Napoleon was exiled to Saint Helena in 1815 and died there in 1821, on an island about 1,900 km from the nearest mainland. Jacob's Ladder, a staircase of 699 steps, climbs straight out of Jamestown up the valley wall.
The clock: Jamestown keeps UTC+0. The island's first airport was completed in 2016, but wind shear kept large jets away; scheduled flights began in 2017 with smaller aircraft.
Jamestown lies at 5.7°W. Its time zone, UTC+0, is built around the prime meridian (0°). The 5.7° gap between them means the clock runs roughly 23 minutes ahead of the sun: solar noon arrives at about 12:23 rather than 12:00. The zone holds UTC+0 all year — there is no daylight saving here.
The longest day of 2026 is 22 December, with 13h 4m of daylight. The shortest is 22 June, with 11h 11m. The swing between them is 1h 54m. 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 Jamestown the sun comes up earliest on 23 November at 05:42, while the latest sunset waits until 21 January at 19:01. 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 Jamestown 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.
