Friday, February 12, 2021, is a palindrome day -- in some parts of the world -- since the date in 12/02/2021 format reads the same forwards and backwards. And this special day hasn't escaped the attention of Twitter users, giving rise to the #palindromeday hashtag.
Because words and numbers are fascinating for so many people, Friday, 12 February 2021 is a truly poetic kind of day. Embodying a type of word play known as a "palindrome," the date 12/02/2021 has a satisfying symmetry, whether read from left to right or from right to left.
But with different countries using different date formats, palindrome days aren't the same in all global regions. In fact, February 12, 2021, isn't a palindrome in the US, for example, where the date is usually written month/day/year.
In this respect, the last universal palindrome fell on February 2, 2020 (02/02/2020), transcending the international variation. And it appears to be the only one this century.
In the day/month/year format, there are 29 palindrome days in the 21st century, according to Aziz Inan, professor of electrical engineering at the University of Portland, with the final one being February 29, 2092.
On Twitter, the #palindromeday hashtag has been riding high on the social network and users have been coming up with all kinds of grammatical gags and other homages in celebration.
