The following is my account of what happened on each day of the movie Groundhog Day. There were more days implied, but these are the only days that were either shown or explicitly implied.
Groundhog Day! Tries to get back to Pittsburgh, but gets snowed out.
Gets up and sees no snow on the ground. Weirds out more and more, but holds it together. Makes no real changes from Day 1. Before going to bed, he breaks a pencil to check on the next morning.
The pencil is whole! Is totally freaked now and skips doing the groundhog report. Instead, he asks Rita to meet him at the Tip-Top Cafe to ask for her help. Goes to a neurologist and psychiatrist and ends up bowling with the morons. Realizes that he can do whatever he wants without consequence, goes on a rampage ("I'm not gonna live by their rules any more!"), plays chicken with a train, and gets tossed in jail.
Wakes up at the Bed & Breakfast and realizes he got away with going nuts the previous night. Starts to take advantage of his situation. Slugs Ned Ryerson, pigs out at Tip-Top Cafe, and gets info from Nancy Taylor to hit on her the next day.
Picks up Nancy, but keeps calling her Rita.
Has scheme to get all the money he needs (steals it from armored truck). Goes to movie with girl in French maid outfit.
Tries to find out about Rita at Tip-Top Cafe. Buys Rita a drink at the bar that evening.
Buys Rita a drink. Gets the drink right but the toast wrong.
Buys Rita a drink. Gets the drink right and the toast right. They have dinner together and he laughs at her when she tells him she majored in 19th century French poetry.
Same as previous day, but this time he recites a French poem when she tells about her major. They make a snowman and dance in park. She comes up to his room and she slaps his face.
Same as previous day, but before going to his room they build a snowman (while he goes giddy over the notion of fatherhood). She slaps his face at the end of night.
She slaps his face.
She slaps his face again, and depression sets in.
Even worse. Swills whiskey and watches Jeopardy.
Wakes and smashes clock/radio alarm
Smashes clock/radio alarm, kidnaps the woodchuck, and drives off a cliff.
Electrocutes himself with a toaster in the bathtub.
Steps in front of a truck.
Jumps off a building. Rita and Larry identify the body.
In the cafe with Rita. Says he is a god. Proves he knows everything about everyone and that he knows what's going to happen before it happens. She spends rest of day with him as an "objective witness."
The beginning of the end! Comes out of depression. Gives a wad of bills to begger. Brings coffee and danishes for Larry and Rita at groundhog taping. Starts piano lessons.
Greets the dweeb he runs into every morning outside his room with happy Italian words of hope and promise. More piano lessons. Takes up ice sculpting.
More piano lessons.
Instead of slugging Ned Ryerson, he embraces him and convinces him that he's gay. Takes the old begger to the hospital to die.
Takes the begger out for breakfast and gives him mouth-to-mouth in attempt to save his life in the evening. Begger dies. Apparently, he learned here to accept that there are some things he just can't change.
The day he got it right! Makes a great speech at the groundhog taping. Catches a boy falling out of tree. Fixes a flat tire for three elderly ladies. Administers the Hiemlich to Buster, the Groundhog Day official, in restaurant. Plays piano at groundhog party. Rita buy's him at the bachelor auction/fundraiser. Everyone comes up and thanks him for what he did for them during the day.
