I happened to notice that you have done a substantial revision to a couple of your sites. I have downloaded them. Is there anything in particular you would direct my attention to?
By the way, speaking of 12’s and 7’s, it is interesting to note that the current Hebrew calendar cycle of 19 months equals 12 + 7. Also , the 120 years (or especially the jubilees of years, as you mentioned) which God gave to mankind prior to His judgment with the flood, would comprise the whole span of time of the biblical record from Adam to the approximate close of this century and millenium.
