Someone (A.R.) sent me a message saying
It’s the roaring 20s again! Quick, enjoy some alcohol before the economic collapse.
I predict people are going to use “the twenty-twenties” for the decade of the 2020s, and not “the twenties” (as for “the two-thousand[-and]-twenties,” No).
“The twenty-twenties” sounds sleek, futuristic. “The twenties” is already taken. The foregoing reasons are compelling and lead me to the conclusion that “the Twenty-Twenties” is the one.
Also this. Scholars believe Jesus was born in 5 BC, in which case our year “2020” into the 2,025th year anno domini. The number sticklers would say we’re already down to a mere four years , 11 months and some days left in the true “2020s.”
