Piton de la Fournaise on Réunion has erupted more than 150 times since the 17th century, several times a decade in recent years, which makes it among the most consistently active volcanoes anywhere. Eruptions are largely effusive and watched from the roadside.
The clock: Saint-Denis keeps UTC+4 — a French département three hours ahead of Paris in winter and two in summer, with the same currency, laws and school curriculum.
Saint-Denis lies at 55.5°E. Its time zone, UTC+4, is built around the 60°E meridian. The 4.5° gap between them means the clock runs roughly 18 minutes ahead of the sun: solar noon arrives at about 12:18 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 24m of daylight. The shortest is 22 June, with 10h 52m. The swing between them is 2h 32m. 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 Saint-Denis the sun comes up earliest on 28 November at 05:29, while the latest sunset waits until 17 January at 19:05. 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 Saint-Denis 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.
