I saw this posted somewhere else and thought it was cool. Have you ever noticed that the days this week in May have the same numbers going from and to front and back. Take a look at this:
5-10-15
5-ll-l5
5-12-15
5-13-15
5-14-15
5-15-15
5-16-15
5-17-15
5-18-15
5-19-15
Found out this is called Palindrome.
