A 17th-century saying held that Isfahan is half the world, and Naqsh-e Jahan Square — roughly 160 by 510 metres — is one of the largest public squares anywhere, laid out in 1602 as a setting for polo, markets and two mosques.
The clock: Iran keeps a half-hour offset at UTC+3:30 and abolished its seasonal change in 2022. Isfahan's Si-o-se-pol bridge has 33 arches and has spanned a river that is now frequently dry.
Isfahan lies at 51.7°E. Its time zone, UTC+3:30, is built around the 52.5°E meridian. The two very nearly coincide: solar noon — the moment the sun is highest — falls at about 12:03, which is as close to true solar time as a zone this wide can get. The zone holds UTC+3:30 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 14h 18m of daylight. The shortest is 22 December, with 10h. The swing between them is 4h 18m. 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 Isfahan the sun comes up earliest on 13 June at 04:55, while the latest sunset waits until 1 July at 19:15. 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 Isfahan that civil twilight runs about 25 minutes at the equinox.
Every figure in this section is computed from the city's own latitude, longitude and IANA time zone using NOAA solar algorithms (Spencer, 1971), accurate to about ±2 arcminutes below 65° latitude.
