The sun and the clock in Parma (2026)
Parma lies at 10.3°E. Its time zone, UTC+1, is built around the 15°E meridian. The 4.7° gap between them means the clock runs roughly 19 minutes ahead of the sun: solar noon arrives at about 12:19 rather than 12:00. Under daylight saving the clocks move 60 minutes forward, widening the gap to 79 minutes and pushing solar noon to 13:19.
The longest day of 2026 is 22 June, with 15h 36m of daylight. The shortest is 22 December, with 8h 47m. The swing between them is 6h 48m. 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 Parma the sun comes up earliest on 16 June at 05:32, while the latest sunset waits until 28 June at 21:09. 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 Parma that civil twilight runs about 29 minutes at the equinox, stretching to 37 minutes at the solstice.
