For the rest of this week, you can read from left to right or right to left, or even upside down — and every day will look the same.
That's because the dates written out in numerical order are palindromes. In other words: They are identical backwards and forwards.
Wednesday, for instance, is 5/13/15 — forward and backward.
So how often does this occur, not for a single day, but for an entire week?
Next year: from 6/11/16 through 6/19/16.
And there's this: The last palindrome for a single day on the U.S. calendar was 11/02/2011. It was one of only eight in the 21st century.
