Groundhog Day ending explained

What happens

After a quiet night with Rita, Phil wakes and the day is finally February 3. Rita is beside him, and he asks to stay in Punxsutawney. The loop breaks once he has become someone worth releasing.

The last image

Phil and Rita stand together in the snow-covered town, free of the loop, with a new day beginning.

What it says

The loop is never explained, because it works as a test, not a puzzle. Phil escapes only when he stops trying to beat the day and starts caring for others. His choosing the town shows that routine can become a life worth living.
