A Palindromic Week

A palindrome is a group of numbers or letters that can be written the same way backwards. For example, the word radar is a palindrome, because reversed it is still radar. Every so often the date is a palindrome. One of the best examples was on November 11, 2011 (11/11/11), but the 22nd of that month would have been a palindrome too (11/22/11).

This entire week of 4/13 – 4/19 has an amazing quality: that every single day is a palindrome giving us a palindromic week. Take a look:

4-13-14 – 41314

4-14-14 – 41414

4-15-14 – 41514

4-16-14 – 41614

4-17-14 – 41714

4-18-14 – 41814

4-19-14 – 41914                                                  

                The following day, April 20th, breaks this pattern (42014). The only other palindrome days we will have this year are 4/10, 4/11, and 4/12. This decade is full of palindromic weeks – 2012, 2013, 2014, 2015, 2016, and 2018.

                Granted, these are not entirely true palindrome days, because the year is abbreviated. So far in the 21st century we have had 7 days that were entirely palindromes.

October 2, 2001 – 10022001

January 2, 2010- 01022010

January 10, 2011 – 11022011

November 2, 2011 – 11022011

February 10, 2012 – 2102012

March 10, 2013 – 3102013

April 10, 2014 – 4102014

                Palindrome days are occurring much more frequently lately, because we are in the early part of the 21st century. After the year 2040 these dates become much rarer (in fact there are only 6 entire palindrome days after 2039), because the years do not “flip” as easily. While palindromic days will still happen, having an entire week won’t be possible.
