The sun and the clock in Praia (2026)
Praia lies at 23.5°W. Its time zone, UTC−1, is built around the 15°W meridian. The 8.5° gap between them means the clock runs roughly 34 minutes ahead of the sun: solar noon arrives at about 12:34 rather than 12:00. The zone holds UTC−1 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 13h 1m of daylight. The shortest is 22 December, with 11h 14m. The swing between them is 1h 46m. 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 Praia the sun comes up earliest on 3 June at 06:03, while the latest sunset waits until 10 July at 19:08. 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 Praia that civil twilight runs about 21 minutes at the equinox.
