The sun and the clock in Hanga Roa (2026)
Hanga Roa lies at 109.4°W. Its time zone, UTC−6, is built around the 90°W meridian. The 19.4° gap between them means the clock runs roughly 78 minutes ahead of the sun: solar noon arrives at about 13:18 rather than 12:00. Under daylight saving the clocks move 60 minutes forward, widening the gap to 138 minutes and pushing solar noon to 14:18.
The longest day of 2026 is 22 December, with 13h 51m of daylight. The shortest is 22 June, with 10h 26m. The swing between them is 3h 26m. At this latitude the seasons are visible in the clock, but never dramatic.
The earliest sunrise and the latest sunset do not land on the longest day. In Hanga Roa the sun comes up earliest on 2 December at 07:16, while the latest sunset waits until 12 January at 21:17. 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 Hanga Roa that civil twilight runs about 23 minutes at the equinox.
