jan. 1, 2021, not 2020. Wisdom is knowing that we started this system in the middle, it’s socially constructed anyway, and it feels right to treat “1 to 10” as a decade, so that’s what we do.

For all practical purposes, a new decade starts tomorrow.
