For those of you who haven't been paying attention, it could be your last day here on Earth.
At 6 p.m. Saturday, according to radio host Harold Camping, the Day of Rapture and the start of Judgment Day begins.
At this writing there have been no reports of people being taken up into heaven, but plenty of folks are talking about it.
Jim Brenneman, a cartoonist and CNN iReporter in Marcellus, New York, said he expects to remain on Earth, but you never know.
"Although I assume that I've lived a sinful life and will probably be here on Sunday, there is a small chance that maybe I was better than I thought and might get sucked up into the heavens on Saturday with all the other self-righteous wing nuts," he said. "If that happens, feel free to have my stuff. But probably not! Let the Looting Begin! HAPPY APOCALYPSE EVERYONE!!"
Brenneman posted a cartoon envisioning himself being caught up.
Another iReporter, Greg Reese, created an entertaining - and thought-provoking - video from interviews with people on the streets of Cincinnati.
The top Twitter trend on Saturday morning was #endoftheworldconfessions. Among them:
Lord_Valdemort7: "I 'let the dogs out.' It was me."
Firenzeii: "You know your cute little bunny rabbit? The one you called Fluffy and loved more than anything else? I ate him."
BiebersNachos: "I loved, I love and I will always love this sexy badass singer called Justin Drew Bieber :)"
WagTheFox: "You really do look fat in those jeans. There. I said it."
CNN iReporter Jutka T. Emoke Barabas from Honolulu just isn't that into the Rapture.
"We have better things to do, like take care of our environment," the iReporter said. "Today we should reflect about what we could do that our planet would be a better and more livable place for everyone in the future and not think about the end of our planet."
She said she drew a picture of Earth covered with different trees because she was tired of hearing about all this "doomsday business." While still on the Earth, Barabas suggested, "just plant a tree."
She said she plans to do just that on Sunday for the people affected by the March 11 earthquake and tsunami in Japan.
CNN iReporter Cameron Harrelson, 16, from southern Georgia, started researching the idea of Saturday as Judgment Day after his literature teacher had students express their thoughts on the day in their class journals.
"The Bible tells us no man, not even Jesus, knows the day he will return," Harrelson said, and so those predicting the day are trying to elevate themselves to the status of God.
"I am ready if it happens tonight a 6 o'clock, but I don't think it is very likely," he said.
