The sun and the clock in Punta del Este (2026)
Punta del Este lies at 54.9°W. Its time zone, UTC−3, is built around the 45°W meridian. The 9.9° gap between them means the clock runs roughly 40 minutes ahead of the sun: solar noon arrives at about 12:40 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 14h 30m of daylight. The shortest is 22 June, with 9h 48m. The swing between them is 4h 42m. At this latitude the seasons are visible in the clock, but never dramatic.
The earliest sunrise and the latest sunset do not land on the longest day. In Punta del Este the sun comes up earliest on 7 December at 05:19, while the latest sunset waits until 7 January at 19:57. 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 del Este that civil twilight runs about 25 minutes at the equinox, stretching to 30 minutes at the solstice.
