Today is one of the most unusual days of your life. It's a palindrome date, no more than the second in the lives of anyone living today. Using the MM/DD/YYYY form most common in the U.S., today is 01-02-2010, which reads the same backward and forward. The first such date in our lives was Oct. 2, 2001, that is, 10-02-2001. The most recent palindrome date before that was Aug. 31, 1380 - or 08-31-1380. There will be 10 more in this century. So today, "Step on no pets."
