Is judement day really on May 21st, 2011?

Well, I was talking to my Grandma and she told me about familyradio(actually name of radio station/company) and how the head of it Harold Camping says the rapture(when God takes the righteous on with him) is going to happen on May 21st, 2011. I was so scared and I don't know if its true or not. Of course it means everlasting life with GOd, but there's so much more I wanted to do on Earth. Plus, the bible says no man knows the time nor date, but Camping created a biblical timeline and it seems accurate. Do you think its true.
