The sun and the clock in Banff (2026)
Banff lies at 115.6°W. Its time zone, UTC−6, is built around the 90°W meridian. The 25.6° gap between them means the clock runs roughly 102 minutes ahead of the sun: solar noon arrives at about 13:42 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 16h 35m of daylight. The shortest is 22 December, with 7h 53m. The swing between them is 8h 42m. 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 Banff the sun comes up earliest on 18 June at 05:26, while the latest sunset waits until 26 June at 22:02. 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 Banff that civil twilight runs about 33 minutes at the equinox, stretching to 47 minutes at the solstice.
