~ALGORITHM~

Today is Thursday! A rare date it is! It’s a palindrome date. 

A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward. 

Thursday is 6-10-2016, a string of numbers that make it a palindrome day.

Because date formats vary from country to country, not all dates that are be considered palindromic in one kind of date format are Palindrome Days in another. For instance, July 10, 2017 or 7-10-2017 is a palindromic date in the m-dd-yyyy format, but isn’t if you write the date as mm-dd-yyyy (07-10-2017); as dd-mm-yyyy (10-07-2017) or as yyyy-mm-dd (2017-07-10).

The word “palindrome” was coined by the English playwright Ben Jonson in the 17th century from the Greek roots palin (πάλιν; “again”) and dromos (δρóμος; “way, direction”).

The longest palindromic word in the Oxford English Dictionary is the onomatopoeic tattarrattat, coined by James Joyce in Ulysses (1922) for a knock on the door. The Guinness Book of Records gives the title to detartrated, the preterite and past participle of detartrate, a chemical term meaning to remove tartrates.

 

HAPPY PALINDROME DAY!
