The sun and the clock in Edmonton (2026)
Edmonton lies at 113.5°W. Its time zone, UTC−6, is built around the 90°W meridian. The 23.5° gap between them means the clock runs roughly 94 minutes ahead of the sun: solar noon arrives at about 13:34 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 17h 3m of daylight. The shortest is 22 December, with 7h 28m. The swing between them is 9h 36m. This is the latitude band where the difference between summer and winter evenings is most obvious.
The earliest sunrise and the latest sunset do not land on the longest day. In Edmonton the sun comes up earliest on 18 June at 05:04, while the latest sunset waits until 26 June at 22:07. 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 Edmonton that civil twilight runs about 35 minutes at the equinox, stretching to 53 minutes at the solstice.
