• Larry Wilson of Wake Up America Seminars predicted the Second Coming "around 1998". The Tribulation was supposed to start in 1994 or 1995, and during this period an asteroid was to hit the Earth. (Robbins p.220)
• Centro, a religious cult in the Philippines, predicted that the end of the world would come in 1998. (Source: Ontario Consultants on Religious Tolerance)
• The year of the Rapture, claimed Donald B. Orsden in his book The Holy Bible - The Final Testament: What is the Significance of 666?. "Take your super computers, you scientists, and feed the number 666 into them. The output will be the proof God gives that 1998 is the year Jesus will take the faithful with him...." (McIver #2986)
• In Ominous Portents of the Parousia of Christ, by Henry R. Hall, the author pours vitriol on atheists and liberals while praising Reagan as a "wise man" sent by God for the End Times. An obvious loony, Hall predicts that the world will end in 1998 because, among other reasons, 666 + 666 + 666 = 1998. The Rapture was to take place in 1991. Sorry, Hank! (McIver #2488)

• Author Marilyn J. Agee used convoluted Biblical calculations to predict the date of two separate Raptures. In her book The End of the Age, she boldly proclaimed, "I expect Rapture I on Pentecost [May 31] in 1998 and Rapture II on the Feast of Trumpets [September 13] in 2007." (Agee) Her homepage is worth a visit just to see how...how can I put this politely?...interesting these doomsday prophets can be. She just may have another doomsday prediction posted.
• The Rapture, as per Tom Stewart's book 1998: Year of the Apocalypse. (McIver #3226)

In the following quatrain, Nosty made a grim-sounding prediction (Source: The Mask of Nostradamus by James Randi):

L'an mil neuf cens nonante neuf sept mois
Du ciel viendra un grand Roy deffraieur
Resusciter le grand Roy d'Angolmois
Avant apres Mars regner par bon heur.

The year 1999, seven months,
From the sky will come a great King of Terror:
To bring back to life the great King of the Mongols,
Before and after Mars to reign by good luck. (Quatrain X.72)

But it was not to be. When July passed, the inevitable date postponement began. The folks on the alt.prophecies.nostradamus newsgroup and the webmasters of various Nostradamus fan sites extended the deadline of fulfillment to August 13 (the end of July according to the Julian calendar used in Nostradamus' day), then September 30 ("sept mois" must have meant "September" after all!), then October 10 (the end of the 7th month of the Hebrew calendar), and finally October 22 (the end of the seventh month of the Zodiac). I expect the extending to continue well into next year! There were some who claimed that the prophecy referred a meteor that exploded over New Zealand in early July or perhaps the total eclipse of August 11. But did these events resuscitate the King of the Mongols?

• The end of the world, as foreseen by Charles Criswell King (aka The Amazing Criswell) in his 1968 bestseller Criswell Predicts: From Now to the Year 2000. As he wrote:
  
  "The world as we know it will cease to exist...on August 18, 1999.... And if you and I meet each other on the street that fateful day...and we chat about what we will do on the morrow, we will open our mouths to speak and no words will come out, for we have no future."
  
  Why August 18? I'm not certain, but it does happen to be Criswell's birthday. (Abanes p.43)
  
  
• Many alarmists were convinced that the Cassini space probe would crash into the Earth on August 18. Some even went so far as to say it would poison a third of the world's population with its plutonium, fulfilling the prophecy of Revelation 8:11 concerning a star named Wormwood -- supposedly a metaphor for radiation poisoning ("Chernobylnik" is the Russian for a purple-stemmed subspecies of the wormwood plant). But as expected, Cassini passed by the Earth without a hitch.

• The End, according to Jack Van Impe. (Shaw p.131)
• According to Escape666, Nostradamus's "King of Terror" was to descend on Earth in September, heralding the beginning of the Tribulation and the Rapture. Escape666 said, regarding Nostradamus's infamous quatrain X.72: "now we know EXACTLY when he meant: SEPTEMBER 1999." However, as the end of September approached, they changed their date to October 12. See The Doomsday List for a record of this prediction.

• Bonnie Gaunt used the Bible Codes to prove that Rosh Hashanah 5760 (September 11, 1999) is the date of the Rapture. Not surprisingly, her web page promptly disappeared on Sep. 12. However there is still a newspaper article available online about her prediction.
• Jason Hommel spammed Usenet with claims that the Rapture was to take place on this date, and used a plethora of over-imaginitive numerology and unorthodox scriptural interpretation to arrive at this conclusion. He used the famous "know not the day nor the hour" verse to paradoxically pinpoint the date of the Rapture. But in a bit of honesty rare among doomsayers, Hommel actually admitted he was wrong and apologized.
• Michael Rood also jumped on the Rosh Hashanah bandwagon. He claimed that this day is the first day of the Hebrew calendar year 6001. In reality, it's the first day of 5760, but Michael claimed that there was a mistake in the calendar. 

• Author Stefan Paulus combines Nostradamus, the Bible and astrology to arrive at September 23 as the date that a doomsday comet will impact the Earth. (Paulus p.57)
• A Nostradamus aficionado named SmaKYadowN picked September 23 as a possible date of impact of an asteroid. His website has disappeared, unfortunately, so see The Doomsday List instead.

• Apparently, there are still some active members of the Korean Hyoo-go (see Oct 28, 1992) movement left. These Tami Sect proponents predict the demise of this earth in October 1999. (Source: Korea Times)
• Jack Van Impe, one of the more crazed and entertaining end-times screechers, predicted the Rapture and the Second Coming for October 1999. (Wojcik p.212)
