In New York City, thousands of people gather in Times Square to watch a crystal ball drop at midnight. Even if you aren't in the Big Apple, millions of Americans tune into the event on their televisions.
This is crystal ball!
This is Times Square when the clock strikes midnight. The streets are packed and fireworks surround the square.
After midnight, Americans sing the song Auld Lang Syne, which is an old Scottish song that has become an integral part of American culture.
On New Year's Eve, most families attend parties with other family members and friends. They are out until very early in the morning!
