Did You Know?
Tonga has long marketed itself as the place where the day begins, sitting just west of the date line at UTC+13. It is also the only Pacific island nation never formally colonised.
The clock: Tonga experimented with daylight saving to reach UTC+14 in summer, level with Kiribati's Line Islands as the earliest clock on Earth. It abandoned the practice in 2017.
Nuku'alofa lies at 175.2°W. Its time zone, UTC+13, is built around the 165°W meridian. The 10.2° gap between them means the clock runs roughly 41 minutes ahead of the sun: solar noon arrives at about 12:41 rather than 12:00. The zone holds UTC+13 all year — there is no daylight saving here.
The longest day of 2026 is 22 December, with 13h 25m of daylight. The shortest is 22 June, with 10h 51m. The swing between them is 2h 34m. Inside the tropics the day length stays within a narrow band all year.
The earliest sunrise and the latest sunset do not land on the longest day. In Nuku'alofa the sun comes up earliest on 28 November at 05:51, while the latest sunset waits until 17 January at 19:28. The equation of time is what separates them: the Earth's elliptical orbit and axial tilt move solar noon back and forth by several minutes over the year.
The sky stays usably light for a while after the sun goes down. In Nuku'alofa that civil twilight runs about 22 minutes at the equinox.
