Neat fact

Tomorrow night won’t happen again until 2049 I believe, a Friday the 13th on a full moon. At the very least, look up and remember.

Apparently you are correct! http://www.vox.com/2014/6/12/5801196/tomorrow-is-friday-the-13th-and-a-full-moon-that-wont-happen-again

so what kind of workings are best to be performed on this day?

The energy is very strong so what ever is done it will boost all workings.
I was wondering if anyone other than myself noticed the surge of energy on this night I am a security guard (in shopping market )and man the whackjobs I had to deal with and there was a unusual thing with cash registers many of them were adding up to triple digits the most common was 666 the customers laughed nervously but I loved it, though 777 came up but I was also seeing license plates in the parking lot with 0666 at least two different cars with these numbers anyways I thought all this AWESOME! and wonder who else had any thing like this?.
