It’s Palindrome Week—and this week is especially auspicious. Each date this week is a palindrome (a word, phrase, or sequence that reads the same backward as forward):
How rare is that? Aziz Inan, an engineering professor at University of Portland who tracks palindromes, told USA Today:
“A five-digit palindrome is not as rare as a seven-digit date palindrome, such as 1/10/2011, or an eight-digit date palindrome such as 01/02/2010. There will be only 26 seven-digit palindromes this century and 12 eight-digit dates … Once you start writing the year as two digits, then things change because those dates occur every century. Today is 5/11/15, but next century there’s also going to be 5/11/15, but it’s going to be the 22nd century instead of the 21st century.”
