Jaffna lies at 80.0°E. Its time zone, UTC+5:30, is built around the 82.5°E meridian. The 2.5° gap between them means the clock runs roughly 10 minutes ahead of the sun: solar noon arrives at about 12:10 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 12h 41m of daylight. The shortest is 22 December, with 11h 34m. The swing between them is 1h 8m. Within a few degrees of the equator the length of the day barely moves all year.
The earliest sunrise and the latest sunset do not land on the longest day. In Jaffna the sun comes up earliest on 29 May at 05:48, while the latest sunset waits until 15 July at 18:35. 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 Jaffna that civil twilight runs about 21 minutes at the equinox.
