Didn't the world already end in 1992?
According to the cult behind the famed door-knocking bunch the world ended (or more accurately the war of armageddon started) in 1914, 1915, 1918, 1920, 1925, 1941, 1975 and 1994... (and others, if you can believe they were still at it after all that!)
It's amazing we're still around to talk about these things!
The Baha'i leader predicted a nuclear disaster in 1980... Now though I was born in 1980 and when I was a kid my parents did describe my room as a "bomb site" a number of times... rumours he'd confused my birth with a nuclear holocaust can not be confirmed.
The world seems to have ended, on average, once every 19 years and roughly 6 months (and that's ignoring several witness predictions too).
The average would probably be even shorter if we included interpretations on Nostradamus too, but since he was writing about the past and not the future I don't think it's right to include him. He
did (if I recall correctly) subscribe to the view that history repeats itself so writing about the past would mean writing about the future too, but since he was demonstrably writing about the past I don't count it as a prediction, which is a much harder science* - especially when you have to actually face the year of your prediction, and your public again after.
* I use the word in the loosest possible (and furthest from the true) sense.
