On May 21, "starting in the Pacific Rim at around the 6 p.m. local time hour, in each time zone, there will be a great earthquake, such as has never been in the history of the Earth," he says. The true Christian believers — he hopes he's one of them — will be "raptured": They'll fly upward to heaven. And for the rest?
"It's just the horror of horror stories," he says, "and on top of all that, there's no more salvation at that point. And then the Bible says it will be 153 days later that the entire universe and planet Earth will be destroyed forever."
Most Bible scholars note that even Jesus said he had no idea when Judgment Day would come. But May 21 believers like Haubert are unfazed.
"I've crunched the numbers, and it's going to happen," he says.
Haubert says the Bible contains coded "proofs" that reveal the timing. For example, he says, from the time of Noah's flood to May 21, 2011, is exactly 7,000 years. Revelations like this have changed his life.
"I no longer think about 401(k)s and retirement," he says. "I'm not stressed about losing my job, which a lot of other people are in this economy. I'm just a lot less stressed, and in a way I'm more carefree."
Camping's predictions have inspired other groups to rally behind the May 21 date. People have quit their jobs and left their families to get the message out.
"Knowing the date of the end of the world changes all your future plans," says 27-year-old Adrienne Martinez.
She thought she'd go to medical school, until she began tuning in to Family Radio. She and her husband, Joel, lived and worked in New York City. But a year ago, they decided they wanted to spend their remaining time on Earth with their infant daughter.
"My mentality was, why are we going to work for more money? It just seemed kind of greedy to me. And unnecessary," she says.
And so, her husband adds, "God just made it possible — he opened doors. He allowed us to quit our jobs, and we just moved, and here we are."
Now they are in Orlando, in a rented house, passing out tracts and reading the Bible. Their daughter is 2 years old, and their second child is due in June. Joel says they're spending the last of their savings. They don't see a need for one more dollar.
"You know, you think about retirement and stuff like that," he says. "What's the point of having some money just sitting there?"
"We budgeted everything so that, on May 21, we won't have anything left," Adrienne adds.
So he's not planning for May 22?
"Absolutely not," Camping says. "It is going to happen, There is no Plan B."
I've asked a dozen of Camping's followers the same question. Everyone said even entertaining the possibility that May 21 would come and go without event is an offense to God. They all hope they'll be raptured. Some worry about being left behind.
"If I'm here on May 22, and I wake up, I'm going to be in hell," says Brown. "And that's where I don't want to be. So there is going to be a May 22, and we don't want to be here."
