Twosday
Portmanteau and one-time observance / From Wikipedia, the free encyclopedia
Twosday is the name given to Tuesday, February 22, 2022, and an unofficial one-time secular observance held on that day, characterized as a fad.[1][2] The name is a portmanteau of two and Tuesday, deriving from the fact that the digits of the date form a numeral palindrome marked by exclusivity or prevalence of the digit 2—when written in different numerical date formats, such as: 22/02/2022,[lower-alpha 1] 22/2/22 and 2/22/22.[lower-alpha 2][lower-alpha 3][4][5] It is also an ambigram.[6][lower-alpha 4] According to University of Portland professor Aziz Inan, the palindrome is one of the "ubiquitous palindromes", as it retains its defining characteristics globally, despite the differences in national date formats.[7] In countries that apply the ISO 8601 international standard for the calendar, there is an additional congruence inasmuch as Tuesday is the second day of the week under this scheme.[8]
