I used to try to figure out the return of the Messiah and start of the end times procession by using a 6000 year timeline.  I realized later when things did not show up on schedule that there was one incorrect assumption that I was making that was to blame: the assumption that the 6000 years began counting at Adam's creation, rather than Adam's departure from Eden.
 
See, the 6000 years represent man working in his own ways apart from God just like the six days of the biblical work week. The 1000 years following, or the Sabbath Millennium are man under God's government again, represented by the Sabbath day.
 
I say "again" because Adam and Eve were under God's government in the garden.  Those years therefore do not count towards the six millenial days of man on his own.  In other words God's 6000/7000 year plan did not start until the "Fall".
 
The question, then, is how long was Adam in the Garden before he was kicked out to decide what was right in his own eyes?  Well, I have many problems with Judaism's explanation that he was created on "Rosh Hashanah" (the counterfeit start of the year --in the Fall!--for the true Biblical holy day of Yom Teruah/Day of Trumpets) and rebelled that day and was kicked out that same day.
 
Instead, I believe Adam was created in the garden in the Spring a number of years before Satan turned bad and got jealous of God and influenced mankind to doubt and reject the instructions of God in the Fall possibly on Yom Kippur since that is the Day of the Lord when Messiah will destroy Babylon as depicted in Revelation 19 (that would make it 6000 years to the day that man was without God's government). The Book of Jubilees says something like seven years, but if that is correct I believe we have already passed the 6000 year mark a few years ago.  At this point I think Adam was in the Garden several more than seven years from Creation and the 70th week of Daniel will begin a year after a sabbath year seven years before the 6000th year from that year Adam "fell".  But I'm always open to better theories when I find one.
