Apocalypse

Interesting that people are preparing for the end of the world as we know it in the year 2012. People all over the world are gearing up for the end of civilization in that year. Many of these people are believers in the Bible, I'm sure. That being the case, what about the Scripture that says no man knows the day or the hour. Why would God say that and then tell the Mayans that the year 2012 is THE YEAR? Just wondering!!!
