re: Why are you contradicting yourself?"
I'm not. You're asking different questions. Your first question was "Ok. So your problem is how three days and three nights can fit between Friday afternoon and Sunday?" But your next question was "you think Matthew 12:40 can only have been an idiom if Jesus died on Friday and resurrected on Sunday?" Different questions, different answers required.
