1960: Piazzi Smyth, a past astronomer royal of Scotland, wrote a book circa 1860 titled "Our Inheritance in the Great Pyramid." It was responsible for spreading the belief in pyramidology throughout the world. This is the belief that secrets are hidden in the dimensions of the great pyramids. He concluded from his research that the millennium would start before the end of 1960 CE.
1967: During the six day war, the Israeli army captured all of Jerusalem. Many conservative Christians believed that the rapture would occur quickly. However, the final Biblical prerequisite for the second coming is that the Jews resume ritual animal sacrifices in the temple at Jerusalem. That never happened.
1970's: The late Moses David (formerly David Berg) was the founder of the Christian religious group, The Children of God. He predicted that a comet would hit the earth, probably in the mid 1970's and destroy all life in the United States. One source indicated that he believed it would happen in 1973.
1972: According to an article in the Atlantic magazine, "Herbert W. Armstrong's empire suffered a serious blow when the end failed to begin in January of 1972, as Armstrong had predicted, thus bringing hardship to many people who had given most of their assets to the church in the expectation of going to Petra, where such worldly possessions would be useless." 3
1974: Charles Meade, a pastor in Daleville, IN, predicted that the end of the world will happen during his lifetime. He was born circa 1927, so the end will probably come early in the 21st century.
1975: A major Jehovah's Witness prediction date.
1978: Chuck Smith, Pastor of Calvary Chapel in Cost Mesa, CA, predicted the rapture in 1981.
1980: Leland Jensen leader of a Baha'i World Faith group, predicted that a nuclear disaster would happen in 1980. This would be followed by two decades of conflict, ending in the establishment of God's Kingdom on earth.
1981: Arnold Murray of the Shepherd's Chapel taught an anti-Trinitarian belief about God, and Christian Identity. Back in the 1970's, he predicted that the Antichrist would appear before 1981.

1982: Pat Robertson predicted a few years previously that the world would end in the fall of 1982.
1982: Astronomers John Gribben & Setphen Plagemann predicted the "Jupiter Effect" in 1974. They wrote that when various planets were aligned on the same side of the sun, tidal forces would create solar flares, radio interruptions, rainfall and temperature disturbances and massive earthquakes. The planets did align, as seen from earth, but nothing unusual happened.
1984 to 1999: In 1983, Bhagwan Shree Rajneesh, later called Osho, teacher of what has been called the Rajneesh movement, is said to have predicted massive destruction on earth, including natural disasters and man-made catastrophes. Floods larger than any since Noah, extreme earthquakes, very destructive volcano eruptions, nuclear wars etc. will be experienced. Tokyo, New York, San Francisco, Los Angeles, Bombay will all disappear. Actually, the predictions were read by his secretary; their legitimacy is doubtful.
1985: Arnold Murray of the Shepherd's Chapel predicted that the war of Aramageddon will start on 1985-JUN 8-9 in "a valley of the Alaskan peninsula."
1986: Moses David of The Children of God faith group predicted that the Battle of Armageddon would take place in 1986. Russia would defeat Israel and the United States. A worldwide Communist dictatorship would be established. In 1993, Christ would return to earth.
1987 to 2000: Lester Sumrall, in his 1987 book "I Predict 2000 AD" predicted that Jerusalem would be the richest city on Earth, that the Common Market would rule Europe, and that there would be a nuclear war involving Russia and perhaps the U.S. Also, he prophesized that the greatest Christian revival in the history of the church would happen: all during the last 13 years of the 20th century. All of the predictions failed.
1988: Hal Lindsey had predicted in his book "The Late, Great Planet Earth" that the Rapture was coming in 1988 - one generation or 40 years after the creation of the state of Israel. This failed prophecy did not appear to damage his reputation. He continues to write books of prophecy which sell very well indeed.
Alfred Schmielewsky, a psychic whose stage name was "super-psychic A.S. Narayana," predicted in 1986 that the world's greatest natural disaster would hit Montreal in 1988. Sadly, his psychic abilities failed him on 1999-APR-11 when he answered the door of his home only to be shot dead by a gunman.
1988-MAY: A 1981 movie titled "The man who saw tomorrow" described some of Nostradamus predictions. Massive earthquakes were predicted for San Francisco and Los Angeles.
1988-OCT-11: Edgar Whisenaut, a NASA scientist, had published the book "88 Reasons why the Rapture will Occur in 1988." It sold over 4 million copies.
About 1990: Peter Ruckman concluded from his analysis of the Bible that the rapture would come within a few years of 1990.
These are all failed predictions.
Sorry it is a bit long, there have been rather a lot of them. I took it from the 1960s only, the full thing just ran on and on.
And we are still here
