just a few excerpts from a longer article (above)

Civilizations around the world have been celebrating the start of each new year for at least four millennia. Today, most New Year’s festivities begin on December 31 (New Year’s Eve), the last day of the Gregorian calendar, and continue into the early hours of January 1 (New Year’s Day). Common traditions include attending parties, eating special New Year’s foods, making resolutions for the new year and watching fireworks displays.

As part of his reform, Caesar instituted January 1 as the first day of the year, partly to honor the month’s namesake: Janus, the Roman god of beginnings, whose two faces allowed him to look back into the past and forward into the future. Romans celebrated by offering sacrifices to Janus, exchanging gifts with one another, decorating their homes with laurel branches and attending raucous parties.

In the United States, the most iconic New Year’s tradition is the dropping of a giant ball in New York City’s Times Square at the stroke of midnight. Millions of people around the world watch the event, which has taken place almost every year since 1907. Over time, the ball itself has ballooned from a 700-pound iron-and-wood orb to a brightly patterned sphere 12 feet in diameter and weighing in at nearly 12,000 pounds. Various towns and cities across America have developed their own versions of the Times Square ritual, organizing public drops of items ranging from pickles (Dillsburg, Pennsylvania) to possums (Tallapoosa, Georgia) at midnight on New Year’s Eve.
