remember that half past human was a tool designed to read stock markets.
The crash started before the 7th, it was obvious by the 7th that it wasn't going to bounce back as it had previously done.
That may have been the time when the general public started to wake up to the stock market crashing.
I personaly do not go into date predictions myself, but I do understand that people always want to know what the future brings, a little like sneaking a peak at what you are getting for Christmas rather than waiting for the day
