Robert Fitzpatrick does not lack conviction.
"I'm trying to warn people about what's coming," Fitzpatrick told the Daily News. "People who have an understanding [of end times] have an obligation to warn everyone."
Fitzpatrick spent his money on 1,000 placards on subway cars and several more on bus shelters around the city. They read: "Global Earthquake! The Greatest Ever - Judgment Day: May 21."
The retiree's beliefs are based on the predictions made by Harold Camping, who claims the rapture will take place on May 21. Fitzpatrick said the cataclysmic event will happen just before 6 p.m. Eastern.
Camping made a similar world-ending prediction in 1994, but he admitted he got his calculations wrong that time.
Fitzpatrick said he has no doubt that Camping's latest proclamation is correct.
