Maybe symmetry is inherently pleasing. Perhaps it is the whiff of cosmic clout. Or it could be that in our divided times, uniting over something as indisputable as the date is just the divertissement we crave.
Why a Day Like Sunday Hasn't Been Seen in 900 Years
Whatever the case, Sunday's super-rare date of 02-02-2020, the only eight-digit global palindrome of the century, has people talking, with #PalindromeDay trending on Twitter.
Palindrome derives from the Greek word for running back again, and defines a number, word or phrase that is the same read forward and backward. (Think: "Madam, in Eden, I'm Adam.")
Aziz Inan is professor of electrical engineering at the University of Portland and a palindrome aficionado. Tracing back and looking ahead over centuries, he mines palindromes like gems and says the last time we had an eight-digit palindrome date was 908 years ago on 11-11-1111.
"I tell my students they are lucky to have such a date in their lifetime," Inan tells The Oregonian.
While the U.S. was marking the palindrome of 11-02-2011, in the U.K., it was 02-11-2011, or just another Wednesday.
But on Sunday, the Brits got in on the fun. The math department at the Solihull School in the U.K. calculated some palindromic bonuses; Sunday also happens to fall on the 33rd day of the year, with 333 days remaining in the year. (2020 is a leap year and with the added day in February has 366 days.)
Ivanka Trump points out to her 7.6 million Twitter followers that most of us won't be around on the the next eight-digit palindrome date of 12-12-2121.
After that, it will be 908-year wait until the next one on 03-03-3030.
Other palindromes using fewer digits, like 8-10-18, are more commonplace.
Some couples view palindromes as dates to seize the day and take the plunge.
Little Vegas Chapel tweeted Sunday, "Today marks the first specialty date of the month! Congratulations to all the wonderful couples getting married on this day of 2/2/20!"
But in China, where officials are trying to get ahead of the fast-spreading coronavirus outbreak, the date saw a surge of couples registering to wed, spurring the government to advise couples to postpone their weddings.
The civil affairs administration said the registration process involves an official portrait, requiring people to remove their masks, a move deemed too risky in the outbreak that's infected more than 14,000 people and killed more than 300.
"Where marriage registrations have been announced or promised for February 2 this year, you are advised to cancel it and explain the situation to others," the notice said, according to VOA.
The ministry also asked for funerals to be held in a "simple and expeditious manner to avoid gatherings of people."
