The Watch Tower Society is not known for its accuracy. Here is their claim:
5 From Bible chronology, Jehovah’s witnesses as far back as 1877 pointed to the year 1914 as one of great significance. The Watchtower as of March 1880 said: “‘The Times of the Gentiles’ extend to 1914, and the heavenly kingdom [of God] will not have full sway till then.” While they were not yet clear on just what the details would be, in the nearly four decades preceding 1914 they sounded the warning that the future for this present system would not be one of peace, security and prosperity for mankind, but that in 1914 the world would come to the greatest time of trouble ever. In 1897 the book The Battle of Armageddon, (at first entitled “The Day of Vengeance”) published by Jehovah’s witnesses, said that this trouble would be “more general and widespread, and more destructive, as the machinery of modern warfare signally suggests. Instead of being confined to one nation or province, its sweep will be over the whole world, especially the civilized world, Christendom.”
6 The momentous year of 1914 came, and with it World War I, the most widespread upheaval in history up to that time. It brought unprecedented slaughter, famine, pestilence and overthrow of governments. The world did not expect such horrible events as took place. But Jehovah’s witnesses did expect such things, and others acknowledged that they did. On August 30, 1914, the New York World said: “The terrific war outbreak in Europe has fulfilled an extraordinary prophecy. For a quarter of a century past, through preachers and through press, the ‘International Bible Students’ . . . have been proclaiming to the world that the Day of Wrath prophesied in the Bible would dawn in 1914.‘Look out for 1914!’ has been the cry of the . . . evangelists.”
7 How could Jehovah’s witnesses have known so far in advance what world leaders themselves did not know? Only by God’s holy spirit making such prophetic truths known to them. True, some today claim that those events were not that hard to predict, since mankind has long known various troubles. But if those events were not hard to predict, then why were not all the politicians, religious leaders and economic experts doing so? Why were they telling the people the opposite? And why did they persecute Jehovah’s witnesses for telling things that were later seen to be the truth? ( The Watchtower 01. August1971 p.468 )
Here is what the Society actually printed regarding 1914 in their publication The Time is at Hand (1889):
How refreshing the prospect brought to view at the close of these seven times! Neither Israel nor the world of mankind represented by that people will longer be trodden down, oppressed and misruled by beastly Gentile powers. The Kingdom of God and his Christ will then be established in the earth, and Israel and all the world will be blessed under his rightful and righteous authority. […] 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; but we are living in a special and peculiar time, the "Day of Jehovah," in which matters culminate quickly; and it is written, "A short work will the Lord make upon the earth." (See Vol. I, chap. xv.) 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 near the end of A.D. 1914. (p. 98f)
The final extinction of this counterfeit hierarchy, near the close of the "Day of wrath" and judgment already begun--which will close, as shown by the "Times of the Gentiles,"with the year A.D. 1914. (p.356)
