The sun and the clock in Omsk (2026)
Omsk lies at 73.4°E. Its time zone, UTC+6, is built around the 90°E meridian. The 16.6° gap between them means the clock runs roughly 67 minutes ahead of the sun: solar noon arrives at about 13:07 rather than 12:00. The zone holds UTC+6 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 17h 23m of daylight. The shortest is 22 December, with 7h 10m. The swing between them is 10h 12m. 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 Omsk the sun comes up earliest on 18 June at 04:26, while the latest sunset waits until 26 June at 21:50. 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 Omsk that civil twilight runs about 36 minutes at the equinox, stretching to 58 minutes at the solstice.
