The sun and the clock in Kaunas (2026)
Kaunas lies at 23.9°E. Its time zone, UTC+2, is built around the 30°E meridian. The 6.1° gap between them means the clock runs roughly 24 minutes ahead of the sun: solar noon arrives at about 12:24 rather than 12:00. Under daylight saving the clocks move 60 minutes forward, widening the gap to 84 minutes and pushing solar noon to 13:24.
The longest day of 2026 is 22 June, with 17h 21m of daylight. The shortest is 22 December, with 7h 11m. The swing between them is 10h 10m. 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 Kaunas the sun comes up earliest on 18 June at 04:45, while the latest sunset waits until 26 June at 22:07. 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 Kaunas that civil twilight runs about 36 minutes at the equinox, stretching to 58 minutes at the solstice.
