Have a thing for symmetry? Every date this week is palindromic.

If you forgot your junior high school math, a palindrome is a word or phrase that can be read the same forward and backward. "Race fast safe car," is a famous example. "Madam, I'm Adam" is another one, as is "Never odd or even."

Depending how you write it, dates can be palindromic. Take, for example, the 10th of September, this year: 9-10-19.

Tomorrow, too, will be a palindromic date: 9-11-19, as will the 9-12-19 and every date through the 19th: 9-19-19.

It's rare, but not that rare, and of course how you write the date matters. According to the University of Portland, there are 38 palindromic dates per century, if you use the full year in your date format.
