The sun and the clock in Stanley (2026)
Stanley lies at 57.9°W. Its time zone, UTC−3, is built around the 45°W meridian. The 12.9° gap between them means the clock runs roughly 51 minutes ahead of the sun: solar noon arrives at about 12:51 rather than 12:00. The zone holds UTC−3 all year — there is no daylight saving here.
The longest day of 2026 is 22 December, with 16h 40m of daylight. The shortest is 22 June, with 7h 47m. The swing between them is 8h 53m. 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 Stanley the sun comes up earliest on 14 December at 04:28, while the latest sunset waits until 30 December at 21:12. 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 Stanley that civil twilight runs about 33 minutes at the equinox, stretching to 48 minutes at the solstice.
