A hopeful guess/rumor is being discussed and analyzed .....
based on President Trump statement.

Tip of the hat to WhipLash347

Hypothesis.

A . First of all, remember this important part of the premise is that the Julian Calendar is basically 13 days behind our Gregorian calendar (adjusting the date from Trump's statement).
So the adjustment leads you to September 19.
And since it said we are “2 days ahead of schedule”, it lesds to the actual date of Friday the 17th.

B. Initial statement ......what Trump said yesterday "Pray for 21 days".
The 21st day would be October 2nd.
Drop 2173 has a link about a presidential alert on October 3rd.
Drop 2320 is on October 3rd. 2018.
Shows a wireless alert and says " What a day".
