The sun and the clock in Cincinnati (2026)
Cincinnati lies at 84.5°W. Its time zone, UTC−5, is built around the 75°W meridian. The 9.5° gap between them means the clock runs roughly 38 minutes ahead of the sun: solar noon arrives at about 12:38 rather than 12:00. Under daylight saving the clocks move 60 minutes forward, widening the gap to 98 minutes and pushing solar noon to 13:38.
The longest day of 2026 is 22 June, with 14h 55m of daylight. The shortest is 22 December, with 9h 25m. The swing between them is 5h 30m. 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 Cincinnati the sun comes up earliest on 15 June at 06:11, while the latest sunset waits until 29 June at 21:08. 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 Cincinnati that civil twilight runs about 27 minutes at the equinox, stretching to 32 minutes at the solstice.
