Pataliputra, now Patna, was capital of the Maurya empire under Ashoka around 250 BC, and by some estimates the largest city in the world at the time, with several hundred thousand residents inside a timber palisade 33 km long.
The clock: Patna keeps UTC+5:30. Nalanda, about 90 km away, was one of the world's first residential universities, operating from the 5th to the 12th century.
Patna lies at 85.1°E. Its time zone, UTC+5:30, is built around the 82.5°E meridian. The 2.6° gap between them means the clock runs roughly 11 minutes behind the sun: solar noon arrives at about 11:49 rather than 12:00. The zone holds UTC+5:30 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 13h 44m of daylight. The shortest is 22 December, with 10h 32m. The swing between them is 3h 12m. 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 Patna the sun comes up earliest on 10 June at 04:57, while the latest sunset waits until 4 July at 18:44. 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 Patna that civil twilight runs about 23 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.
