angel eyes, I posted this for you in another thread last night, but apparently you didn't get to see it. This is an example of what the WTS published on 1975:
"WHAT about all this talk concerning the year 1975? Lively discussions, some based on speculation, have burst into flame during recent months among serious students of the Bible. Their interest has been kindled by the belief that 1975 will mark the end of 6,000 years of human history since Adam's creation. The nearness of such an important date indeed fires the imagination and presents unlimited possibilities for discussion.
2 But wait! How do we know their calculations are correct? What basis is there for saying Adam was created nearly 5,993 years ago? Does the one Book that can be implicitly trusted for its truthful historical accuracy, namely, the Inspired Word of Jehovah, the Holy Bible, give support and credence to such a conclusion?
35 One thing is absolutely certain, Bible chronology reinforced with fulfilled Bible prophecy shows that six thousand years of man's existence will soon be up, yes, within this generation! (Matt. 24:34) This is, therefore, no time to be indifferent and complacent. This is not the time to be toying with the words of Jesus that "concerning that day and hour nobody knows, neither the angels of the heavens nor the Son, but only the Father." (Matt. 24:36) To the contrary, it is a time when one should be keenly aware that the end of this system of things is rapidly coming to its violent end. Make no mistake, it is sufficient that the Father himself knows both the "day and hour"!
36 Even if one cannot see beyond 1975, is this any reason to be less active? The apostles could not see even this far; they knew nothing about 1975. All they could see was a short time ahead in which to finish the work assigned to them."

Or perhaps you like to hear the words directly from Fred Franz' mouth:

To blame the R&F witnesses for "reading too much into 1975" is offensive.
