It is sequential day: Happy 11/12/13!

 
Rachel Blundy11 December 2013

Today is 'Noughts and Crosses day' - the last day this century which has a date containing three consecutive numbers or 'three in a row'.

Mathematician Ron Gordon, who has made a career out of tracking numerically interesting dates, is inviting people to mark the event, which is also known as 'Sequential Day'.

Enthusiasts who send him a poem or story which celebrates the date could win a share of $1112.13, according to a post on his website.

A Facebook page has even been set up for people to share their thoughts and experiences.

Mr Gordon has previously highlighted 'Square Root day' on 3/3/09 and 'Odd day' on 9/11/13.

The Californian claims it will be 89 years until the next 'Noughts and Crosses day' on 1/2/03.

On his website, he wrote: "Undeniably, it’s a winning date! Take a close look - no numbers on the calendar can be more consecutive than these three who stand so close, one next to the other.

"Such a sequence will not happen again this century. Clearly, it’s not a day to quarrel - let’s celebrate!

"These days are like calendar comets - you wait and wait and wait for them, then they brighten up your day, and poof - they're gone!".
