SoCal,
From other sources, I am expecting a major destructive event (probably in New York City) as early as October 23, followed by a widespread destructive event worldwide on or near October 24.
On the far end, I am expecting that these destructive events will have taken place no later than November 15.
So, short answer, four weeks.
Blessings to you and your loved ones,
Dan :-)
Thank you.
