The sun and the clock in Nouméa (2026)
Nouméa lies at 166.4°E. Its time zone, UTC+11, is built around the 165°E meridian. The 1.4° gap between them means the clock runs roughly 6 minutes behind the sun: solar noon arrives at about 11:54 rather than 12:00. The zone holds UTC+11 all year — there is no daylight saving here.
The longest day of 2026 is 22 December, with 13h 30m of daylight. The shortest is 22 June, with 10h 46m. The swing between them is 2h 44m. 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 Nouméa the sun comes up earliest on 29 November at 05:02, while the latest sunset waits until 16 January at 18:43. 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 Nouméa that civil twilight runs about 22 minutes at the equinox.
