Palindrome Week Returns!



The above image is from last year, but you get the idea.

You should feel very balanced this week. Why? Because it’s palindrome week!  July 10 – July 19, 2017 are all Palindrome Days (m/dd/yy).

A palindrome exists when letters, numbers, or phrases are the same forward and backward. For example, the words “racecar” and “kayak” are palindromes along with the phrase “Was it a car or a cat I saw?”

The dates this week are all five-digit palindromes. Today is 7-10-17; it’s the same if you read it forward and backward.

Depending on date formats, palindromic dates can be rare. Aziz S. Inan, an electrical engineering professor at the University of Portland, Portland, U.S.A. has calculated that in the mm-dd-yyyy format, Palindrome Days tend to occur only in the first few centuries of each millennium (1000 years). The last palindromic date in the second millennium (years 1001 to 2000) in this format was August 31, 1380 or 08-31-1380.

According to Dr. Inan, in the mm-dd-yyyy format, the first Palindrome Day in the current millennium (January 1, 2001 to December 31, 3000) was October 2, 2001 (10-02-2001) and the last such day will be September 22, 2290 (09-22-2290).

There will be 12 Palindrome Days in the 21st century in the mm-dd-yyyy format. The first one was on October 2, 2001 (10-02-2001) and the last one will be on September 2, 2090 (09-02-2090).

In the dd-mm-yyyy format, there are 29 Palindrome Days in the current century. The first was 10 February, 2001 (10-02-2001). The last is a special one – it’s a leap day! 29 February, 2092 (29-02-2092) will be the last Palindrome Day of the 21st century.
