Palindromes are usually considered as Palindrome words or sentences, but like in this case, can also be dates
 
This millennium, there would be a total of 36 such dates. While 10/02/2001 was the first, todays’ date, 01/02/2010, is the second such date of this millennium. The next Palindrome day will come comes next year on November 2, that is, 11/02/2011.
 
Interestingly, the Palindrome day is only for countries like America, where the mm/dd/yy system for dates is used. For rest of the world, where day/month/year format is used, today’s date is 02/01/2010.
However, these countries have a greater chance to celebrate Palindrome day, as they will get 60 such opportunities in this millennium.
