The sun and the clock in Diyarbakır (2026)
Diyarbakır lies at 40.2°E. Its time zone, UTC+3, is built around the 45°E meridian. The 4.8° 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. The zone holds UTC+3 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 14h 48m of daylight. The shortest is 22 December, with 9h 32m. The swing between them is 5h 16m. 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 Diyarbakır the sun comes up earliest on 14 June at 04:56, while the latest sunset waits until 30 June at 19:45. 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 Diyarbakır that civil twilight runs about 26 minutes at the equinox, stretching to 31 minutes at the solstice.
