COEUR D'ALENE, Idaho -

A California man predicting Saturday will be the end of the world is spreading his controversial message across the country including right here in the Inland Northwest.

Harold Camping is a retired civil engineer and runs of one of the largest Christian radio networks in the world, Family Radio. Camping said he came up with May 21st as Judgment Day based off a series of calculations using biblical numbers.

Camping also predicted the world was coming to an end in 1994.

On Thursday, three of Camping's followers were in Coeur d'Alene holding signs warning and preparing people for the end of the world.

"I just know it's going to happen Saturday," said Paul Ivanov, as he stood on the corner of Appleway and Highway 95. "I know we have a day and a half left."

Ivanov said he expected the doomsday message would be met with mixed emotions.

"A lot of people back in Jesus' day didn't accept Jesus when he was preaching you know. A lot of people wanted to stone him and eventually crucify him," he said.

Two men challenged Ivanov's beliefs by asking him to sign over the title to his car since he won't need it after the weekend.

"It's not going to matter my friend, it's not going to matter. The day's going to be here in less than a day and a half," Ivanov said to the men.

"I don' t think you believe it," one man responded

Josh Crawford noticed the signs when he stopped at a nearby gas station to get snacks for a road trip.

"To be quite honest I think it's kinda looney to pinpoint a Judgment Day on one certain day it's almost like it came out of nowhere," said Crawford.

Shawn Chapin stopped to invite Ivanov and his friends his local church.

"I believe if you read the bible it's pretty clear no man knows the time or the date and anyone who sets that date is really setting them up for failure," said Chapin.

Ivanov believes the Rapture will begin at 3 p.m. Pacific Time on Saturday.

"I don't have any plans. I definitely will be reading the bible and praying to God but that's as far as I've thought," said Ivanov.

Crawford won't be marking the date or time on his calendar.

"No way, no way," said Crawford. "I think this world's got plenty more years its been around a few billion I think we have a few more million to go at least."
