President-elect Joe Biden's inauguration will be numerically historic. It will be the first to happen on the date of a palindrome and won't be repeated for 1,000 years.
A palindrome a word, verse, or sentence or a number that reads the same backward or forward, according to Merriam-Webster.
The date is Jan. 20, 2021 -- 1/20/2021. Take out the slashes and it's 1202021. It can also be a five-digit palindrome: 1/20/21
The next time this happens will be in the year 3021.
Also, every day this week will be part of a five-digit palindrome: 1/20/21, 1/21/21 and so on.
This, of course, assumes that one does not put a zero ahead of the first "1."
The Farmer's Almanac says 2021 will have 22 palindrome dates and that there are only two years in a century in which this can happen. Those are the ones ending in 11 and 21.
The other palindrome dates this year were the four-digit 1-2-21 and the five-digit palindromes from 12-1-21 to 12-9-21, plus 12-11-21 and 12-22-21.
Dec. 2 will mark the only date that can also be an eight-digit palindrome this year: 12-02-2021.
