"7 Years of Tribulation"
I read the article by Pastor Riley, but find myself quite confused by
one thing.  The Tribulation is seven prophetic years, 360 days in
length.  Now I'm no brain surgeon, but my calculations leave me with a
total of 2520 days for that time frame.  The extra thirty days Pastor
Riley is tacking onto the Tribulation cannot be a part of it.
This thirty days has confused many a Bible scholar throughout the
years, but I dare say that I have never heard nor read anyone's
explanation, that is backed up by scripture, which explains this
beyond an educated guess.

Me: well, at least YaThink recognizes the problems with the above post
snippet. That's headway for some at least.

YaThink, here is an explanation for the 30 days if you are interested...

Go to www.godstimeline.net and view the chart entitled "The 70th Week
& Days of Daniel"...the 70th Week contains more than 2520 days and the
30 days that you mentioned in your post are explained with scripture
only (no dreams or visions or "algorithms").
