Kiritimati (Christmas Island) in the Line Islands is the world's largest atoll. Based on a 1995 realignment of the International Date Line, the Line Islands were the first area to enter into a new year, including year 2000. For that reason, Caroline Island was renamed Millennium Island in 1997. The majority of Kiribati, including the capital, is not first, for example New Zealand (UTC+13 in January) has an earlier new year.
