OK guys .. I love this information and I once used a force to get 13 (On a radio show), but I can't for the life of me remember it. I did it remotely and I was not on the show.... Any help remembering the source ??? Not fishing ... just AGING!!!!

I could not agree for Europe. See Feb 13 2082 and March 13 2082.

Friday, February 13 2082 - full moon

I don't know what you may have used before, but here are some ideas:

1) Do any bit where their math boils down to 9 via the digital root process, then have them add 4 as the last step.

2) Check out Phil Goldstein's Redivider, especially "Never Odd or Even AKA I Prefer Pi".

I do have that book and I've never used it once ... THANKS!!!! I thought that I had something different but for the life of me I can't find it. I think it was a radio show but I don't have hours to go through them all ... Oh well.. Thanks again!
