The Guiana Space Centre at Kourou launches European rockets from about 5° north, close enough to the equator that the Earth's rotation adds roughly 460 m/s of free velocity eastward — worth a significant payload increase.
The clock: Cayenne keeps UTC−3, four hours behind Paris in winter and five in summer, in a département that is part of the EU and uses the euro.
Cayenne lies at 52.3°W. Its time zone, UTC−3, is built around the 45°W meridian. The 7.3° gap between them means the clock runs roughly 29 minutes ahead of the sun: solar noon arrives at about 12:29 rather than 12:00. The zone holds UTC−3 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 12h 24m of daylight. The shortest is 22 December, with 11h 50m. The swing between them is 34 minutes. Within a few degrees of the equator the length of the day barely moves all year.
The earliest sunrise and the latest sunset do not land on the longest day. In Cayenne the sun comes up earliest on 23 October at 06:14, while the latest sunset waits until 20 July at 18:47. 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 Cayenne that civil twilight runs about 21 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.
