The sun and the clock in Juneau (2026)
Juneau lies at 134.4°W. Its time zone, UTC−9, is built around the 135°W meridian. The two very nearly coincide: solar noon — the moment the sun is highest — falls at about 11:58, which is as close to true solar time as a zone this wide can get. Under daylight saving the clocks move 60 minutes forward, widening the gap to 58 minutes and pushing solar noon to 12:58.
The longest day of 2026 is 22 June, with 18h 17m of daylight. The shortest is 22 December, with 6h 23m. The swing between them is 11h 54m. Close to the Arctic or Antarctic circle, the year swings hard between long light and long dark.
The earliest sunrise and the latest sunset do not land on the longest day. In Juneau the sun comes up earliest on 19 June at 03:50, while the latest sunset waits until 25 June at 22:08. 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 Juneau that civil twilight runs about 39 minutes at the equinox, stretching to 79 minutes at the solstice.
