## Prime Number Days in 2013

August 6th, 2013 by Math Tricks | No Comments | Filed in Prime Numbers

2013 is a great year for prime numbers.  I have been periodically checking days in 2013 to see if they were prime, and then noting it on the Facebook page if they were.  I have been kicking myself because I have not come up with the idea of determining all of the prime number days in 2013 until now!  Ah well, better late then never – presenting . . .

## The BIG List of Prime Number Days in 2013

Did you know that New Year’s Eve 2013 is a prime number day?

Did you also know that there are several consecutive prime number days in 2013?

Here is a list that i generated of all the prime number days in 2013.  The format I searched is MMDDYY.  It is left to you as an exercise to find the prime number days in other standard formats – lol!
