The thing is, we don't know "which" Fall !  > We also "know" or
at least suspect that Jesus will return to fulfill the Fall feasts be
here for the feast of Tabernacles at the end of the Tribulation.  We
also know that Revelation says the seven year Tribulation period will
be shortened, otherwise no life will be saved.
    Now the latest info seems to be that Rosh Hashona will be this
October 2nd- 4th.  Some are insisting it is a week earlier, which was
yesterday Sept 24th. I just looked out the window, & I'm still here!
> Unless the last trump is tomorrow, Thursday at the end of the
feast.
   Anyway, with all that said, I noticed some years ago that a few
days before Tabernacles is 45 days after the ninth of Av, and that
these two days may be  somehow connected by the 1290 and 1335 days of
Daniel ch 12.
