The sun and the clock in Punta Arenas (2026)
Punta Arenas lies at 70.9°W. Its time zone, UTC−3, is built around the 45°W meridian. The 25.9° gap between them means the clock runs roughly 104 minutes ahead of the sun: solar noon arrives at about 13:44 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 58m of daylight. The shortest is 22 June, with 7h 32m. The swing between them is 9h 26m. 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 Punta Arenas the sun comes up earliest on 15 December at 05:12, while the latest sunset waits until 30 December at 22:13. 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 Punta Arenas that civil twilight runs about 35 minutes at the equinox, stretching to 52 minutes at the solstice.
