"But Of That Day and Hour Knoweth No Man..."

Except these people:

If there had been time, Marie Exley would have liked to start a family. Instead, the 32-year-old Army veteran has less than six months left, which she’ll spend spreading a stark warning: Judgment Day is almost here.

Exley is part of a movement of Christians loosely organized by radio broadcasts and websites, independent of churches and convinced by their reading of the Bible that the end of the world will begin on May 21, 2011.

To get the word out, they’re using billboards and bus stop benches, traveling caravans of RVs and volunteers passing out pamphlets on street corners. Cities from Bridgeport, Conn., to Little Rock, Ark., now have billboards with the ominous message, and mission groups are traveling in countries from Latin America to Africa to spread the news outside the U.S.

“A lot of people might think, ‘The end’s coming, let’s go party,’” said Exley, a veteran of two deployments in Iraq. “But we’re commanded by God to warn people. I wish I could just be like everybody else, but it’s so much better to know that when the end comes, you’ll be safe.”

I've heard predictions like this since the late 60's. Matthew 24:36 seems to be pretty clear that NO man knows the hour, so I'm doubting that the guy promoting May 21st has the goods.
