Well, this guy does take a while > to get to the point (( like they all do :))
but basically someone noticed that there are four events in Daniel 9
such as the Cross, 70AD, Wars and Desolations ... and that four times
Daniel's 490 years is 1600 years.
((if these really go together))  So, yes, 1600 Years of desolation
after 70AD is, you guessed it, 2030  
  So anyway, his a bit confusing site is at

I had to go through it three times to figure it out so you don't have to
