The sun and the clock in Yakutsk (2026)
Yakutsk lies at 129.7°E. Its time zone, UTC+9, is built around the 135°E meridian. The 5.3° gap between them means the clock runs roughly 21 minutes ahead of the sun: solar noon arrives at about 12:21 rather than 12:00. The zone holds UTC+9 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 19h 46m of daylight. The shortest is 22 December, with 5h 8m. The swing between them is 14h 38m. Close to the Arctic or Antarctic circle, the year swings hard between long light and long dark.
The earliest sunrise and the latest sunset do not land on the longest day. In Yakutsk the sun comes up earliest on 20 June at 02:29, while the latest sunset waits until 24 June at 22:16. 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 Yakutsk that civil twilight runs about 44 minutes at the equinox, stretching to 66 minutes at the solstice.
