Palindrome Dates

I didn’t have time to post about it yesterday, but yesterday’s date was a palindrome! (For those of you who don’t know, a palindrome is something that reads the same backward as it does forward- Yesterday’s date was 01022010.) It was only the second palindrome date of the 21st century. The first was 10022001 (October 2, 2001), and before that the last palindrome date was August 31, 1380! (Note: I am talking about palindromes of the form MMDDYYYY or YYYYMMDD. Both of these forms, when reversed on the dates listed below, read the same.)

Though palindrome dates are pretty rare, there will be 12 in the 21st century. When there is a new millennia, it turns out there are usually 12 palindrome dates each century–one for each month–for the first two centuries. The exception to this was in the 1300s, which only had 7 and was the third century of that millennium.

Anyway, while I was waiting for my food at a restaurant last night, I took a moment and figured out the 12 palindrome dates of this century. Two have already passed, so 10 remain.
Here are the ones for the 21st century:

10/02/2001
01/02/2010
11/02/2011
02/02/2020

04/02/2040
05/02/2050
