The Date of London 2012 Olympic & The Date of Previous Civilization Catastrophe Connection

From the book of The Orion Prophecy By Patrick Geryl, on page 85, The author state that the previous civilization (the Atlantean) was wiped out on 27th July 9792 BC. This was due to earth pole shift. Now we know that the London 2012 Olympic will be held also on a very similar date which is on 27th July 2012. Why the elite choose this date? Also notice if we calculate the numerology of the Olympic date, that is 7+2+7+2+0+1+2 the total sum is 21! Bingo we got The Operation Black Jack! Now it seems more plausible that The Operation Black Jack will be carried out by the elite on this date than any other date people assume previously. just my 2 cent anyway..
