Citing Aziz Inan of the University of Portland, Oregon, the almanac said 2021 will be an especially good year for palindrome dates, with a total of 22. The first was a four-digit palindrome on Jan. 2, or 1-2-21. Nineteen are five-digit palindromes, which occur in January and December.
In January, the dates are 1-20-21 through 1-29-21, while in December there will be nine dates from 12-1-21 through 12-9-21.
The final two dates are Dec. 11 (12-11-21) and Dec. 22 (12-22-21).
Inan said that only two years in a century contain 22 palindrome dates, which are years ending in 11 and ending in 21.
