Linda came up with some 666 calculations from the 666 calculator at
 
http://novusordoseclorum.com/
 
RAPTURE alone = 594, so I don't know how she arrived at :
 
RAPTUREDATESEPTEMBER5,2004 = 666
 
RAPTURESEPT2004 = 606

Since these were off I didn't bother checking any others, but the calculator didn't work for me anyway. I had to use a regular calculator.
