Saint Lucia has produced two Nobel laureates — Arthur Lewis in economics and Derek Walcott in literature — from a population of under 180,000, usually cited as the most laureates per capita of any sovereign state.
The clock: Castries keeps UTC−4. The Pitons, two volcanic spires rising about 770 metres straight from the sea, are a UNESCO site.
Castries lies at 61.0°W. Its time zone, UTC−4, is built around the 60°W meridian. The two very nearly coincide: solar noon — the moment the sun is highest — falls at about 12:04, which is as close to true solar time as a zone this wide can get. The zone holds UTC−4 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 12h 57m of daylight. The shortest is 22 December, with 11h 18m. The swing between them is 1h 39m. 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 Castries the sun comes up earliest on 3 June at 05:35, while the latest sunset waits until 11 July at 18:36. 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 Castries that civil twilight runs about 21 minutes at the equinox.
