In the Gregorian calendar, New Year’s Eve (also known as Old Year’s Day or Saint Sylvester’s Day in many countries), the last day of the year, is on 31 December. In many countries, New Year’s Eve is celebrated at evening social gatherings, where many people dance, eat, drink, and watch or light fireworks. Some Christians attend a watchnight service. The celebrations generally go on past midnight into New Year’s Day, 1 January.

Tonga and Kiritimati (Christmas Island), part of Kiribati, are examples of the first places to welcome the New Year while Baker Island in the United States of America is among the last.
