17713

Wednesday 17^th July 2013 – another prime day!

17713 is prime as are all the individual components: 17, 7, 13

And it works in America too!

Writing the month, day, year still yields a prime number 71713

It’s the last UK Prime Day until November (America get another prime day on 23 July – 72313)

(note: I’m publishing this blog post on Tuesday 16th July so you find out about it before the day itself!)
