I came across this website, the Rapture Index, a while ago. Every day, it attempts to estimate the likelihood that the rapture (the event in which Christians are taken into heaven and non-Christians are left behind) will occur that day. The author assigns numerical values to 45 factors (examples: Inflation, Anti-Semitism, Volcanoes, Satanism), adds up the numbers, and comes up with the "Rapture Index." It's at 156 today, very high--anything above 145 means "Fasten your seat belts," because we're speeding toward the occurrence of pre-tribulation rapture.
Each day, the author comments on the factors that are in flux. Some of the explanations make sense--the "Flood" factor is up because of Hurricane Katrina. Others are less obvious: the "Antichrist" factor is down lately because of "The French no vote on the EU constitution."
If you like, you can also check out the Rapture Ready FAQ, guaranteed to offend everyone I know. One of the questions: "Is the Pope the Antichrist?" Answer: probably not, because he's not Jewish. Lovely.
