St. John's lies at 61.9°W. Its time zone, UTC−4, is built around the 60°W meridian. The 1.9° gap between them means the clock runs roughly 7 minutes ahead of the sun: solar noon arrives at about 12:07 rather than 12:00. The zone holds UTC−4 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 13h 9m of daylight. The shortest is 22 December, with 11h 6m. The swing between them is 2h 3m. 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 St. John's the sun comes up earliest on 5 June at 05:32, while the latest sunset waits until 8 July at 18:45. 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 St. John's that civil twilight runs about 22 minutes at the equinox.
