On average we get a Friday the 13th every 212 days.
We already had one this year in September.
We will have another one in June 2014.
Friday the 13th really ALL has to do with the Dissolution of the Knights Templar on Friday, October 13th, 1307. [See above post.]
So Friday the 13th in December is meaningless. Sorry.
