I can throw another thought in to add to the plethora of dates.

Apart from the June 25 idea based on 1930, I had been considering the 155 low to low giving July 10 or 14.

But part of that 155 is the typical 56 days down. SPX 25/08/1987 - 20/10/1987 being the prime example.

So using SPX here, you have 56 cal days from top giving 20/06/2010.

Sierra has spiral date for Jun 19, and others have similar plus solstice around that period etc.

It turns out both Jun 19 and 20 are weekend so leaves 18 or 21.
