If you're going to be pedantic about the new decade starting in 2021 because "there was no year 0", then you also have to be pedantic about the new decade starting on January 11, 2021, because there were no October 5-14, 1582.
@noelle my argument for why the decade starts on 0, is that my first decade as a baby started at 0. 😅
@noelle but I think Koreans would refute this evidence.
