The writer of the movie Groundhog Day wanted Bill’s timeloop to last an extremely long time, more than a couple lifetimes, maybe longer. The studio said no, hows about you make it like 2 weeks (how lame would *that* have been? He kills himself more than 14 times). Director Harold Ramis keeps it ambiguous, but has implied that it was more than 10 years. The only refernece to how long the movie has been happening is when Bill says it takes six months to master the card throwing trick.
