The sun and the clock in Giza (2026)
Giza lies at 31.2°E. Its time zone, UTC+2, is built around the 30°E meridian. The 1.2° gap between them means the clock runs roughly 5 minutes behind the sun: solar noon arrives at about 11:55 rather than 12:00. Under daylight saving the clocks move 60 minutes forward, widening the gap to 55 minutes and pushing solar noon to 12:55.
The longest day of 2026 is 22 June, with 14h 5m of daylight. The shortest is 22 December, with 10h 13m. The swing between them is 3h 52m. At this latitude the seasons are visible in the clock, but never dramatic.
The earliest sunrise and the latest sunset do not land on the longest day. In Giza the sun comes up earliest on 23 April at 05:21, while the latest sunset waits until 2 July at 20:00. 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 Giza that civil twilight runs about 24 minutes at the equinox.
