From the most reliable investigations of Bible chronology, (...) we find that Adam was created in the autumn of the year 4026 B.C.E. Sometime in that same year Eve could well have been created, directly after which God's rest day commenced. In what year, then, would the first 6,000 years of man's existence and also the first 6,000 years of God's rest day come to an end? The year 1975. (Awake! October 8, 1966, p. 19)

No wait, er... 1874:
"Here we furnish the evidence that from the creation of Adam to (but not including) A.D. 1873 was six thousand years. (Studies in the Scriptures, Vol. 2, p. 39. 1889)
Yes, DEFINITELY 1874.

"According to this trustworthy Bible chronology six thousand years from man's creation will end in 1975, and the seventh period of a thousand years of human history will begin in the fall of 1975 C.E Six thousand years of man's existence on earth will soon be up, yea within this generation. The rein of Christ...to run parallel with the 7th millennium ..." (Life Everlasting in Freedom of the Sons of God, 1966, p. 29-30)
