Now that's interesting digderidoo, so they do set themselves up as prophets? Do they provide evidence then or at least stories of prophetic visions? What they are? How they experience them etc?
Janey they made their prophecies through readin the book of Daniel and Revelations, they applied these to Matthew and Lukes account of the last days, and confirmed it with measurements of Egypt's great pyramid. They also applied a few single scriptures to rhese books and came up with dates, it wasn't a case of having a prophetic vision, it was through study of the bible and applying it to calculations and measurements of the Greta Pyramid in Egypt.
Here are a few examples of their prophecies,
1874 "Prophecy can not be understood until it has been fulfilled or is in the course of fulfillment. From 1874 to 1914 the prophecy concerning the Lord's coming was being fulfilled and could be understood, and was understood, by those who were faithful to the Lord and who were watching the development of events, but not by others." {CREA 290}
1874 "Applying the same rule then, of a day for a year, 1335 days after 539 A.D. brings us to 1874 A.D. at which time, according to Biblical chronology, the Lord's second presence was due." {CREA 298} [the day for a year basis is a technique used in Astrology known as Progressions]
1874 "The Scriptural proof is that the second presence of the Lord Jesus Christ began in 1874 A.D." {PROP 65}
1914 "The prophecy of the Bible, fully supported by the physical facts in fulfilment thereof, shows that the second coming of Christ dates from the fall of the year 1914." {WHAT} [written in 1932: see next quotation] 1914 "In the year 1943 the Watch Tower Bible and Tract Society published the book 'The Truth Shall Make You Free.' In its chapter 11, entitled 'The Count of the Time,' it did away with the insertion of 100 years into the period of the Judges and went according to the oldest and most authentic reading of Acts 13:20, and accepted the spell-out numbers of the Hebrew Scriptures. This moved forward the end of six thousand years of man's existence into the decade of the 1970's. Naturally this did away with the year 1874 C.E. as the date of return of the Lord Jesus Christ and the beginning of his invisible presence or parousia." {GKTY 209} [Claim that 'parousia' change from 1874 to 1914 came only in 1943, not in 1932 in WHAT, when the WTBTS completed a new chronological system, which included moving Jerusalem's destruction from 606 B.C. to 607 B.C.E. to keep the 1914 date while finally accounting for the non-existing zero year. Also see HIS2 133] 1914 "True, it is expecting great things to claim, as we do, that within the coming twenty-six years all present governments will be overthrown and dissolved.. In view of this strong bible evidence concerning the Times of the Gentiles, we consider it an established truth that the final end of the kingdoms of this world, and the full establishment of the Kingdom of God, will be accomplished at the end of A.D. 1914 .." {TIAH 1908 ed 98-9} 1914-8 ".. the years 1914 and 1918 are specially marked dates with reference to his coming." {CREA 289/310} 1915 "we consider it an established truth, that the final end of the kingdoms of this world, and the full establishment of the kingdom of God will be accomplished by A.D. 1915. At that time the prayer of the church, ever since her Lord took his departure, - 'Thy kingdom come' - will be answered; and under its wise and just administration, the whole earth will be filled with the glory of the Lord" {TIAH 1915 ed 99} [Original contains '1914' instead of '1915'] 1918 "The parallel, therefore, would establish definitely that the harvest would close forty years thereafter; to wit, in the spring of A.D. 1918. If this is true, and the evidence is very conclusive that it is true, then we have only a few months in which to labor before the great night settles down when no man can work." {WR Oct 1 1917 6149} 1918 "We have no doubt whatever in regard to the chronology relating to the dates of .. 1918, .. It was on this line of reckoning that the dates .. 1918 were located; and the Lord has placed the stamp of his seal upon .. 1918 beyond any possibility of erasure. What further evidence do we need?" {WT May 15 1922 150} 1924-5 "After 1925 expect shortly Abel, Enoch, Noah, Abraham, Isaac, Jacob.. No doubt many boys and girls who read this book will live to see Abraham, Isaac, Jacob, Joseph, Daniel, and those other men of old come forth in the glory of their better resurrection, of perfect in mind and body. It will not take long for Christ to appoint them to their post of honor and authority as his earthly representatives. The world and all the present conveniences will seen strange to them at first, but they will soon become accustomed to the new methods. They may have some amusing experiences at first; for they never saw telephones, radios, automobiles, electric lights, aeroplanes, steam engines, and many other things so familiar to us." {TWTP 224-6} 1925 "The great Pyramid of Egypt, standing as a silent and manimate witness of the Lord, is a messenger; and its testimony speaks with great eloquence concerning the devine plan (Isaiah 19:19).. Arius .. Waldo .. John Wycliffe .. Martin Luther [were all] part of God's Organization." {WT May 15 1925 148-9} Hope it helps in whatever you are looking for. Paul
