The Numerology of 2021

A friend wrote to me:

“I understand the 19th century went from 1789 to 1914 while the 20th century went only from 1914 to 1989, according to the historians.”

Still, maybe

19th century: 1789 — 1913
20th century : 1914 — 2020
21st century : 2021 — for as long as it takes

The digits 2021 look ominous. And interesting things have just started to happen.

Just a thought
