The clock: Avarua keeps UTC−10, the same as Hawaii, though it sits south of the equator and on the other side of the date line from New Zealand, which it is in free association with.
Avarua lies at 159.8°W. Its time zone, UTC−10, is built around the 150°W meridian. The 9.8° gap between them means the clock runs roughly 39 minutes ahead of the sun: solar noon arrives at about 12:39 rather than 12:00. The zone holds UTC−10 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 50m. The swing between them is 2h 35m. 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 Avarua the sun comes up earliest on 28 November at 05:49, while the latest sunset waits until 16 January at 19:26. 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 Avarua that civil twilight runs about 22 minutes at the equinox.
