John and Doves,
I may be too elementary here but:
>From Passover to Succot (April 17 to October 5) is 178 days.  The half way point from each side is July 8th.  89 days forward from Passover and 89 days back from Succot.  Pentecost is said to be the festival that sheds light on the 3 spring festivals and the 3 fall festivals (middle light of the Minorah).  July 8th is a Wednesday.  July 7th is a full moon.  July 11th is thought to possibly be the antichrist revealing (See Steve Flynn's great research).  If the church is to be removed before the revealing of the AC, then July 7th or 8th could possibly be the rapture.  

God Bless,
Bjr
(Sorry if someone has already pointed this out)
