Hi Robert,
 
Well, I think most people like to use the June 7, 1967 date b/c it takes us to Sept. 23, 2015 Feast Atonement/Yom Kippur when we factor in the 7 weeks (49yrs/17640 day) of Daniel 9, and b/c of that I think it stands out. It does not seem that any other significant date such as this brings us to Atonement of any year other that 6/7/67. However, the info. in your post gives us a starting point of June 28, 1967. I was thinking about this earlier and thought...echoing Matt M's post, there really was no tangeble, concrete announcement by Israel or anyone for that matter to restore and build Jerusalem on 6/7/67...that we can discern. Although some prophecy experts highlight this date as the starting point for the 7 weeks countdown. The statement you have is from Menachim Begin and says June 28, 1967...which is 21 days after the fact. So I got to thinking, what if the command to restore and build Jerusalem came from the Throne Room of God Himself?? I think its worth mentioning, the initial prophecy came from the Father, went to the angel Gabriel, and was given to Daniel. It only says, "that from the command to restore and build Jerusalem, until Messiah the Prince"...it doesn't say by who, although we assume a political leader.
 
I put myself in the shoes of Israel at that time. They were fighting off a surprise attack from all of their neighbors. The only thing (I think) that was in their minds, and the minds of the troops was to defend the homeland. I suggest that capturing Jerusalem was not priority number 1. But as it turns out, the opposition was also coming out of Jerusalem via the Jordanian side. And so as the troops advanced to fight that battle, the next thing they knew...the enemy had retreated and all Jerusalem was theirs...they stopped and looked at themselves and said, "How did this just happen"? But it happened b/c the Father gave the command. 21 days later Menachim Begin wrote to the President of Israel, "that Jerusalem is one city indivisible, the capital of the state of Israel". And so Jerusalem was restored and rebuilt...even during troublesome times, such that today it is a thriving metropolis of approx. 800,000 people. This is my speculation, and just a thought, but seems to make sense.
 
And so then 7 weeks/ 49 yrs/ 17640 day from that date, we arrive at September 23, 2015 which is the Feast of Atonement/Yom Kippur.
 
Hopefully not to long...Take it easy...
