One of the triplets messaged me this morning:
Dad, do you realize that 2019 was over 4 years ago??? I FEEL SO OLD!!!
.....she's 12...
2019 was 5 years ago.
Actually February, 2018 was five years ago. December, 2019 was 4.16 years ago which rounds nicely to four years.

(And, of course, both are
over four years ago. )
