Jake - Like I said in my answer to Didgery, only God knows the actual date of the end of the world.
Anyone who says the world will end on such a date in such a year is a fool. And the web link you gave certainly shows the foolishness of those who thought they knew better than the Bible.
As a Bible believing Christian I don't claim to know WHEN the earth will end, just that it WILL end, in the manner described in the Bible.
Now whether that's in ten years or a hundred years, who knows.
(I'm sure those of an atheistic mind set believe that one day the world will end too, whether by the sun going supernova or some other cosmic calamity)
You said : <If somebody told you something was just about to happen 60 times on the trot and it didn't would you still believe them? >
Well here is something that has happened. 100% of everybody on this earth before us have died. Henry VIII, Churchill, whoever, they have all died, as will you and I some day.
"It is appointed unto men once to die, and then the judgment".
What's important is how we face God. Either with our own unrepented sins and gultiness, or trusting in the merits and blood of the Lord Jesus Christ.
"For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord" Romans 6:23
That's why the Bible exhorts us to hurry ,('behold, today is the day of salvation'), for we don't know when our own last day will be.
