My primary concern went as follows:
The bible is wrapped in 7's and 12's. The 12's tend to, like a clock or like the zodiac ecliptic metphorically wraps the earth, have one in the center - whether that was 12 tribes of Jacob around Yahweh in the Pentateuch or 12 apostles around Jesus. Sevens are considered in days of the week, in the defunct cosmology/astronomy of Mercury thru Saturn with the moon and sun also as planets, and perhaps pertaining to that you had 12 (really 13 with Yahweh) defeat the 7 tribes of Canaan. You also have people like Michael Heisler speaking of a Divine Counsel, ie. seven Elohim, which also fits pretty close to many other creation narratives of that time (the Jewish menorah seems to hold true to that formation as well with three to either side and one central).
The Bembine Tablet as analyzed by Eliphas Levi has 12 on top, 12 below, and seven in the middle where they have Isis in the center of the seven. The Bembine/Isiac tablet is of unknown origin, best guessed to be the work of some Hermetic group in late Renaissance Italy. So with the Bembine - 12, 7, 12.
If you follow that so far consider 13's and 33's in occult value. 33 = 13 + 13 + 7.
Is there a 13/13/7? Nope. Is there a 13/7/13? Well yeah, if you're in the UK, we call it 7/13/13 here in the US - either way today fell under that math.
I'm generally not a believer in numerology, but, I am a believer in human stupidity. I also don't think that Hermeticists, Kabbalists, etc. are as a group people who are likely to jump at the chance to do something negatively crazy on a day like that. What did get edified though when I just started playing with the numbers around January or so was a concern over what 3/13/2013 might have had in store - that got overly edified, not only by supposed 'Petrus Romanus' getting elected but getting called out at 20:13 in the Vatican's particular timezone.
One really good guess getting nailed on the mark might have concerned me a bit more that I should have taken it. Regardless that was the logic.
Another fun one, which I doubt will have anything but you never know - 1/13/14 might be a great day for Isis to find the missing 14th piece of Osiris (ie. the part that would be most valuable to her).
Really after this, unless you count 2033, there won't be anything this blunt in terms of 7's, 13's, and 33's. It does make it an interesting year to see whose trying to map their decisions to numerology and who isn't.
What concerned me the most though were that some people were predicting absolute economic collapse (ie. the Japan domino into Europe, US, and Aus/NZ economies) to come in July - ie. massive orchetrated bank holidays as the global Ponzi scheme finally gave up the ghost. If that were true today would have been the perfect occultic point to drop that kind of gem (or turd) and if not that find some other major way to invoke martial law.
Like I said though - I couldn't be happier that they're wrong and that my concern to that end was wrong.
