Don't worry, lol. It is something put out by FamilyRadio.com (which I know nothing about, BTW) but it is some sort of ploy to get people to listen to their message or something. The Bible tells us NO ONE knows the time or day of the Second Coming of Christ.
I think they think they have some sort of formula to do the calculations to get this date. Uh, no. lol Oh, I see they are saying it is 7,000 years since God destroyed the world with flood (Noah), lol. Okey-dokey, then.
I'd plan on paying the house payment that month.

But, one could plan a party for the night before if one would like.
Oh my! I just went to their website and looked at their homepage. I stay away from doom and gloom like this, while I believe there will be a Second Coming someday, I do not pretend to know when or believe anyone (or website) can tell us when either. I think this site is forgetting the Bible says "He will come as a thief in the night." No one knows when a thief is showing up, they don't usually call and tell you.
