Many thanks for the thought provoking article:

Lot's and lot's of good number differences to think about.
 
You mention May 16, 2007, (Ascension Day):
 
Note that the 40 year generation that will not pass away, starting on Jerusalem Unification Day in 1967, that so much has been written about and anticipated, will finally be complete on the Jewish calendar, to the day on May 16, 2007.
 
June 7, 1967 = Iyar 28, 5727
 
May 16, 2007 = Iyar 28, 5767 (Jerusalem Unification Day)
 
I realize the next two analogies are old hat for many of us who have been watching and waiting all these years.
 
This first parallels the generation that would not pass away, fortold by Jesus, which Josephus had said was 40 years to 70 AD, from the crucifixion.  This is not the best analogy in that it would not be to the day, exactly 40 years.  In other words, Jesus was crucified according to the backcalculated Hebrew calendar and uttered His prophecy on Palm Sunday, which would have been in 30 AD, Sunday, March 31st, Gregorian, April 2, Julian, and Nisan 11, 3790.  The temple was destroyed around Av 9, 70 AD, although it can be argured that the stones of the temple were not dismantled till after the stones had cooled after the fire.  But  taking from Nisan 11, 30 AD to Nisan 11, 70 AD would have been 40 years.  And from Nisan 11 to Av 9 of 70 AD would have been an additional 116 days.  So adding 116 days to May 16, 2007 is September 9, 2007 which would be the earliest date, not accounting for the cooling of the stones.  Which lines up so well with Rosh Hashana, September 13, 2007, the 14th year anniversary of Oslo.
 
A better parallel, to the date, would be the 40 years in the Wilderness for that generation to pass away, which is said to have started and ended on the same Jewish date, Av 9.
 
(Note that only those older than 20 years were considered adults and those younger than 20 did not pass away, hence we could still say we have a 60 year generation with Israel's birth in 1948.)
 
Note the counting of the seven weeks from Passover to Shavoat.  A similar counting of seven weeks lands us on July 4, 2007, (May 16, 2007 + 49 = July 4, 2007.)
 
Also note that a counting of 231 days from November 18, 2006, (Cheshvan 27, the anniversary of the Lord commanding Noah to step out of the Ark), brings us to July 4, 2007.
 
I liked your Sept 23, 2006 + 234 (inclusive) = May 14, 2007.  Consider also that non-inclusive we have May 15, 2007 which straddles May 14, 2007 (Anniversary of Israel's rebirth on the Gregorian calendar), and May 16, 2007.
 
May 23, 2007 sure popped out as being an interesting date in your analysis also.  Sivan 6, (Shavout), plus connections to Oslo.  The only thing else I noticed is it is exactly 100 calendar months from this date till Yom Kippur, September 23, 2015.  Which 9/23/2015 is exactly seven weeks of prophetic years, (in possible fulfillment of the 63rd to 69th week of Daniel's 70 week prophecy), from Jerusalem Unification Day.  (June 7, 1967 + 49 * 360 = September 23, 2015.)  A lot to digest.
 
Thanks!
