I know that 6 6 6 means something bad but is 12 12 12 bad?

Because my father's birthday is on December 12th 1948 which in 2012 would make it 12/12/12 which ironically enough is also the same date his driver's license expires and 2012 is also the year the world will supposedly come to an end. I mean they all seem to coincide with each other so do you think that means anything?
