Which 1989 film follows a New Year's Eve countdown in New York as its central romantic climax?

When Harry Met Sally... uses a New Year's Eve countdown in New York as its central romantic climax.

The 1989 romantic comedy was directed by Rob Reiner and written by Nora Ephron. It follows Harry Burns and Sally Albright over many years as friendship, arguments, and changing relationships complicate their feelings for each other.

Near the end, Harry runs through New York on New Year's Eve and reaches Sally's party shortly before midnight. His declaration of love, followed by the countdown and a kiss, makes the holiday a decisive narrative setting rather than a passing backdrop.

The film is also famous for its diner scene at Katz's Delicatessen, including Sally's staged demonstration of an orgasm. That scene and the New Year's Eve ending are often discussed together, but they occur at very different points in the story. The ellipsis in the title is part of the film's official title.
