What is the name of the New Year's Eve celebration held in Times Square that features the annual ball drop?

The New Year's Eve in Times Square celebration features the annual Times Square Ball drop.

The event takes place in the heart of Manhattan and is organized around the descent of the illuminated ball during the final minute of December 31. Its modern format includes live entertainment, a midnight countdown, confetti, and performances broadcast to viewers around the world. The ball itself is lowered from One Times Square.

The tradition began in 1907, when a lighted ball was used to signal the new year after fireworks displays had been restricted. The event is sometimes casually called “the ball drop,” but that phrase describes the central feature rather than the full celebration. It is also different from New York City's separate public events, such as the Macy's Thanksgiving Day Parade, which takes place in November and has no connection to the New Year's countdown.
