The sun and the clock in Richmond (2026)
Richmond lies at 77.4°W. Its time zone, UTC−5, is built around the 75°W meridian. The 2.4° 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. Under daylight saving the clocks move 60 minutes forward, widening the gap to 70 minutes and pushing solar noon to 13:10.
The longest day of 2026 is 22 June, with 14h 46m of daylight. The shortest is 22 December, with 9h 34m. The swing between them is 5h 11m. This is the latitude band where the difference between summer and winter evenings is most obvious.
The earliest sunrise and the latest sunset do not land on the longest day. In Richmond the sun comes up earliest on 14 June at 05:48, while the latest sunset waits until 30 June at 20:35. 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 Richmond that civil twilight runs about 26 minutes at the equinox, stretching to 31 minutes at the solstice.
