Port Louis lies at 57.5°E. Its time zone, UTC+4, is built around the 60°E meridian. The 2.5° 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 21m of daylight. The shortest is 22 June, with 10h 54m. The swing between them is 2h 27m. 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 Port Louis the sun comes up earliest on 27 November at 05:22, while the latest sunset waits until 17 January at 18:55.
