Wednesday, 5/20/15, has two cool operations going for it. The day, month, and year are multiples of five. And since 5 – 20 = -15, it is a minus subtract day.
But, the big news is the newly found palindromes! We noted last week that 5/15/15, or 51515, is the same forward and backward. It turns out that all the dates from 5/11/15 to 5/19/15 are palindromes! So today, tomorrow, and Tuesday are all special: 51715, 51815, and 51915.
