Happy New Year / Decade?

23:22 on Tuesday Dec 31 2019 as I write this.

Happy New Year – being in Australia, I suppose we are among the first to celebrate the New Year of 2020.

But here is a thought – certainly, it is a new year – who can disagree with that? – but is it also a new decade? Is tomorrow the start of ‘The Twenties’ or do we have to wait until this time next year before the decade kicks in?

There was no year 0 A.D. when Pope Gregory XIII instituted his new calendar in 1582 to replace the increasingly erratic Julian calendar. So, the first decade would have been from year 1A.D. to year 10 A.D. The next decade would have begun in year 11 A.D. and so on. Does that make sense? So, ‘following’ that line of thought, the decade called ‘the Twenties’ should not begin until 01 January 2021.

And yet tomorrow / today is 01 January 2020  and if it sounds like Twenty, looks like a Twenty and appears like a Twenty, surely it is ‘The Twenties’? Am I being a pedant here?

Who cares.  Happy 2020 everyone.
