It is the first “dating” verse in Revelation. So it could be the start of the seventieth week or something significant like Psalm 83 or Ezk 38. There is a total solar eclipse that literally slashes across the US in August 2017 and then completes the X in 2024. So I am not sure exactly what it signifies, but it is something “Biblical” ;-)
So, an attack on Israel?
That total solar eclipse is followed 4 minutes later by the new moon. Rosh Chodesh immediately follows.
