Today's date — 02-02-2020 — is not only a palindrome; it is a palindrome of all palindromes. One that applies in all date formats (whether month or day goes first).
According to those in the know, the last time there was such a day (11/11/1111) was 909 (itself a palindrome) years ago. And the next time it will come again is 101 (palindrome) years from now, 12/12/2121.
To make it even more special, today is the 33rd day of the year, and there are 333 more to go.
Happy Palindrome Day!
