Tomorrow’s date will be written as an eight-digit palindrome around the world, the first time this has happened in 900 years.

The coincidence is rare because countries use differing conventions. February 2, 2020, is a palindrome whether expressed as day/month/year (02/02/2020), month/day/year (02/02/2020), or year/month/day (2020/02/02).

This happened last on November 11, 1111, and it won’t happen again until March 3, 3030.

02/01/2020 UPDATE: A number of readers have pointed out that 12/12/2121 works fine too, and it’s barely more than a century away.
