2.22.2022 is not a Palindrome. 2.22.2022 reads 2.20.2222. Palindromes are numbers or letters that read the same backwards as forwards. The name "Hannah" is a example. in 2.22.2222 it will be a palindrome.

Then you change your criteria and eliminate the "20" of 2; then the palindrome exists 2-22-22. It seems contradictory and arbitrary of fitting the data to a belief instead of keeping the same criteria throughout.

But maybe I'm missing something. Could you explain?

From Greek palindromos "a recurrence," literally "a running back." see https://www.etymonline.com/search?q=palindrome.
