Did You Know?
The Salar de Uyuni covers about 10,580 square kilometres and varies in elevation by less than a metre across its whole extent, which makes it the flattest surface on the planet. Satellites use it to calibrate their altimeters.
The clock: Uyuni keeps UTC−4 at 3,656 metres. When a thin layer of water sits on the salt, the surface becomes a mirror visible from space.
Uyuni lies at 66.8°W. Its time zone, UTC−4, is built around the 60°W meridian. The 6.8° gap between them means the clock runs roughly 27 minutes ahead of the sun: solar noon arrives at about 12:27 rather than 12:00. The zone holds UTC−4 all year — there is no daylight saving here.
The longest day of 2026 is 22 December, with 13h 22m of daylight. The shortest is 22 June, with 10h 53m. The swing between them is 2h 29m. Inside the tropics the day length stays within a narrow band all year.
The earliest sunrise and the latest sunset do not land on the longest day. In Uyuni the sun comes up earliest on 27 November at 05:38, while the latest sunset waits until 17 January at 19:13. 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 Uyuni that civil twilight runs about 22 minutes at the equinox.
Every figure in this section is computed from the city's own latitude, longitude and IANA time zone using NOAA solar algorithms (Spencer, 1971), accurate to about ±2 arcminutes below 65° latitude.
