Samoa changed its time zone in 2011 and skipped December 30 before reaching New Year's Eve.
At the end of December 29, 2011, Samoa moved across the International Date Line by changing from a side of the date line aligned with the Americas to one aligned with Australia and New Zealand. The change meant that the next calendar date after December 29 was December 31. December 30 did not occur in Samoa that year.
The government said the move would better match the country's major trading partners and regional neighbors. Before the change, business communication with Australia and New Zealand often involved a date difference of nearly a full day. Afterward, Samoa shared the same working week more closely with those markets.
The change is sometimes confused with a simple midnight celebration or with Kiribati's earlier date-line adjustments. It was a legal time-zone change, not an alteration to the length of a day. Samoa also observed daylight-saving changes during that period, making historical time comparisons require care.
