The sun and the clock in Port-au-Prince (2026)
Port-au-Prince lies at 72.3°W. Its time zone, UTC−5, is built around the 75°W meridian. The 2.7° gap between them means the clock runs roughly 11 minutes behind the sun: solar noon arrives at about 11:49 rather than 12:00. Under daylight saving the clocks move 60 minutes forward, widening the gap to 49 minutes and pushing solar noon to 12:49.
The longest day of 2026 is 22 June, with 13h 15m of daylight. The shortest is 22 December, with 11h 1m. The swing between them is 2h 14m. 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-au-Prince the sun comes up earliest on 1 November at 05:49, while the latest sunset waits until 8 July at 19:30. 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 Port-au-Prince that civil twilight runs about 22 minutes at the equinox.
