The sun and the clock in Yellowknife (2026)
Yellowknife lies at 114.4°W. Its time zone, UTC−6, is built around the 90°W meridian. The 24.4° gap between them means the clock runs roughly 97 minutes ahead of the sun: solar noon arrives at about 13:37 rather than 12:00. The zone holds UTC−6 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 20h of daylight. The shortest is 22 December, with 4h 58m. The swing between them is 15h 2m. 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 Yellowknife the sun comes up earliest on 20 June at 03:39, while the latest sunset waits until 24 June at 23:39. 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 Yellowknife that civil twilight runs about 45 minutes at the equinox, stretching to 68 minutes at the solstice.
