Today is a most-glorious, super rare palindrome day.What makes this palindrome day so rare is that it works globally – as in, for Americans who write MMDDYYYY, as well as for other places that write DDMMYYYY, including countries like Brazil, Egypt, Germany, India, Italy, United Kingdom, etc. It also works for YYYYMMDD,which is popular in Canada, China, Japan, Lithuania, etc.

So, this should probably be called “Universal Palindrome Day” because it is a palindrome irrespective of the endianness (big, little, or middle) that is used in various countries.A universal palindrome like this will be the only one this century!The last eight-digit palindrome like this was 11/11/1111, 909 years ago. The next one is closer; just 101 years away, on 12/12/2121. After that, it will be a long haul to 03/03/3030.
