Twosday 2022: What’s so special about 10.22pm tonight?

Watch: Twosday Is A Once-In-A-Lifetime Palindrome Date

It may not be marked on the calendar, but today is ‘Twosday’, where all the numbers line up to create the date 22.2.22.

Better still, at 10.22 tonight, the time will be 22.22 on 22.2.22 - and to make it all even more perfect, ‘Twosday’ also falls on a Tuesday.

The date is a palindrome, meaning it reads the same both forwards and backwards, and an ambigram (meaning that it still reads the same if flipped upside down).

People have planned weddings to coincide with the date, and doomsday prophets have even suggested it could be a day of disaster in Ukraine.

Morten Heedegaard, 50, has maintained a website counting down to 10.22 tonight from three years.

He spoke to the Washington Post this week, saying, “It started actually as a bit of a joke. I’m kind of a numbers geek I tried to make a tweet at one point, addressing the United Nations to make that date the day of self-celebration and self-care. They didn’t respond.”

Heedegaard says that he’s not sure there’s a bigger meaning to the date.

He says: “Literally, it’s useless, because what should make that day any different from any other date, apart from the fact that humans have invented a way of counting days, and years, and months? And by coincidence, that date is going to be a date full of twos, and we originate our timing from a day and a year at which a certain guy named Jesus was born.”

A 2018 Ohio state study shone light on why people see patterns in everything - and perhaps why humans find patterns satisfying.

Participants were placed in an MRI machine and asked to predict which photo is coming next in a sequence.

"We could see what parts of the brain were activated when participants figured out that there was a pattern - or realised that there was no pattern," said Ian Krajbich, co-author of the study and assistant professor of psychology and economics at The Ohio State University.

When people picked out patterns, the ventromedial prefrontal cortex was activated - part of the brain which has been shown in other research to be associated with reward.

"One interpretation is that people may be getting a sense of reward for figuring out whether there is a pattern or not. We don't know that for sure yet, but it is plausible," Krajbich said.

"The brain is keeping track of more things than we previously thought. It isn't just about predicting what is coming next. It is looking for rules to help predict better and faster."
