The Palindrome: Why 02-02-2020 Is A Unique Date

The date — February 2, 2020, or 02/02/2020 — is a palindrome, meaning it reads the same forwards as it does backward.

The eight-digit date is especially rare because it works in every part of the world, where dates are written as day-month-year, or as month-day-year.

This is the only time the special sequence will occur this century, reports the Washington Post.

The last time such a palindrome occurred was 909 years ago on 11/11/1111. It won’t happen again for another 101 years, when the calendar turns to 12/12/2121.
