Did You Know?
Mauritius is surrounded by a nearly continuous coral reef, which is why its lagoons are calm enough to swim in almost anywhere. The island rose from a volcanic hotspot about 8 million years ago and has no continental shelf.
The clock: Grand Baie keeps UTC+4. Mauritius has the highest population density of any African country.
Grand Baie lies at 57.6°E. Its time zone, UTC+4, is built around the 60°E meridian. The 2.4° gap between them means the clock runs roughly 10 minutes ahead of the sun: solar noon arrives at about 12:10 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 20m of daylight. The shortest is 22 June, with 10h 55m. The swing between them is 2h 25m. 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 Grand Baie the sun comes up earliest on 27 November at 05:22, while the latest sunset waits until 18 January at 18:55. 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 Grand Baie that civil twilight runs about 22 minutes at the equinox.
