Samoa celebrates New Year's Eve with a major fireworks display at Apia Harbour.
Apia is Samoa's capital and sits on the north coast of Upolu, one of the country's principal islands. Public New Year celebrations there commonly center on the waterfront, where fireworks and community events mark the arrival of January 1.
Samoa is especially notable in discussions of New Year time zones because it moved west of the International Date Line in 2011. The change skipped December 30 that year and aligned Samoa more closely with trading partners in Australia and New Zealand. It also changed the order in which Samoa experiences dates relative to nearby American Samoa.
The date-line change does not mean Samoa permanently owns the world's first midnight; that depends on definitions, territories, and the exact time-zone comparison. The question identifies a specific public celebration in Apia, rather than asking for a disputed “first” claim.
