Regarding your theme of 70 years, I saw the following quote at the Rita website.  

"Just thought it was worth noting that 70  Biblical years (70 x 360 = 25,200 days) from Israel’s traditionally recognized Declaration of Independence (5/14/48) is 
complete as of this coming Friday, May 12, 2017."

Calculation from time and date website:
>From Friday, May 14, 1948
Added 25,200 days

Result: Friday, May 12, 2017

Interesting 70 year anniversary with all the speculation about possible Pentecost rapture timing.
