Sunday is shaping up to be a unique day for reasons other than the Super Bowl and Groundhog Day: It's also a rare palindrome.

While various forms of palindrome dates are fairly common, 02/02/2020 has the unique distinction of reading the same backward and forward when written out in eight digits in multiple date systems, according to University of Portland professor Aziz Inan.

“We are so lucky to have such a special palindrome date occurring in our lifetime because it’s so rare,” Inan told USA TODAY Saturday.

For starters, it's an eight-digit palindrome: 02022020. Many palindrome dates are only symmetrical if you write the date with seven digits (1-10-2011) — or in some cases even fewer (9-10-19).
