Have the Jehovah's Witnesses predicted the end of the world?

Question

I have heard somewhere that at various times in the past, the Jehovah's Witnesses (Watchtower Bible & Tract Society) have predicted when the end of the world would be and perhaps when Jesus would return to earth.

What are the specifics about these prophecies, and when exactly is the end of the world or Christ's return supposed to occur?

Answer 1

I believe they have for 1914 & 1925, but I may be missing some years.

Adding some info from the below source per request;

1899 "...the 'battle of the great day of God Almighty' (Revelation 16:14), which will end in A.D. 1914 with the complete overthrow of earth's present rulership, is already commenced," (The Time Is at Hand, 1908 edition, p. 101).

1918 "Therefore we may confidently expect that 1925 will mark the return of Abraham, Isaac, Jacob and the faithful prophets of old, particularly those named by the Apostle in Hebrews 11, to the condition of human perfection," (Millions Now Living Will Never Die, p. 89).

1922 "The date 1925 is even more distinctly indicated by the Scriptures than 1914," (Watchtower, Sept. 1, 1922, p. 262).

1923 "Our thought is, that 1925 is definitely settled by the Scriptures. As to Noah, the Christian now has much more upon which to base his faith than Noah had upon which to base his faith in a coming deluge," (Watchtower, Apr. 1, 1923, p. 106).

Below indicate the claim to be prophets;

"So does Jehovah have a prophet to help them, to warn them of dangers and to declare things to come? These questions can be answered in the affirmative. Who is this prophet?...This "prophet" was not one man, but was a body of men and women. It was the small group of footstep followers of Jesus Christ, known at that time as International Bible Students. Today they are known as Jehovah's Christian Witnesses...Of course, it is easy to say that this group acts as a 'prophet' of God. It is another thing to prove it," (Watchtower, Apr. 1, 1972, p. 197). (See Deut. 18:21.)

Jehovah's Witnesses & Incorrect End Dates

Now that we have left December 21, 2012 behind us...the topic remains intriguing. Have Jehovah's Witnesses given incorrect dates for the end? The answer is given in the Watchtower issue of January 1, 2013.

George D. Chryssides of Birmingham University, has written a helpful, scholarly journal arguing against the much of the rhetoric spewed by Ex-Witness and 'Christian' critics.

"I aim to show that, although there have been some unrealized expectations, changes in Watch Tower chronology are attributable more to changed chronological schemes, rather than to failed predictions. --- Contrary to popular belief, the Watch Tower Society has not repeatedly set dates for the world's end, found its expectations disappointed, rescheduled the eschatological timetable, and repeated this sequence each time expectations have been frustrated."
