29 11 13 - a prime day29th November 2013 – 29 11 13 – What a day!

Its a prime day – all the numbers: 29 11 & 13 are prime

But also: 291113 is a prime number

And not only that, but if you write the date in the American format: month day year you get: 112913 which is also a prime number

Plus its the last prime day (when all the numbers e.g. 29 11 13 are prime numbers) until February 2017.  So enjoy it whilst you can!

Whatever you do on this Prime Day, have a great day.

    Is the writing date format different for each country?
