How's this for a calendrical trifecta: Sunday is Super Bowl Sunday. And it's Groundhog Day. And it's a rare eight-digit palindrome when written as 02/02/2020 — the only one of its kind this century.

And this one occurs twice depending on whether the date is interpreted as US or UK.

"In this century, in the American date system — which is month, day, year — there are 12 eight-digit palindrome dates," Inan said. But "in this century there is only one such palindrome date which is expressed with eight digits, where you have the complete year number on the right" and the month and day can be swapped. (Put another way: Written as MM/DD/YEAR or DD/MM/YEAR, it's still a palindrome. Contrast that with 11/02/2011, which in many foreign notations was written as 02/11/2011.)

That makes Sunday's palindrome unusually cross-cultural. It's written as a palindrome "whether you're in Europe, Asia, America — it happens on the same calendar day, which is February the 2nd," Inan said. Sunday is also the 33rd day of the year, which is followed by 333 more days, he said.

 

I noticed that too

 

There there is:
2020/02/02
which is better for ordering chronologically.

That stands for 2020/Feb/02
