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
2021 = 43 * 47
