This week is palindrome week—every date reads the same forwards and backwards. 4/12/14, 4/13/14, 4/14/14... you get the point. Just like words and phrases can be palindromes—mom, racecar, level, live not on evil—so too can numbers. The palindrome has a long history that goes all the way back to the ancient Greeks, who would inscribe palindromic phrases on fountains. One of the most popular fountain inscriptions was "wash the sin as well as the face." Although that phrase isn't a palindrome in English, it is one in Greek.
Palindrome week is only really celebrated in the United States, as it's the only country that uses the mm-dd-yyyy format when writing out dates. Most countries around the world use the dd-mm-yyyy style, although China and Japan are notable for using yyyy-mm-dd. In any case, Twitter has been abuzz with tweets about the week-long holiday. Some have taken to Twitter to celebrate the wordsmith holiday.
Happy Palindrome Week! Did you know every date this week reads the same forwards and backwards? Mind = blown! http://t.co/Cp10CvYXyY
