The Watchtower of December 15, 2003 pages 14-19 tries to make its readers believe, without saying it clearly, that the end might come in 2034. Noah's time of the end lasted 120 years before the deluge. We are already 90 years into our time of the end that started in 1914. So, the readers would easily calculate that 1914+120 years = 2034.
Quotes :
"In Noah’s day, Jehovah declared: “My spirit shall not act toward man indefinitely in that he is also flesh. Accordingly his days shall amount to a hundred and twenty years.” (Genesis 6:3) The issuance of this divine decree in 2490 B.C.E. marked the beginning of the end for that ungodly world. Just think what that meant for those then living! Only 120 years more and Jehovah would bring “the deluge of waters upon the earth to bring to ruin all flesh in which the force of life is active from under the heavens.”-Genesis 6:17. (...) What about us? Some 90 years have passed since the last days of this system of things began in 1914."-Watchtower December 15, 2003 pages 14-19.
