There is no day called 2012. Thats a year. There are 366 days in 2012, it being a leap year. Any particular day? I'll skip breakfast if I'm going do die.
Even if there is some random planet about to come back and cause havoc we have no control over it. If it does look like its actualy going to happen closer to the time Ill make sure that I stock up on food and booze and at least have a good time!
